WebTime series can be clustered based on three criteria: having similar values across time, tending to increase and decrease at the same time, and having similar repeating patterns. The output of this tool is a 2D map displaying each location in the cube symbolized by cluster membership and messages.

WebTime series clustering algorithms can be broadly classified into two approaches: raw-data-based methods and feature-based methods [19]. 2.1 Raw-data-based methods Raw-data-based methods mainly modify the distance function to adapt to the time series characteristics (e.g., scaling and distortion). Webtsfresh. This is the documentation of tsfresh. tsfresh is a python package. It automatically calculates a large number of time series characteristics, the so called features. Further the package contains methods to evaluate the explaining power and importance of such characteristics for regression or classification tasks.

WebTime Series Clustering is an unsupervised data mining technique for organizing data points into groups based on their similarity. The objective is to maximize data similarity within clusters and minimize it across clusters. Time-series clustering is often used as a subroutine of other more complex algorithms and is employed as a standard tool in data …
