MUFASA: Fast and Accurate Multivariate Time-Series Clustering
Summary: MUFASA extends k-Shape with SBD-D for global cross-channel alignment and a joint, efficient centroid update, capturing multivariate dependencies without cubic costs. It matches elastic-distance accuracy 2–4 orders faster and outperforms scalable and deep baselines. (summarized by gpt-5.6-luna on Jul 26 2026)
