> Univariate feature selection works by selecting the best features based on univariate statistical tests. False Positive Rate (FPR) is a popular univariate statistical test for feature selection. Is it necessary to add a chiSquare Selector based on False Positive Rate (FPR) test, like it is implemented in scikit-learn.
