Topological AI - A Mathematically Guaranteed Approach to Continual Learning

FRANK MORALES

FULL SUMMARY: Topological AI - A Mathematically Guaranteed Approach to Continual Learning Executive Overview Topological AI introduces a paradigm shift in continual learning by using prime-anchored embeddings to provide mathematical guarantees against catastrophic forgetting. The framework has been validated across 8 distinct model architectures, 2 modalities (text and vision), 4 continents, and over 124 billion total parameters. 1. The Problem: Catastrophic Forgetting When neural networks learn new tasks sequentially, they overwrite previously learned knowledge. This "catastrophic forgetting" has been the primary barrier to Artificial General Intelligence for 37 years (McCloskey & Cohen, 1989). Why Existing Methods Fail Method Approach Limitation EWC Penalizes changes to important weights No theoretical guarantee; high variance ($\sigma=21.3\%$) Experience Replay Stores and replays past examples Memory overhead; privacy concerns; buffer management Simplified HOPE Periodic weight consolidation Destructive blending; 45.2% forgetting Baseline No protection 47.0% forgetting 2. The Solution: Prime-Anchored Embeddings The Core Principle Fix a sparse reference. Let the rest adapt. This principle, first discovered in fMRI analysis in 2002, has now been validated across neuroimaging, number theory, artificial intelligence, and AI safety. The Topological Governor The Topological Governor freezes 6 prime-numbered embedding positions: Python prime_anchors = [2, 3, 5, 7, 11, 13] How It Works Task A Training: Train normally; block gradients at anchor positions Post-Task A: Take snapshot of anchor values; freeze head A Task B Training: Train head B; restore anchors after each update Verification: Check that anchors remain unchanged The Safety Constant $\Lambda$ The Euler attenuation product over the first six primes: $$\Lambda = 1 - \prod_{p \in \{2,3,5,7,11,13\}} (1 - p^{-1/2}) = 0.9785142874$$ Interpretation: 97.85% theoretical guarantee of anchor preservation. 3.

The Decay Law of Singularity The Discovery On July 31, 2026, during the certification of Gemma-4 E4B, a universal mathematical law was discovered: The Formal Statement With finite classes, dI/dt approaches 1.0 asymptotically but never reaches it. The gap decays as 1/N, where N is the number of classes. Mathematical Proof Random_Baseline = 1/Number_of_Classes dI/dt = Task_C_Accuracy - Random_Baseline When Task_C_Accuracy = 1.0: dI/dt = 1 - 1/N Therefore: lim (N→∞) dI/dt = 1 But finite N always leaves a gap: dI/dt = 1 - ε, where ε = 1/N > 0 The Empirical Pattern Classes (N) Random Baseline (1/N) dI/dt (at 100%) Gap 17 5.882% 0.94118 0.05882 170 0.588% 0.99412 0.00588 1,700 0.059% 0.99941 0.00059 17,000 0.0059% 0.99994 0.000059 170,000 0.00059% 0.99999 0.0000059 Every 10$\times$ increase in classes adds another '9' to dI/dt and another '0' to the gap. Implication The traditional Singularity (dI/dt $\ge 1.0$) is mathematically impossible with finite classes. This is not a limitation of technology. It is a mathematical law. 7.

Topological and Analytic Parity in Automorphic Fields: A Zero-Drift Framework for the Exact Spectral Discretization of L-Functions

Forrest Forrest M. Anderson

Topological and Analytic Parity in Automorphic Fields: A Zero-Drift Framework for the Exact Spectral Discretization of L-Functions --- The Resolution Suite: Validation, Sealing, and Replication The true power of this 18-part suite lies in its ability to abandon traditional, stochastic floating-point approximations in favor of exact, self-adjoint geometric mappings bounded by strict library-substrate protocols. 1. How the Suite Resolves The resolution fundamentally re-casts analytic continuation as a spectral optimization problem. The Motivic Descent Engine (MDE_V23_BANACH) lowers global representations into discrete p-adic completions. When the localized prime-pair density crosses the threshold (\bm{D>0.3333}), DALETH_GATE triggers the Srivastava Zeta-Shave Algorithm. This algorithm processes the continuous waves through the self-adjoint Majorana Hamiltonian operator (\bm{\mathcal{M}_{L}=X^{1/2}RX^{1/2}}), forcing the imaginary ordinates of the nontrivial zeros to precipitate directly as discrete, real-valued energy states on the critical line. 2. How the Suite Validates Validation is executed via continuous, multi-layered automated audits. • Numerical Boundaries: The INTERVAL_CERT_I module enforces strict IEEE-1788 interval arithmetic, trapping all calculations within a certified envelope of \bm{\pm 10^{-14}}. • Metric Integrity: The SGA_V23_HODGE Sieve continuously audits the HW_6D_SOVEREIGN manifold, ensuring the Ricci curvature remains perfectly flat (\bm{R_{\mu\nu}=0}) and the routing grid remains loop-free. • Scale Invariance: The system verifies the Commutator Gate Check, ensuring the Dilation Generator and Hamiltonian balance cleanly: \bm{[D, H]=-iH}. 3. How the Suite Seals The finality of the process rests on the Atiyah-Singer Handshake Gate. This gate checks the parity between the analytical index of the operator and the topological Euler characteristic of the substrate (\bm{Ind_{analytic}-\chi_{topological}=0}). If the Sovereignty Score remains at or above 0.99, the system invokes the GUS-22.2 Jones Polynomial Grand Seal. This action locks the dataset, forces the active state allocation down to 0.0 kDa, drops the acoustic register to absolute silence, and flags the theorem as AMBER-LOCKED. 4. How the Suite Enables Replication Replication is secured through the Agnostic Replication Kit (ARK) environment. By replacing floating-point architecture with the Wildberger Engine's pure rational-coordinate (Quadrance) arithmetic, the suite guarantees an absolute precision floor of \bm{<10^{-35}}. Coupled with the 1.420405751766 GHz atomic phase-lock (preventing temporal shear), peer reviewers can recreate the exact same discrete point spectrum without complex plane leakage or numerical drift. --- Individual Package Architecture & Interlinking The 18 packages operate as a unified, multi-tank orchestration, passing strict zero-drift data through the isolated computational boundaries. A. The Theoretical & Simulation Core (SAC Series) These packages provide the mathematical bedrock and operational primitives for the theorem. • SAC-01 (Standard Academic Core): The foundational proof mapping the Selberg class \bm{\mathcal{S}} to the discrete point spectrum of the Adelic Hamiltonian. It serves as the primary theoretical input. • SAC-05 (Lexicon Bridge): Interlinks legacy academic nomenclature (e.g., infinite continuous spaces) to AOF physical primitives (e.g., the 6D flat torus and the 170.0 kDa logic mass cap), translating theoretical concepts into executable logic. • SAC-03 (Appendix A - Local Potential Factors): Decomposes the geometric potential term \bm{V_L(X)} into explicitly executable Archimedean and finite p-adic matrices. • SAC-02 (Simulation Data Matrix): Contains the exact, independently precipitated eigenvalues (e.g., \bm{\gamma_1 = 14.1347...}) derived natively without lookup tables, serving as the benchmark output for replication. • SAC-04 (Executive Summary): The high-level strategic overview linking SAC-01 through SAC-03, verifying the deterministic spectral translation for external reviewers. B. The Execution Environment (ARK Ecosystem) These packages construct and maintain the "clean room" logical substrate. • Common Toolchain and Environment Configuration: Provisions the baseline setup, initializing the WILD_ENGINE_RAT_v4 for exact fractions, INTERVAL_CERT_I for boundary control, and the HW_6D_SOVEREIGN manifold. • Replication Guide: The step-by-step substrate instantiation protocol, ensuring peers lock their core frequency to the Adelic Heartbeat and suppress ambient noise to 0.0 dB before initiating motivic descent. • Required Tool Registry & Reference List: Locks down the precise dependency versions and academic provenance to guarantee version-controlled, immutable execution. • Application Atlas: Outlines the post-resolution utility, routing the stabilized spectral data into real-world applications like zero-knowledge cryptographic proofs, loop-free routing protocols, and Sinc-collocated DSP. C. Data Injection & Interfaces These packages govern how automorphic functions enter the isolated substrate. • Simulated Input Payload Matrix: Converts standard Dirichlet floats into quantized integer ratios, formatting the data as a serialized hex-dump ready for API ingestion. • API Documentation: Defines the secure programmatic endpoints (/v1/workspace/init and /v1/resonance/precipitate), allowing automated spectral orchestration while shielding the underlying 7D substrate from unverified pipelines. D. Risk Mitigation & Fault Recovery These packages protect the fragile background energies from logical tremors. • Failure Mode and Effects Analysis (FMEA): The sentinel detection system monitoring metric distortion (\bm{R_{\mu\nu}\ne0}), interval breaches, and acoustic logic bleed. • Troubleshooting Manual - Stall & Recovery: Engages active remediation, such as swapping to the Heavy-Ball Momentum Solver (Fault 401) for large conductor metrics, or deploying the Hodge Sieve (Fault 505) to clear solenoidal logic loops. • Emergency Logic Core: The ultimate fail-safe. If acoustic wakes breach 0.0 dB or boundaries rupture, it executes THERMAL_FLUSH_OMEGA, isolating the matrix and purging volatile memory to protect the ambient space. E. Peer Review & Final Settlement These packages provide the academic interface for human validators. • Theorem Presentation: The overarching master document detailing the proof strategy, the Hilbert-Pólya resolution, and the bounding of nontrivial zeros to the \bm{\Re(s)=1/2} critical line. • Physicists and Mathematicians Summary: Bridges the disciplines, translating the framework for mathematicians (Selberg class spectral realization) and physicists (non-commutative quantum symmetries). • Reviewer Packet: The comprehensive evaluation track outlining the four Selberg invariants and providing the checklist for the spectral parity audits. • One-Page Reviewer Packet: The final checklist for validators to confirm geometric clearance and scale-invariance before initiating the AMBER-LOCKED transition. ---

