Abstract
Systems and methods for generating and using trained logit models using weight-of-evidence (WOE) based processes are disclosed. A training data set including sets of variables and a classification of each set in the sets of variables is received. The classification includes one of at least two potential classifications. A WOE feature set is generated by applying a binning process to each variable in the set of variables to generate one or more WOE transformations and applying the one or more WOE transformations to a corresponding variable in the set of variables. A trained logistic regression model is generated by applying an iterative training process based on the WOE feature set. The trained logistic regression model is configured to classify each set of variables. Production data sets are classified into one of the at least two potential classifications using the WOE transformations and the trained logistic regression model.
