FGRF Version 2.0

Version 2 represents a major evolution from the original proof-of-concept. It reframes FGRF from a direct optimizer into a structural integrity probe for neural networks.

What's New

  • Numerical Stability: Hybrid ODE integrator (explicit with adaptive damping + implicit midpoint fallback)
  • High-Fidelity Math: Finite-difference topological complexity and participation-ratio Hausdorff dimension estimator
  • Rigorous Evaluation: Held-out evaluation with full ablation suite (full, plain_gd, no_thermo, no_fractal, random)
  • Diagnostic Utility: Near-zero updates on highly optimized models like Qwen2.5-0.5B

New Files

  • fgrf_multi_model_v2.py, fgrf_multi_input_v2.py — V2 core scripts
  • examples/run_*_v2.py — V2 example scripts for GPT-2 and Qwen2.5
  • paper/fgrf_v2_paper.pdf — V2 research paper
  • results/V2/ — V2 evaluation results