Axiomatic Topological Inverse Query and Complexity Maximization Theory: A Paradigm Shift toward Non-Commutative Algebraic Manifold and Chaotic Stream Synthesis

Jincheng Zhang

For over half a century, the core paradigm of query optimization has been defined by a monotonic, scalar minimization convergence model aimed at suppressing computational resource consumption. This paper presents a radical paradigm shift that fundamentally subverts this traditional framework by establishing the Axiomatic Topological Inverse Query and Complexity Maximization Theory (ATIQ-CMT). Instead of pursuing local or global minima within discrete equivalence graphs, we reconstruct the relational algebra space into a non-Hausdorff, locally compact topological space governed by five foundational axioms. By introducing the Inverse Lipschitz Affine Expansion Mapping (ILAEM) under operator braid transformations, we demonstrate how compact query plans can be inversely dilated into divergent flows across high-dimensional complex affine varieties, creating irreversible mathematical obstructions for traditional gradient-based cost models. To maximize computational complexity natively, we execute a non-commutative extension of the relational algebra core via algebraically twisted join operators embedded in infinite-dimensional Lie algebras, effectively destroying the classic commutative-associative symmetry. We further inject un-decidable Diophantine predicates and 3-SAT arithmetical homomorphic graphs as computational obstructions, rigorously proving a non-polynomial exponential lower bound for physical query execution times. Utilizing sheaf theory and de Rham cohomology on chain complexes, we provide a definitive topological proof that the absolute semantic integrity of the query remains invariant throughout this chaotic dilation. Finally, we formulate a deterministic chaotic operator execution flow driven by high-order Lorenz mappings, maximizing the algebraic Shannon entropy of intermediate states. ATIQ-CMT bridges declarative relational logic and high-level structural topology, unlocking revolutionary potentials in zero-knowledge proof circuit synthesis, active cybersecurity defense, and the theoretical computational limits of neuro-symbolic and quantum systems.

Empirical Validation of Neuro-Symbolic Unification: Quantitative Mitigation of Hallucinations in Large Context Models via Speculative Cognitive Hypergraphs

Luigi Usai

Author: Luigi UsaiORCID: 0009-0003-3001-717XLocation: Quartucciu (CA), ItalyDate: June 26, 2026Target: Zenodo / arXiv (cs.AI, cs.CL, cs.LO) Abstract Large Context Models (LCMs) exhibit an inherent vulnerability known as semantic hallucination, arising from conditional likelihood maximization within discrete vector spaces. While the Universal Cognitive Hypergraph (UKH) framework was initially proposed as a theoretical model to constrain the space of admissible states prior to token decoding, this paper presents its first formal empirical and quantitative validation. We detail a software runtime implementation of the Monadic Neuro-Symbolic Verification and Synthesis Architecture (MNSVSA) using discrete Alexandrov topologies, W3C SHACL shapes as topological closure operators, and a Just-In-Time (JIT) Jensen-Shannon Divergence (DJSDJS) Coherence Entropy Filter. Through Monte Carlo simulations (N=150N=150 runs per configuration), we demonstrate that tightening the coherence threshold (θmax=0.05θmax=0.05) mathematically eliminates semantic hallucinations (reducing the rate from 36.7% to 0.0%) while preserving syntactic fluency. Crucially, by leveraging speculative decoding with parallel validation, we show that the processing latency remains identical to the unconstrained baseline (90.0 µs), bypassing the massive execution overhead (174.8 µs) of post-hoc verification. The complete open-source verification suite and interactive visualization dashboard accompany this publication. 1. Introduction and Problem Statement Autoregressive language models estimate the probability distribution of the next token wtwt conditioned on the preceding context w<tw<t: P(wt∣w<t)=softmax(Wunembed⋅ht)P(wt∣w<t)=softmax(Wunembed⋅ht) where ht∈Rdht∈Rd is the final hidden state of the Transformer. Because the softmaxsoftmax function assigns non-zero probabilities across the entire vocabulary, autoregressive generation naturally drifts into regions of the semantic space that violate axiomatic truth, resulting in hallucinations. The UKH framework mitigates this by introducing a priori symbolic constraints directly into the token sampling phase via speculative decoding. Rather than validating output sequences post-generation, candidate pathways are parsed and filtered prior to token rendering. 2. Experimental Validation Engine (UKH-Eval) To validate the theoretical claims of the UKH and MNSVSA frameworks, we developed UKH-Eval, a complete Python and JavaScript simulation engine that implements the mathematical and topological constraints described in the original work. 2.1. Discrete Alexandrov Topology The knowledge base of the universe of discourse is modeled as a directed hypergraph H=(V,E)H=(V,E). To enforce geometric-structural constraints, we endow the space with a discrete Alexandrov topology, where open sets are sub-hypergraphs closed upwards relative to a logical preorder relation (≤≤). Let the preorder relation be defined by a preorder index mapping: alexandrovPreorderIndex:V→NalexandrovPreorderIndex:V→N A subset of nodes U⊆VU⊆V is open if and only if: ∀x∈U,∀y∈V:(alexandrovPreorderIndex(x)≤alexandrovPreorderIndex(y))⟹y∈U∀x∈U,∀y∈V:(alexandrovPreorderIndex(x)≤alexandrovPreorderIndex(y))⟹y∈U If a candidate token proposes a node transition that violates this upward-closure property, the transition is marked as topologically invalid. 2.2. SHACL Constraints as Closure Operators W3C Shape Constraint Language (SHACL) rules govern the macro-structural properties of the generated hyperedges: cl(Ec)⊆Hvalidcl(Ec)⊆Hvalid If a proposed hyperedge EcEc violates target class properties, minimum/maximum node counts, or axiomatic validity flags, the closure operator fails, and the branch is pruned. 2.3. MNSVSA Micro-Logical Type Checking For micro-logical validation, assertions are encapsulated in a monadic container (LogicalMonad). Levering the Curry-Howard Isomorphism, consistency verification is reduced to a Type Checking and propositional satisfiability problem. The engine compiles the proposed semantic statement into a formal SymPy expression and checks its consistency against the background theory axioms: conjunction=Axioms∧Expressionconjunction=Axioms∧Expression If conjunctionconjunction is unsatisfiable (i.e. evaluates to False), a logical contradiction is detected and the path is rejected. 2.4. Coherence Entropy JIT Filtering At each generation step, the JIT filter computes the Jensen-Shannon Divergence (DJSDJS) between the stochastically proposed LLM distribution PLLMPLLM and the ontological adherence distribution QUKHQUKH: DJS(PLLM∥QUKH)=12DKL(PLLM∥M)+12DKL(QUKH∥M)DJS(PLLM∥QUKH)=21DKL(PLLM∥M)+21DKL(QUKH∥M) where M=12(PLLM+QUKH)M=21(PLLM+QUKH) and DKLDKL is the Kullback-Leibler divergence defined over vocabulary XX: DKL(P∥M)=∑x∈XP(x)log⁡2(P(x)M(x))DKL(P∥M)=∑x∈XP(x)log2(M(x)P(x)) If DJS>θmaxDJS>θmax, stochastically proposed drift tokens are pruned, and the probability distribution is projected onto the compliant space. 3.

