WebMar 23, 2024 · We introduced also the Recursive Feature Addition approach as a valuable alternative to the standard Recursive Feature Elimination. Few know that, like most data-driven algorithms, also feature selection tends to be inaccurate over time. So the filtering process needs to be repeated with fresh data to capture the new patterns. Webfeatures and continuous features, the cross contingency test including two s is coefficient carried out to obtain the correlation of features and the features subset with s strong a correlation. Based on the features subset, a recursive feature addition algorithm is proposed to select the optimal features subset with high average recall rate.
