What Spatial Memory Must Store: Occlusion as the Test for Language-Agent Memory
Quick Answer
The study evaluates language-agent memory systems, revealing that geometry-led weighting outperforms traditional methods in spatial memory recall, achieving a significant performance delta of +0.3208 over a baseline.
Quick Take
The study evaluates language- systems, revealing that geometry-led weighting outperforms traditional methods in spatial memory recall, achieving a significant performance delta of +0.3208 over a baseline. This research isolates the essential elements of spatial memory, paving the way for future studies on multi-world memory systems.
Key Points
- Traditional memory-palace methods can hinder performance, showing a mean Delta-Hit@5 of -0.0375.
- Geometry-led weighting achieved a significant improvement with a Delta-Hit@5 of +0.3208.
- The study highlights the importance of isolating spatial memory components for effective recall.
- Future work will involve a full human-authored multi-world study with blind raters.

From source RSS / original summaryarXiv:2606. 10299v1 Announce Type: new Abstract: Language-agent "memory palace" systems anchor each memory to a world coordinate, on the intuition that geometry adds something text cannot. We make that intuition testable and report three results. First, the memory-palace default of folding spatial proximity into a linear blend beside recency and importance does not help and can hurt: in a pre-registered recall experiment the shipped blend fails its own frozen test (mean Delta-Hit@5 -0. 0375, Wilcoxon p=0.
306), sitting at a position-blind baseline, while a geometry-led weighting wins decisively (+0. 3208, p0. 000, pooled exact McNemar p=2. 5x10^-29), a run that surfaced and fixed a real relay anchor defect. We concede that occlusion-needs-geometry is near-tautological; the contribution is the measurement and isolation, separating what spatial memory must store from how it is read.
These pilots power a frozen confirmatory study (SPMEM-ZERO-REAL-PREREG-v1); the full human-authored multi-world study with blind raters remains future work.
