Correspondences as Decisions: JevNexus for Decision-Centric Schema Matching
Runze Li, Hanchen Wang, Ying Zhang +1
Schema matching increasingly uses generative language models to rerank retrieved column candidates, although the underlying task is a bounded correspondence decision. We present Je…
SignScene: Visual Sign Grounding for Mapless Navigation
Nicky Zimmerman, Joel Loo, Benjamin Koh +2
Navigational signs enable humans to navigate unfamiliar environments without maps. This work studies how robots can similarly exploit signs for mapless navigation in the open world…
SignLoc: Robust Localization using Navigation Signs and Public Maps
Nicky Zimmerman, Joel Loo, Ayush Agrawal +1
Navigation signs and maps, such as floor plans and street maps, are widely available and serve as ubiquitous aids for way-finding in human environments. Yet, they are rarely used b…
Sign Language: Towards Sign Understanding for Robot Autonomy
Ayush Agrawal, Joel Loo, Nicky Zimmerman +1
Navigational signs are common aids for human wayfinding and scene understanding, but are underutilized by robots. We argue that they benefit robot navigation and scene understandin…
Human-Inspired Long-Term Indoor Localization in Human-Oriented Environment
Nicky Zimmerman, Matteo Sodano
Lifelong localization is crucial for enabling the autonomy of service robots. In this paper, we present an overview of our past research on long-term localization and mapping, expl…
