What Spatial Memory Must Store: Occlusion as the Test for Language-Agent Memory

arXiv cs.AI · 2026-06-10 Cached

This paper investigates whether spatial geometry improves language-agent memory recall, demonstrating that geometry must lead recall over recency and importance, and that a ray-tracing visibility predicate is crucial for occlusion handling in 3D voxel worlds.

Geometric Phase Transition Enables Extreme Hippocampal Memory Capacity

Hugging Face Daily Papers · 2026-05-16 Cached

This paper reveals that superior spatial memory in food-caching birds arises from a geometric phase transition in hippocampal population activity, from disorganized 'mist' to crystalline collective coding, enabling over 100-fold higher capacity.
