k-Nearest Neighbors on Road Networks: A Journey in Experimentation and In-Memory Implementation
Summary: In-memory evaluation of kNN on road networks, comparing network distance with Euclidean proxies and reproducing state-of-the-art methods fairly. Revisits the discarded IER approach with a simple improvement, often achieving the best performance. (summarized by gpt-5-nano on Feb 09 2026)
