HSGNav: Hypothesis Scene Graphs for Multi-Scale Lifelong Navigation under Object Relocation
Overview
This research presents HSGNav, a navigation system that separates persistent furniture entities from revisable surface-object hypotheses to handle object relocation and multi-scale search in lifelong home environments. The authors introduce FAROS-Bench to evaluate mid-episode memory invalidation and multi-scale goal finding, showing that HSGNav competes with prior methods on GOAT-Bench while substantially outperforming them on the new benchmark.
