29 Jan 2018 Time series clustering along with optimized techniques related to the Dynamic Time Warping distance and its corresponding lower bounds. Implementations of partitional, hierarchical, fuzzy, k-Shape and TADPole clustering are available. Functionality can be easily extended with custom distance measures

You would not want to "chose" the parameters but rather evaluate the result. Therefore, you need to chose a criterion for evaluation of clustering. You basically vary the parameters such as distance and k and then evaluate the clustering using a loss function. Generally there are two possibilities for
dtwclust package for the R statistical software is provided, showcasing how it can be used to evaluate many different time-series clustering procedures. Keywords: time-series, clustering, R, dynamic time warping, lower bound, cluster validity. 1. Introduction. Cluster analysis is a task which concerns itself with the creation of

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