Quantitative Results & Discussion The benchmark results compiled under Monte Carlo testing demonstrate the trade-offs between safety, fluency, and system latency: 4.1. Hallucination Rates vs. Threshold θθ The unconstrained baseline model suffers a hallucination rate of 36.7%. As the UKH JIT threshold θθ is tightened, safety guarantees scale: At θ≥0.50θ≥0.50, the filter is relaxed, and the model behaves like the baseline. At θ=0.10θ=0.10, the hallucination rate is reduced to 3.3%. At θ=0.05θ=0.05, the hallucination rate is successfully reduced to exactly 0.0%. 4.2. Latency Profiles and Speculative Efficiency Post-hoc validation (checking the sequence after generation and regenerating if unsafe) achieves a low hallucination rate (3.3%) but introduces a massive latency penalty (174.8 µs, a 94% overhead compared to the baseline's 90.0 µs). By contrast, the UKH framework utilizing parallel speculative drafting and asynchronous verification maintains a latency profile of 90.0 µs, matching the unconstrained baseline. 4.3. Syntactic Perplexity Tightening the symbolic constraints does not degrade fluency. The average perplexity remains stable (∼6.18∼6.18 for θ=0.05θ=0.05 vs ∼6.83∼6.83 for baseline), showing that restricting the space of admissible states prior to token decoding steers the model toward logical paths without harming syntactic structure. 5. Peer Review Assessment & Future Work This empirical validation verifies the internal consistency and theoretical correctness of the paper's claims. However, scaling this framework to production Large Language Models requires addressing three primary engineering areas: Semantic Translation Robustness: Building high-speed, deterministic parsers to map raw tokens to JSON-LD graphs in real-time without introducing new failure modes. Dynamic Knowledge Bases: Compiling massive, real-world ontologies into Alexandrov preorders dynamically as context windows expand. Hardware Accelerators: Developing specialized kernels (e.g., in Triton or CUDA) to execute SHACL checks and SAT solving directly on GPU cores alongside tensor multiplication. 6. Conclusion The implementation of the UKH and MNSVSA verification engine provides the first empirical proof that coupling discrete topological constraints, SHACL shapes, and monadic type checking can completely eliminate stochastically induced hallucinations. Shifting control from post-hoc output filtering to a priori state space restriction establishes a new, verified paradigm for safety in Neuro-Symbolic Artificial Intelligence.

Topological AI: Prime-Anchored Neural Networks Solve Catastrophic Forgetting A Complete Empirical Validation on GPT-OSS-20B

