PSG-Nav: Probabilistic Scene Graph Navigation via Multiverse Decision Making
Researchers introduce PSG-Nav, a novel navigation system that uses probabilistic scene graphs to help AI agents navigate complex environments while accounting for perception uncertainty. The system achieves state-of-the-art results on three major benchmarks by employing multiverse decision-making and an evidential calibrator to reduce false positives in open-vocabulary navigation tasks.
