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.

WebApr 1, 2024 · Tslearn module provides k-means methods with a variety of distance computation options. The first step of time series clustering is the same like on the regular k-means that the number of K has to be decided first. It’s nice to know the optimum number of K first despite the three different rainfall clusters we already aware of. Web1. In this plot, each subplot presents a cluster (you are doing k-means with k=3, hence you generate 3 clusters): in gray, time series assigned to the given cluster are represented. in red, the centroid (computed using DBA algorithm) is superimposed.