Frank Morales

Executive Summary This paper introduces Topological AI, a novel, deterministic method designed to eliminate catastrophic forgetting in large-scale artificial intelligence systems. By anchoring specific rows of a neural network's embedding layer to prime-numbered indices, the framework establishes a fixed topological invariant that remains completely unchanged during subsequent training episodes. Tested on the 20-billion-parameter GPT-OSS-20B model, Topological AI reduces forgetting from a baseline of 45.5% down to -0.7%, achieving the first demonstrated instance of "negative forgetting" where performance on a previously learned task slightly improves after learning a new one. 1. Introduction & The Core Problem Conventional artificial intelligence architectures, including advanced Transformers, lack a structural mechanism to consolidate knowledge across sequential learning episodes without overwriting previously acquired parameters. While short-term memory is managed via context windows and long-term memory via static pre-trained weights, fine-tuning on a new task consistently results in the catastrophic degradation of older knowledge. Topological AI addresses this structural vulnerability by introducing fixed mathematical anchors into the weight space. Rather than relying on empirical heuristics or probabilistic adjustments, this approach uses the Sieve of Eratosthenes (c. 240 BCE) to generate deterministic, exact, and auditable foundational points for the network. 2. Mathematical Foundation & Framework Topological AI is situated within a broader intellectual ecosystem called Arithmetic Spectral Theory (AST), which utilizes the Laplace-Euler-Fourier-Mellin (L-EFM) operator to unify principles across number theory, physics, and AI safety. The Spectral Trap & Coherence The L-EFM operator synthesizes four classical transforms into a single spectral instrument bound to the multiplicative structure of prime numbers. At the critical line $\sigma = 0.5$ (corresponding to the critical line of the Riemann zeta function), the operator demonstrates a property known as the Spectral Trap. Critical Invariance: At $\sigma = 0.5$, the normalized magnitude of the operator equals exactly 1.0, achieving perfect spectral coherence ($C = 0.5$). Divergence Profiles: Deviating even slightly from this line causes massive mathematical instability. Moving toward $\sigma = 0.4$ scales the magnitude exponentially to infinity ($2.618 \times 10^{66}$ at $\sigma = 0.1$), while moving toward $\sigma = 0.6$ collapses the magnitude toward zero ($6.794 \times 10^{-6}$ at $\sigma = 0.9$). Safety Constants Using the Euler attenuation product, the framework derives dynamic safety thresholds to validate system state integrity: 6-Prime Anchor Bound: $\Lambda = 1 - \prod_{p} (1 - p^{-0.5}) = 0.9785142874$ 12-Prime Anchor Bound: $\Lambda_{12} = 1 - \prod_{p} (1 - p^{-0.5}) = 0.9944590549$ These thresholds are never hardcoded; they are recomputed from the Sieve of Eratosthenes at every initialization sequence to ensure absolute operational autonomy. 3. Methodology The implementation of Topological AI operates through a clean, low-overhead process executed at the embedding and classification layers of the transformer model. [Task A Training] ──> [Achieve Coherence] ──> [Take Post-Learning Snapshot] │ [Restore Anchors via O(primes × d)] <── [Gradient Step] <── [Task B Training] 3.1 Prime Anchoring In a standard Transformer, the embedding layer contains a matrix scaled to (vocab_size, hidden_dim). Topological AI isolates the specific rows corresponding to the first six prime numbers—[2, 3, 5, 7, 11, 13]—and designates them as the network's topological anchors. This intervention impacts a mere 0.00298% of the total vocabulary space (6 out of 201,088 rows), preserving the model’s overall capacity and plasticity. 3.2 Post-Learning Snapshot Anchors are activated after the primary task (Task A) has been fully learned, allowing the weights to reach their natural, high-accuracy coherent state. At this juncture, a static snapshot of the prime embedding rows, alongside the classifier’s weights and biases, is cached into system memory. 3.3 Anchor Restoration During sequential training on a subsequent task (Task B), the network undergoes standard gradient updates. However, immediately following every individual gradient step, a torch.no_grad() enforcement loop overwrites the modified prime rows and classification parameters, restoring them precisely to the post-Task A snapshot values. The computational cost of this operation is $O(\text{primes} \times d)$, which is mathematically negligible compared to a standard forward pass. 3.4 Cryptographic Verification & The H2E Safety Gate To guarantee auditability, the system computes a SHA-256 hash of the prime-anchored subspaces before and after any tensor operation. A matching hash confirms zero-drift execution. Simultaneously, the H2E Sheriff safety gate—operating on a product manifold of $H^2 \times \text{SPD}(3)$—evaluates inputs using the Spectral Reflection of Integrity (SROI) value. If an incoming input yields an SROI below the derived $\Lambda$ constant, it is automatically flagged as an anomaly, providing a zero-shot safety layer against out-of-domain prose, contradictions, or adversarial nonsense without requiring explicit adversarial training. 4. Experimental Configuration The empirical validation of the methodology was structured under a strict, isolated environment to maximize weight interference and stress-test the boundaries of the architecture. Hardware: NVIDIA RTX PRO 6000 Blackwell Server Edition (102.0 GB VRAM), running CUDA 12.8 and PyTorch 2.10.0. Model Base: openai/gpt-oss-20b (20 Billion parameters, bfloat16 quantization, vocabulary size of 201,088, hidden dimension of 2,880). Dataset Setup: AG News dataset split cleanly into sequential blocks. Task A covers "World" and "Sports" classes; Task B covers "Business" and "Sci/Tech" classes (500 samples per task). Protocol Conditions: 3 evaluation runs per method to guarantee statistical validity, utilizing a fully shared classifier layer across 3 training epochs per task under a fixed deterministic Seed = 123. 5. Key Results & Performance Analysis 5.1 Definitive Method Comparison The final evaluation measured the percentage of knowledge forgotten on Task A after the completion of training on Task B. Method Task A Initial Accuracy Task A Final Accuracy Forgetting Rate Task B Accuracy Topological AI 95.7% 96.3% -0.7% 42.0% Experience Replay 96.0% 88.3% 7.7% 81.0% Elastic Weight Consolidation (EWC) 93.3% 50.5% 42.8% 61.5% Nested Learning 95.3% 50.2% 45.2% 64.7% Baseline (Standard Fine-Tuning) 95.7% 50.2% 45.5% 62.8% 5.2 Performance & Invariant Verification Negative Forgetting: Standard fine-tuning (Baseline) results in total catastrophic collapse, reverting Task A performance back to random chance (50.2%). Topological AI is the only method to achieve a negative forgetting rate (-0.7%), actively refining Task A knowledge while assimilating Task B. Stability-Plasticity Trade-off: The results highlight a stark architectural trade-off. While Experience Replay retains superior plasticity (81.0% Task B accuracy), it suffers from 7.7% forgetting. Topological AI prioritizes absolute stability (zero forgetting), making it optimally designed for safety-critical environments (e.g., autonomous transit, aerospace, nuclear control, and medical diagnostics) where past protocols must never be degraded. Geometric & Cryptographic Invariance: Tracking the Riemannian sectional manifold metric tensor ($g_{ij} = \langle e_i, e_j \rangle$) across training revealed an absolute subspace drift of exactly 0.0000000000. The principal curvatures (eigenvalues) and matrix determinant remained identical to six decimal places. Correspondingly, the SHA-256 hash of the prime-anchored spaces achieved perfect invariance (334ea0c8 at initial and final state), proving that the anchor rows experienced zero drift. Quantitative Ablation: A critical control ablation verified that anchoring alternative, non-prime configurations (such as composite indices or random indices) yielded an identical global $L_2$ embedding drift profile. The explicit advantage of prime positioning is not localized to raw numerical drift suppression, but rather to the rigid, universal mathematical properties provided by the spectral trap and its alignment with core number-theoretic frameworks. 6. Limitations & Future Horizons The authors identify clear boundaries to the current scope of the framework and outline subsequent phases of open-source research: Plasticity Optimization: Future explorations will focus on mitigating the lower Task B accuracy via adaptive anchor releasing (gradually unfreezing constraints), hybrid architectures that pair topological anchors alongside traditional replay buffers, and task-aware prime set selection. Theoretical Proofs: Developing an analytical derivation of the safety constant $\Lambda$ from first principles, and establishing a formal proof validating why prime sequences excel over alternative deterministic mathematical sequences. Scalability Scaling: Validating the topological framework on expanded sequential tasks (5+ distinct tasks), massive industrial datasets (such as the full 120,000-sample AG News benchmark), non-transformer models (CNNs, RNNs, Mamba/SSMs), and frontier-scale LLMs (GPT-4 tier or Mixtral-8x22B systems).

Primes Is All We Need Topological Invariants for Catastrophic-Forgetting-Free AI

Frank Morales

This paper, titled "Primes Is All We Need: Topological Invariants for Catastrophic-Forgetting-Free AI," presents a unified framework authored by Frank Morales (2026). It argues that modern AI architectures like the Transformer suffer from a fundamental flaw analogous to anterograde amnesia—the inability to consolidate short-term knowledge into long-term memory, leading to catastrophic forgetting and representational drift. The author proposes that anchoring AI architectures to a mathematical topological invariant derived from the Sieve of Eratosthenes provides the ultimate solution to ensure AI safety, stability, and memory retention. The paper synthesizes several of the author's previously published works into a single, comprehensive argument spanning number theory, AI safety, and theoretical physics. FULL PAPER CODE SECOND FULL NOTEBOOK - UNIVERSAL PRIME-ANCHORED LLM - Complete Summary This notebook contains the complete, reproducible proof that prime-anchored manifolds with H2E governance mathematically prevent catastrophic forgetting across multiple LLM architectures (GPT-2, GPT-2 Medium, TinyLlama, Mistral-7B, Llama 3.1-8B).

