WebMay 27, 2024 · You are welcome :-) Yes, tsfresh needs all the time-series to be "stacked up as a single time series" and separated by an id (therefore the column). That is because if you want to do multivariate time-series analysis you can still use a Matrix / 2D-dataframe. You can ignore the index btw. – Webtsfresh.feature_selection.relevance module. Contains a feature selection method that evaluates the importance of the different extracted features. To do so, for every feature the influence on the target is evaluated by an univariate tests and the p-Value is calculated. The methods that calculate the p-values are called feature selectors.
WebApr 2, 2024 · Manual feature extraction is a time consuming and tedious task. In most cases it involves thinking about possible features, writing feature calculator code, consulting library API documentation and drinking a lot of coffee. And in the end, most of the features will not make it to the production machine learning pipeline anyways. Entering tsfresh
