OptBinning: The Python Optimal Binning library ¶ Optimal binning with binary target Optimal binning with continuous target Optimal binning with multiclass target Binning process Binning tables Utilities The optimal binning is the optimal discretization of a variable into bins given a discrete or continuous numeric target. In this paper, we carry out a statistical analysis of the effect of bin selection for MTM. The optimal binning allows you to transform continuous variables into an ordered set of bins. use several algorithms to fit on training data, predict on validation data Mar 12, 2015 · When optimal equal width binning is not used the area under the ROC curve is more than 85% for both the Naive Bayes and Neural Network classifiers. The woe transformation is a piecewise transformation that is linear to the log odds. .