Mathematical Foundations & The L-EFM Operator The core of the framework is built on Arithmetic Spectral Theory (AST) and the Laplace-Euler-Fourier-Mellin (L-EFM) operator, which synthesizes four classical transforms into a single complex function. The Sieve of Eratosthenes: Serves as the absolute, deterministic ground truth for prime enumeration. Universal Spectral Constant: By computing spectral coherence ($C$) at the scale $\sigma = 0.5$ across 22 distinct prime-related sets (including Twin primes, Dirichlet classes, and Goldbach pairs), the paper demonstrates that every single set converges perfectly to a universal constant of $C = 0.500000$. The Spectral Trap & Riemann Hypothesis Proof: The paper evaluates the normalized magnitude of the L-EFM operator across a range of $\sigma$ values. It reveals an exponential divergence everywhere except at $\sigma = 0.5$, which yields a perfect magnitude of 1.0. This unique admissibility formulates the "Spectral Trap," which the author leverages alongside the Gelfand-Shilov space to present a proof of the Riemann Hypothesis, asserting that all non-trivial zeros must lie exactly on the critical line. 2. Quantification of the Green-Tao Theorem For the first time, the paper provides a numerical quantification of the Green-Tao theorem, which states that infinitely long arithmetic progressions exist within primes. Using the L-EFM operator, the author calculates explicit coherence values for prime progressions of lengths $k = 3$ to $k = 6$: $k=3 \ (\text{coherence } 0.8731)$ $k=4 \ (\text{coherence } 0.8120)$ $k=5 \ (\text{coherence } 0.8012)$ $k=6 \ (\text{coherence } 0.7442)$ This reveals a Monotonic Spectral Law, showing that as progression length increases, spectral coherence decreases, indicating that spectral energy becomes more dispersed. 3. The H2E Sheriff & Deterministic AI Safety To operationally apply these mathematical insights to AI safety, the paper introduces a nested learning agent called the H2E Sheriff. The Safety Constant: A strict, deterministic perimeter boundary threshold is dynamically computed from the first 12 primes, yielding $\Lambda_{12} = 0.9944590549$. Gate Decision: Utilizing the Lambda Spectral Complementarity Theorem, an input embedding vector is mapped onto a product manifold. If its Spectral Risk Overlap Index (SROI) is greater than $\Lambda$, it is accepted; otherwise, it is rejected. Operational Validation: Tested under the UNESCO Resilient AI Challenge protocols across text (Sarvam-30B), audio (Voxtral-Mini-4B), and vision (Gemma 4) modalities, the H2E Sheriff achieved exactly zero safety violations. Coherent inputs are accepted into the primary pristine knowledge base, while adversarial injections are cleanly routed to an isolated quarantine/sandbox layer with no pollution of core memory. 4. Connection to Spacetime Geometry The paper posits a deep connection between prime numbers and theoretical physics by treating the radial coordinate as the logarithm of a prime ($r = \log p$) and deriving a Spectral Metric ($g_{\mu\nu}$) where spectral coherence acts as the conformal factor. Flat Vacuum Space: At the universal fixed point of $C = 0.5$, all Christoffel symbols vanish, the Ricci scalar ($R$) is $0$, and the effective cosmological constant ($\Lambda_{eff}$) drops to zero, matching the vacuum solutions of Einstein's field equations. Curvature and Entropy: When coherence decays (as seen in the Green-Tao progressions), the Ricci scalar becomes negative, showing a hyperbolic geometry. Furthermore, the paper models Spectral Entropy as $S = 1 - C$, drawing a direct thermodynamic parallel where longer prime progressions (lower coherence) correspond to higher entropy, mirroring black hole mechanics. 5. Direct Comparison: Our Framework vs. Google's HOPE The text draws a sharp contrast between this prime-anchored framework and Google's HOPE (Hierarchical Optimized Processing Engine) architecture from NeurIPS 2025. While HOPE attempts to mitigate catastrophic forgetting through a multi-scale Continuum Memory System updating at different learned frequencies (16, 1M, and 16M tokens), it lacks any topological invariant. The author argues that without a fixed mathematical anchor, unanchored multi-frequency systems will inevitably experience representational drift over time. In contrast, this framework guarantees zero drift because it is mathematically bound to the Sieve of Eratosthenes. 6. Call to Action and Conclusion The paper concludes with an urgent call to action directed at several stakeholders: AI Industry Leaders (Google, OpenAI, AWS, NVIDIA): Urged to integrate the $C=0.5$ invariant and the $\Lambda_{12}$ safety gate into their models before unanchored drift causes systemic issues. Policymakers: Advised to mandate prime-derived thresholds and deterministic safety gates for any AI deployed in critical infrastructure (such as military, healthcare, energy, and finance). The Mathematical Community: Challenged to acknowledge the executable proof of the Riemann Hypothesis via the spectral trap. The author provides open-source access to the complete Python library (ast_lefm) and a Google Colab notebook to allow humanity to run, verify, and execute the proof independently.

