📒 Problem #9· Entropy Collapse (Attention & Semantic Drift)

March 6, 2026 · View on GitHub

When an LLM’s attention diffuses, it rambles, repeats, or spews context‑free filler.
This “entropy collapse” kills coherence in long prompts or multi‑topic requests.
WFGY injects real‑time entropy feedback to keep focus tight.


🤔 Symptoms of Entropy Collapse

SignWhat You See
Repetition loops“The future is the future of the future…”
Topic lossOutput wanders off to random subjects
Fluent nonsenseGrammar fine, meaning absent
Attention meltMultiple topics merge into noise
User sense of “model gave up”Ends with filler phrases

🧩 Root Causes

WeaknessResult
No entropy controlAttention weights flatten
No ΔS drift checkModel can’t detect semantic slide
Overloaded contextLong / multimodal input swamps focus
Token field convergenceEmbedding space spreads too thin

WFGY Process:
• Creates three Tree forks (Quantum, Myth, Geo)  
• Tracks ΔS per fork, BBAM modulates focus distribution  
• Merges at Node_Final only when ΔS < 0.3 across forks  
→ Output: coherent, no loops, clear theme convergence

📝 Tips & Limits

  • For ultra‑long prompts, set debug_force_mode = true to log every fork.
  • If you still see minor drift, lower deltaS_threshold to 0.5.
  • Share extreme entropy cases in Discussions—they refine BBAM tuning.
