WebApr 14, 2024 · We also used the tsfresh package (Christ et al., 2024) to automatically calculate derived static features from the underlying time-series data, resulting in 916 features from 20 low frequency signals and 12,853 features from 6 high frequency signals. Highly correlated features were removed when Pearson correlations were greater than 0.95. WebSep 2, 2024 · 3. Tsfresh. Tsfresh is an open-source Python package for time-series and sequential data feature engineering. The package allows us to create thousands of new features with few lines. Moreover, the package is compatible with the Scikit-Learn method, which enables us to incorporate the package into the pipeline.
