The Robot Memory Learned Which Furniture Had Gone Stale
HitMem decays old scene knowledge and narrows relocation searches with semantic, spatial and temporal context.
Summary
HitMem decays old scene knowledge and narrows relocation searches with semantic, spatial and temporal context.
A lightweight topological graph records support relationships while continuous perception lowers the activity of stale memories. When an object has moved, a two-stage retriever combines another agent's trajectory constraints with class affinities to identify likely regions. On the authors' Dyna-THOR benchmark, the method improved relocation accuracy and reduced exploration cost; the paper also evaluates dynamic simulated environments rather than every real home.
Why it matters
