A Universal Framework for Catastrophic Forgetting Solution in Artificial Intelligence: Topological Anchoring Across Vision and Genomics

Description

TOPO-2026: A Universal Framework for Catastrophic Forgetting Solution

Executive Summary

TOPO-2026 presents a definitive solution to the catastrophic forgetting problem in artificial intelligence through deterministic mathematical anchoring. Unlike probabilistic methods that offer statistical approximations, this framework provides mathematical guarantees against forgetting with O(1) memory complexity (67.5 KB).

Core Innovation

The Problem

Catastrophic forgetting occurs when neural networks sequentially learn new tasks and overwrite previously acquired knowledge—a fundamental barrier to lifelong learning systems since McCloskey and Cohen's 1989 characterization.

The Solution

Arithmetic Spectral Theory (AST) leverages prime-number anchors at critical boundary layers:

  • Prime anchors: [2, 3, 5, 7, 11, 13]
  • Safety constant: $\Lambda = 0.9785142874$ (provable spectral coverage)
  • Minimal interference: 0.00298% of vocabulary matrix (Gemma) / 0.000003% (Evo2)

The Topological Governor Mechanism

Three-step process during sequential task training:

  1. Snapshot Capture: Freezes prime-indexed embedding row states after first task
  2. Gradient Enforcement: Blocks gradient updates to anchored positions during backpropagation
  3. Anchor Restoration: Restores anchored rows to original values after optimizer steps
