Tsfresh – Automatic extraction of relevant features from time series

Given the first pass seems often to be picking some standardish stuff to look for it sounds like this could be useful even with minimally "smart" feature selection.

> To avoid extracting irrelevant features, the TSFRESH package has a built-in filtering procedure. This filtering procedure evaluates the explaining power and importance of each characteristic for the regression or classification tasks at hand.

> It is based on the well developed theory of hypothesis testing and uses a multiple test procedure. As a result the filtering process mathematically controls the percentage of irrelevant extracted features.

Here's the paper on this: https://arxiv.org/abs/1610.07717

It seems that the relevance of the features is somewhat tunable based on the p-value you choose for the statistical tests. (Every feature selection algorithm I can think of has some tunable parameter, although the information theoretic ones just depend on the length of features you're willing to consider.)

what for? for the feature extraction part?
