WebJan 6, 2015 · 5 Answers. Do not use k-means for timeseries. DTW is not minimized by the mean; k-means may not converge and even if it converges it will not yield a very good result. The mean is an least-squares estimator on the coordinates. It minimizes variance, not arbitrary distances, and k-means is designed for minimizing variance, not arbitrary … WebFigure 1: k-means clustering (k = 3) using di erent base metrics.