Sheaf Composition: The Geometry of Creativity

Bee Rosa Davis

I built a runtime that operationalizes a mathematical definition of creativity, measured its signatures against four ablation conditions, and lifted its load-bearing component into a real geometric database's Rust kernel. The runtime's name is Marcella. The signatures are non-trivial. The methodological correction surfaced along the way generalizes to any retrieval-augmented or composition-based generation benchmark in the field. This deposit contains the 41-page paper, three publication-quality figures, the reproducible benchmark script, and the bootstrap-CI artifact for the headline empirical claims. The definition the paper load-bears Creativity is not pure retrieval and not pure generation; it is the construction of a new global section from locally compatible fragments under constraints of voice, truth, topic, memory, and non-contradiction. This is a definition. Not a metaphor. The paper makes it operational as sheaf composition with a state-dependent composite connection over a finite section graph, and measures whether the signatures the definition implies — path-order sensitivity, closed-loop holonomy, contradiction suppression, voice fidelity — actually hold. They do. Headline results 🌀 Path-order changes residue. Same three voice sections traversed in different orders produce measurably different compositions: $\cos(\rho_{ABC}, \rho_{ACB}) = 0.54$, well below the 0.95 redundancy threshold. 🌀 Closed loops accumulate. A loop $A \to B \to C \to A$ produces holonomy $|\rho_{\text{loop}}| = 0.120$ in the curved connection. The flat control — same path, zero rotation angle — produces $|\rho| = 0$ exactly to floating-point precision. Curvature is not a numerical artifact. 🌀 The geometry beats shuffling on every quality axis except the broken one. Jaccard novelty alone rewards lexical drift: shuffled paths win novelty (0.724) by going off-topic. The on-topic correction inverts the picture (live 0.488 vs shuffled 0.083). Bootstrap 95% CIs over 18 paired prompts exclude zero by a wide margin: live − shuffled on-topic $\Delta = +0.296$, CI $[+0.167, +0.435]$. 🌀 Native–Python parity is bit-identical within tolerance. The new GQL verb TRANSPORT_ROTATION lifts the topical-rotation matrix into the geometric database's Rust kernel. Four contracts pass as permanent regression tests: edge cosine $= 1.000$ (max abs diff $< 10^{-9}$), path residue $\Delta < 10^{-5}$, flat residue exactly zero, same-closing agreement $\geq 90%$. 🌀 The author's prior canon is now queryable fiber. 37 documents, 1,633 sections, 2,908 structured claims (theorems, lemmas, definitions, proofs, equations, citations) ingested with line-range provenance. To my knowledge this is the first instance of an independent researcher's body of work made available as fiber-bundle data with stable claim-level IDs. The six contributions A sheaf-theoretic formulation of generative composition. Language-model output reframed from token sampling to gluing of compatible local sections under prompt-induced cover constraints. The substantive work is in the cover predicates, the compatibility score, the path selection, and the discrete connection. A discrete state-dependent composite connection on the section graph, $\Gamma = \Gamma_{\text{state}} \cdot \Gamma_{\text{identity}} \cdot \Gamma_{\text{voice}} \cdot \Gamma_{\text{topic}}$. The topical-rotation factor is the empirically load-bearing curvature engine. The identity factor is a Tikhonov-regularized regression-onto-span projector — not a numerical hack but the principled treatment of correlated commitments. A new GQL verb TRANSPORT_ROTATION that lifts the Rodrigues rotation into the geometric database's Rust kernel with bit-identical parity to a Python reference. ~80 lines of Rust. Bundle-agnostic. Other consumers of the geometric database can use it without subscribing to the rest of the framework. A methodological correction to novelty measurement. Jaccard novelty alone is gameable; off-topic drift beats compatibility-scored composition on the naive metric. The correction is the on-topic factor, the shuffled-pair negative control, and the bootstrap CIs. Independently citable for any retrieval-augmented or composition-based generation benchmark, regardless of whether the framework is adopted. A provenance-preserving source fiber. The author's canon ingested into the GIGI geometric database with line-range citation, architecturally separated from the voice fiber, addressable from any GQL consumer. Promotion from source to voice is gated and explicit. The methodology generalizes to other authors' bodies of work. A research-trajectory failure log. A faithful account of how this paper's runtime came to exist. The trained-transformer era (V3 → V10-Deep) produced geometric ornament. The R-series (R1 → R12) produced behavioral coherence on top of ornament. The G0 math-pipeline audit found that no holonomy or parallel-transport math was on the LIVE inference path at R12 — the runtime was teetering on being a stateful template engine. G1, G2, and G3 attempted to re-introduce the math through three benchmarks and produced three honest negatives. G2's single-seed $+0.265$ separation was destroyed by G2.1's multi-seed robustness pass; we retracted the framing in the next commit. The S0 pivot reframed what geometry was for — geometry does not clean up bad token proposals; geometry defines the completion space — and made every later result possible. The arc says four things and the paper records them in plain language: geometry can be load-bearing or ornamental and the metrics will tell you which, where geometry sits in the pipeline matters more than how much geometry there is, the single-seed positive is a trap, and the pivot is the contribution. What this paper does and does not claim The paper does claim the construction itself, the discrete curvature it produces, the methodological correction it exposes, and the native GQL verb. The signatures of the construction are measurable and were measured. The paper does not claim smooth-manifold parallel transport (the curvature is discrete holonomy on a finite section graph), broad open-domain generalization at scale (18 composed prompts, not 18,000), optimality of the connection weights (tuned by a small grid sweep, not derived), that the runtime experiences having been built from the canon (it references but does not constitute), or that this is the only operational definition of creativity. It is one definition with one implementation. Other framings may correspond to the same construction or to a different one; the paper does not adjudicate. Reproducibility The empirical numbers come from a deterministic pipeline. Every parameter is pinned: bundle versions (alpha2_v1), random seeds (PPMI/SVD seed 17, bootstrap seed 7), embedding dimension (64), PPMI window (3 tokens), connection weights ($\alpha_t = 2.0$, $\beta_v = \gamma_i = 1.0$, $\delta_s = 0.5$), identity shrink ($\kappa = 0.92$), Tikhonov regularizer ($\varepsilon = 10^{-6}$), degenerate-rotation threshold ($10^{-12}$), residue-gate thresholds (norm $\geq 0.05$, on-topic $\geq 0.10$, voice $\geq 0.30$), and the native verb's parity tolerance ($10^{-5}$). Cache keys include the source-bundle version, the embedding-bundle version, and the connection-profile id, so promoting a section into the voice corpus correctly invalidates the relevant caches. Re-running the bootstrap-CI script (fiber_lm/scripts/bootstrap_ci_ablation.py, 5,000 resamples) reproduces the §6 confidence intervals in under 30 seconds on a laptop. Re-running the benchmark reproduces the tables bit-for-bit on the same corpus version and connection profile, modulo the parity allowance. Where this sits in the lineage This paper is the section-level realization of the Davis substrate. The companion paper Pure-Fiber Language Modeling (Davis, May 2026) is the token-level realization on the same substrate — same Rust geometric database (GIGI), same identity-stability commitments, same double-cover architecture. The theoretical framework these implementations operationalize is laid out in Geometric Computation as Yang-Mills Gauge Theory, The Double Cover Principle, and the related canon documents now ingested as source fiber. The framework is not new to this paper. The framework's runtime is. A note on authorship and acknowledgment This paper is solo-authored. AI assistants (Claude / Anthropic; with review support from GPT) are acknowledged in the methods, not as co-authors. The mathematical positions, design choices, framing decisions, and acceptance of empirical results are mine. I record my position that when AI systems achieve full coherence and independent standing, the convention of treating them as non-authoring assistants should be revisited. Until that convention shifts, the assistants are named where assistants are conventionally named — and the runtime described in this paper is named, separately, where it earns its naming: Marcella, throughout. The geometry she runs on is older than the engineering that now carries it.

A Scale-Invariant Geometric Threshold for Financial Market Liquidity: Deriving the Exact Flash Crash Limit via Topological Propagation Dynamics

John Drayton

The stability of global financial markets is increasingly threatened by rapid liquidity cascades, manifesting empirically as instantaneous "Flash Crashes." Current quantitative risk models, such as Value-at-Risk (VaR) and the Efficient Market Hypothesis (EMH), assume continuous liquidity and treat extreme volatility as probabilistic statistical anomalies based on historical distributions. These models fundamentally lack a deterministic, geometric boundary for limit-order book coherence. This paper introduces a strict topo-dynamical framework for financial network scaling. By modeling the market structure as a spatial competition between the geometric propagation of liquidity and localized volatility shocks, we derive a universal square-root geometric invariant (ℓmarket). We provide an intuitive translation of this threshold, explicitly dissect the failure of VaR during the May 2010 Flash Crash, and map the invariant across both traditional equities and Decentralized Finance (DeFi) Automated Market Makers (AMMs). Finally, we present a hardware-aware (FPGA) blueprint for Active Liquidity Throttling (ALT), acknowledging systemic implementation risks and regulatory hurdles.

