PSG-Nav: Probabilistic Scene Graph Navigation via Multiverse Decision Making
arXiv CS.AI

ArXi:2606.01313v1 Announce Type: cross Open-vocabulary navigation requires embodied agents to manage significant perception uncertainty stemming from semantic ambiguity and model errors. However, most existing works settle for local optimal deterministic approaches, depriving complex navigation decision-making over multiple composite possibilities that are critical for globally better solutions.
