WHY THE BRAIN CONSOLIDATES: PREDICTIVE FORGETTING FOR OPTIMAL GENERALISATION
Executive Impact Summary
This research paper proposes a novel computational theory for memory consolidation, termed 'predictive forgetting.' Instead of merely stabilizing memories, the brain actively compresses stored representations by selectively discarding information that does not predict future outcomes. This process, which occurs offline (e.g., during sleep), is crucial for optimizing generalisation and preventing overfitting in high-capacity neocortical networks. The framework integrates system consolidation, representational drift, memory semanticisation, and continual learning under a single objective. It provides quantitative predictions for changes in neural representational geometry and offers principled solutions for challenges in AI, such as catastrophic forgetting and context window limitations in large language models (LLMs).

| Input Dependency | High I(X;Z) | Low I(X;Z|Y) |
| Generalisation | Prone to Overfitting | Optimized Generalisation |
| Mechanism | Single-Pass Encoding | Iterative Refinement/Replay |
| Capacity Dependency | Less critical in low capacity | Crucial for high capacity systems |
LLM Cache Consolidation
The study demonstrates that Transformer-based LLMs benefit from predictive forgetting by consolidating Key-Value (KV) cache entries. This process, analogous to neocortical semantic memory, reduces task-irrelevant information in the cache, improving attentional retrieval and generalisation. The mechanism involves hierarchical refinement, with early layers performing global normalisation and deep layers engaging in selective editing. This directly addresses computational constraints as context windows grow.
Key Highlight: Achieved significant reduction in generalisation gap in LLMs on complex reasoning tasks through KV cache consolidation.
