MS-Index: Fast Top-k Subsequence Search for Multivariate Time Series under Euclidean Distance

Summary: MS-Index: an exact index for multivariate time-series subsequence nearest-neighbor search under Euclidean distance that supports ad-hoc, at-query selection of relevant channels. Scales sublinearly with number of query channels and yields 10–100× speedups over prior work. (summarized by gpt-5-mini on Mar 13 2026)