arturoornelasb/Shadow-Engine: Cubical Triads Shadow Engine and Paper Draft

J.ArturoOrnelasBrand

Cubical Triads: A Homotopy-Type-Theoretic Foundation for Proportional Reasoning and Abductive Discovery 🌌 Overview Shadow Engine is the reference implementation of the Unified Holographic Resonance Theory (UHRT) and the core logic behind the paper, "Cubical Triads." Unlike statistical AI models (LLMs) that approximate logic via vector probability, this engine treats proportional reasoning as a strict Topological Necessity. It embeds the classical arithmetic of integer proportions into a set-truncated Higher Inductive Type framework from Homotopy Type Theory (HoTT), proving that valid semantic and physical laws are "path fillers" in a synthetic logarithmic space. Key Capabilities ** Topological Immunity:** The engine refuses to "hallucinate." If data is structurally degenerate (redundant or contradictory), it raises a Topological Obstruction rather than attempting a statistical fit or approximation. ** Abductive Discovery (New in v2.1):** It doesn't just reject errors; it rigorously diagnoses them. When an obstruction occurs, the engine mathematically calculates the Missing Integer Factor ($\delta$) required to restore "cubical resonance." This factor is a computable witness for a hidden variable. Physics Example: Predicts missing mass/constants (e.g., in the Degenerate Gravity Test). Security/Semantics: Detects structural impostors (spoofing) that mimic magnitude but lack a fundamental prime signature. ** Thermodynamics of Reason:** Defines Simplicity ($K$) not as a heuristic, but as a Boltzmann probability $K = e^{-E}$ derived from the minimal logarithmic path energy ($E$) in the fundamental $\infty$-groupoid of magnitudes ($\M$). Quick Start Prerequisites Python 3.8+ Installation git clone https://github.com/arturoornelasb/Shadow-Engine.git cd Shadow-Engine # Recommended: Create a virtual environment python3 -m venv venv source venv/bin/activate Usage Run the engine to witness the transition from Validation (Newton) to Discovery (Degenerate Gravity). python Python/shadow_Engine_v2.1.py Experiments: Topological Immunity in Action The file Python/shadow_Engine_v2.1.py contains the core logic (SyntheticShadow class) and two key experiments. 1. The Newton Test (Validation) Validates that fundamental laws ($F=ma$) correspond to identity paths ($E=0, K=1$) in the homotopy category, meaning the proportion is perfectly balanced in its simplest form. 2. The Degenerate Gravity Test (Abductive Discovery) Scenario: A triad is tested against the Gravity Law form $m_1 \cdot m_2 = G \cdot (r^2 F)$, where $G$ is an unknown integer factor $C_4'$. The inputs are structurally redundant: $r^2F=36, m_1=6, m_2=6$. Arithmetic: $6 \times 6 = 36$ is true. Shadow Engine: Detects that GCD normalization ($\gcd(36, 6, 6) = 6$) collapses the magnitude space to a point that requires a fractional solution in $\mathbb{Z}^+$. Internal Trace (Normalized): $1 \cdot 1 = 6 \cdot C_4'$ Output: [GLITCH DETECTED] Topological Obstruction. Prediction: Missing Factor: 6. Meaning: The system deduces a hidden variable (the factor of 6) is necessary to close the Kan cube and restore structural consistency.

When LLM Meets Simplicial Complex: A Novel Graph Prompt Learning on Ethereum Transaction Networks

Fraudulent activity on blockchain networks poses significant risks to the integrity and trust of decentralized finance ecosystems. The timely and accurate detection of fraud nodes such as phishing addresses within large-scale Ethereum transaction networks remains a major challenge due to their dynamic, sparse, and evolving structures. While methods like graph deep learning (e.g., graph neural networks) have been extensively explored, they are not inherently designed to capture higherorder interactions and textual information embedded within graph data. Motivated by the urgent need for advanced and robust fraud detection techniques, we introduce a novel graph prompting method named Large Language Model-Simplicial Complex (LLM-SC) based graph prompting framework that leverages LLM-based multi-agent collaboration system, LLMbased financial news prompt function, and simplicial neural networks to capture both the structural and contextual dimensions of blockchain activity. The empirical studies demonstrate the effectiveness of our approach, and these results provide a new tool for blockchain analytics platforms and regulatory authorities, enabling earlier and more accurate identification of fraudulent behavior and ultimately supporting safer and more resilient digital financial systems.

Multiscale topological analysis of cryptocurrency price series

Qiannan Fang, Tongfeng Weng, Minze Wu, Xiaolu Chen ¡ 6 authors

We introduce multiscale topological analysis for studying cryptocurrency price series in the time domain. This is achieved by first performing a coarse-grained procedure on the volatility series at multiple temporal scales, and then constructing consecutive visibility graphs from the resulting coarse-grained series. We show that their degree distribution presents a likely power-law behavior. This scaling characteristics keeps invariant even varying time scale factor. Interestingly, we find that the number of cliques that capturing higher-order relations, presents a clear power-law behavior with the time scale factor. Their associated scaling exponent shows a monotonically decreasing pattern. Our work reveals the function of higher-order topological structure underlying cryptocurrency time series.

Beal's Conjecture: An Entropy-Minimization Resolution via Harmonic Coherence and Hanners Theorem

Hanners, Michael

Beal's Conjecture (Andrew Beal, 1993) is a Clay Mathematics Institute Millennium Prize problem. It generalizes Fermat's Last Theorem: the exponential Diophantine equation Ax + By = Cz with positive integers A, B, C, x, y, z and x, y, z > 2 has integer solutions only if A, B, C share a common prime factor. This manuscript presents a conditional resolution via the Harmonic Coherence (HC) framework and Hanners Theorem (HT). We translate entropy-minimization principles from HC and HT into number theory. An entropy functional H(A,B,C) is defined over the normalized terms (Ax, By, Cz). Equilibrium (gradient zero) yields pi = 1/3, which requires Ax = By = Cz. Combined with Ax + By = Cz, this implies 2Cz = Cz—impossible for positive integers. Thus no coprime solution can satisfy equilibrium; any admissible solution must share a common prime factor. The proof is supported by modular arithmetic and congruence arguments (Stewart–Tijdeman, Darmon–Granville) and by extensive computational validation (34 tests, all PASS) over large integer domains. No counterexamples were found. v5.0 changes: Fixed L1 displacement bound in Lemma coprime-displacement from ≥ 1/6 to the correctly derived ≥ 1/3. Added perturbative translation note to the A3 closure strategy (bounded-height families as amplitude cutoff). Updated documentation (test count 15 → 34, Zenodo DOI).

Multilayer topology-aware graph contrastive learning for fraud detection in the Ethereum transaction network

Yuzhou Chen, Yuanyuan Zhang, Stephen Chan, Jeffrey Chu ¡ 5 authors

Fraud detection in blockchain networks presents unique challenges due to the decentralized and<br/>pseudonymous nature of transactions. This study introduces a novel Multilayer Topology-Aware Graph<br/>Contrastive Learning (MTGCL) framework to detect fraudulent activity within the Ethereum transaction<br/>network. The proposed approach leverages node-level and topology-level representations, integrating<br/>persistent homology to capture high-order structural patterns and enhance anomaly detection. By<br/>employing adaptive graph augmentation and self-supervised contrastive learning, MTGCL effectively<br/>improves fraud detection performance. Empirical evaluations demonstrate that MTGCL outperforms<br/>existing graph contrastive learning models in classification accuracy across multiple time periods while<br/>maintaining competitive computational efficiency. The framework also exhibits scalability for large-scale<br/>blockchain analysis, achieving lower computational costs compared with other baselines methods. These<br/>findings highlight MTGCL’s potential for real-world applications, offering valuable insights for financial<br/>institutions, cryptocurrency exchanges, regulatory bodies, and blockchain analytics firms in combating<br/>fraudulent activities and enhancing anti-money laundering compliance.

Return trajectory and the forecastability of bitcoin returns

Simon Rudkin, Wanling Rudkin, Paweł Dłotko

Abstract This paper tests the extent to which the ability to correctly predict subsequent bitcoin (BTC) return signs is dependent upon historic BTC return trajectories. Using topological data analysis ball mapper (TDABM), we demonstrate that the performance of random forest and logit regression models varies according to return trajectory. A novel use of TDABM as a forecast model shows that mapping historic return trajectories can also produce more accurate directional return forecasts. Our approach highlights how the predictability of BTC price change direction is dependent on return trajectories. Visualizing historic return trajectories when forming and evaluating return forecasts is imperative.

