STUMPY is a powerful and scalable library that efficiently computes something called

the matrix profile, which can be used for a variety of

time series data mining tasks such as: pattern/motif

(approximately repeated subsequences within a longer time series) discovery,

anomaly/novelty (discord) discovery,

shapelet discovery,

semantic segmentation,

density estimation,

time series chains (temporally ordered set of subsequence patterns),

and more!
