LOCATER: Cleaning WiFi Connectivity Datasets for Semantic Localization

Summary: LOCATER reframes semantic indoor localization as data cleaning: fix missing AP-device links across WiFi events and map devices to semantic subregions. Bootstrapped semi-supervised learning yields coarse localization, while probabilistic refinement achieves fine-grained, room-like accuracy. (summarized by gpt-5-nano on Feb 09 2026)