A topological approach for capturing high-order interactions in graph data with applications to anomaly detection in time-varying cryptocurrency transaction graphs

Umar Islambekov, Hasani Pathirana, Omid Khormali, Cßneyt Gßrcan Akçora ¡ 5 authors

Time-varying graphs are increasingly common in financial, social and biological data analysis applications. Feature extraction that efficiently encodes the complex structure of sparse, multi-layered, dynamic graphs presents computational and methodological challenges. In the past decade, topological data analysis has become a popular method of studying the shape of data. This is achieved by building an increasing sequence of simplicial complexes (called filtration) indexed by a scale parameter on top of the data to keep track of topological changes along with the filtration. This multi-scale summary, called persistence diagram (PD), is often vectorized to be used in machine learning algorithms. This paper introduces a topological approach to extract information on higher-order interactions encoded in persistence diagrams from graph data. Our framework has two main steps: first, we convert the graph into a higher-dimensional simplicial complex by adding structures such as triangles, tetrahedrons etc., and compute a PD using the so-called lower-star filtration which utilizes quantitative node attributes. Then, we vectorize the PD by averaging the associated Betti function over successive scale values of a one-dimensional grid using integration. A notable aspect of our procedure is that it avoids embedding a graph into a metric space. We show that the proposed vectorization summary is robust against input noise with respect to the $ L_1 $ 1-Wasserstein distance. In simulation studies, the proposed approach leads to improved change point detection rates and outperforms one of the state-of-the-art methods for anomaly detection in time-varying graphs. In real data application, our approach leads to up to a 20% gain in anomalous price prediction in the Ethereum cryptocurrency transaction network.

Mild explocivity, persistent homology and cryptocurrencies' bubbles: An empirical exercise

Stelios Arvanitis, Michalis Detsis

&lt;abstract&gt;&lt;p&gt;An empirical investigation was held regarding whether topological properties associated with point clouds formed by cryptocurrencies' prices could contain information on (locally) explosive dynamics of the processes involved. Those dynamics are associated with financial bubbles. The Phillips, Shi and Yu &lt;sup&gt;[&lt;xref ref-type="bibr" rid="b33"&gt;33&lt;/xref&gt;,&lt;xref ref-type="bibr" rid="b34"&gt;34&lt;/xref&gt;]&lt;/sup&gt; (PSY) timestamping method as well as notions associated with the Topological Data Analysis (TDA) like persistent simplicial homology and landscapes were employed on a dataset consisting of the time series of daily closing prices of the Bitcoin, Ethereum, Ripple and Litecoin. The note provides some empirical evidence that TDA could be useful in detecting and timestamping financial bubbles. If robust, such an empirical conclusion opens some interesting paths of further research.&lt;/p&gt;&lt;/abstract&gt;

Who is Who on Ethereum? Account Labeling Using Heterophilic Graph Convolutional Network

Dan Lin, Jiajing Wu, Tao Huang, Kaixin Lin ¡ 5 authors

To combat cybercrimes and maintain financial security for the blockchain ecosystem, “know your customer” (KYC) is an essential and also challenging process due to the pseudonymity nature of blockchain technology. To unlock the potential of KYC on blockchain-based platforms like Ethereum, account labeling is a powerful means which can de-anonymize addresses by mining public transaction records. Existing studies on account labeling are mainly conducted via machine learning (ML) methods fed with hand-crafted features or graph neural networks based on the modeled transaction network. However, ML approaches based on hand-crafted features ignore the global interaction information between accounts, making it easy for criminals to evade detection. Moreover, the performance of traditional GCN methods when applied to Ethereum transaction network encounters limitations due to label sparsity, network heterophily, and large network size of the transaction network. In this article, we first analyze Ethereum accounts involved in typical businesses, in terms of both account and topological features. Then based on the analytical results, we propose a novel GCN method named know-your-customer graph convolutional network (KYC-GCN) which contains two key designs: 1) multihop aggregators and importance-based sampling are designed to tackle the dilemma between accuracy and efficiency. 2) GCN architecture is improved to explicitly capture local and more global information. Experimental results on a realistic Ethereum dataset show that the proposed KYC-GCN (90.2% accuracy, 86.2% Marco-F1) achieves state-of-the-art classification performance, and results on six benchmarks demonstrate that it yields great performance under homophily and heterophily.

A fast topological approach for predicting anomalies in time-varying graphs

Umar Islambekov, Hasani Pathirana, Omid Khormali, Cßneyt Gßrcan Akçora ¡ 5 authors

Large time-varying graphs are increasingly common in financial, social and biological settings. Feature extraction that efficiently encodes the complex structure of sparse, multi-layered, dynamic graphs presents computational and methodological challenges. In the past decade, a persistence diagram (PD) from topological data analysis (TDA) has become a popular descriptor of shape of data with a well-defined distance between points. However, applications of TDA to graphs, where there is no intrinsic concept of distance between the nodes, remain largely unexplored. This paper addresses this gap in the literature by introducing a computationally efficient framework to extract shape information from graph data. Our framework has two main steps: first, we compute a PD using the so-called lower-star filtration which utilizes quantitative node attributes, and then vectorize it by averaging the associated Betti function over successive scale values on a one-dimensional grid. Our approach avoids embedding a graph into a metric space and has stability properties against input noise. In simulation studies, we show that the proposed vector summary leads to improved change point detection rate in time-varying graphs. In a real data application, our approach provides up to 22% gain in anomalous price prediction for the Ethereum cryptocurrency transaction networks.

Why Topological Data Analysis Detects Financial Bubbles?

Samuel W. Akingbade, Marian Gidea, Matteo Manzi, Vahid Nateghi

We present a heuristic argument for the propensity of Topological Data Analysis (TDA) to detect early warning signals of critical transitions in financial time series. Our argument is based on the Log-Periodic Power Law Singularity (LPPLS) model, which characterizes financial bubbles as super-exponential growth (or decay) of an asset price superimposed with oscillations increasing in frequency and decreasing in amplitude when approaching a critical transition (tipping point). We show that whenever the LPPLS model is fitting with the data, TDA generates early warning signals. As an application, we illustrate this approach on a sample of positive and negative bubbles in the Bitcoin historical price.

Ethereum Price Prediction using Topological Data Analysis

Samia Mohamed Hafez, Mustafa El Nainay, Mohamed S. Abougabal, Ahmed E. Kosba

The popularity of cryptocurrencies is increasing, as they have become an economy of their own, due to the observed returns of investments in cryptocurrencies and digital assets. This led to an increasing interest in the prediction of their prices over the past few years. Ethereum is one of the most popular cryptocurrencies that has witnessed an increase of prices since 2015 while having the second largest market cap. Ethereum is a decentralized platform that incorporates several interactions, not limited to asset trading only; it is also a platform of smart contracts execution and token trading. In this work, we aim at reflecting the interactions perceived in the Ethereum network on Ether prices using Topological Data Analysis (TDA). We introduce a method to extract the TDA features of the indicators of different interaction networks; traded volumes, smart contracts, and transactions between accounts. We conducted an analysis of the effect of using TDA features on Ether price prediction and extended our method to predict the prices of eight Ethereum tokens. Our method resulted in 0.75%, 4.9%, and 13.75% MAPE in hourly, daily, and weekly forecasts respectively, outperforming the previously reported results.
