WebDec 24, 2024 · 1 I have a multiclass classification task where the target has 11 different classes. The target to classify is the Length of Stay in a hospital and the target classes are in different bins, for example, 1-10, 11-20, 21-30 and so. So far I have tried Neural Net for my task but I am not getting a good performance.

Monotonic WOE Binning Algorithm for Credit Scoring

WebMay 8, 2024 · For the purpose of this project, I converted the output to a binary output where each wine is either “good quality” (a score of 7 or higher) or not (a score below 7). The quality of a wine is determined by 11 input variables: Fixed acidity Volatile acidity Citric acid Residual sugar Chlorides Free sulfur dioxide Total sulfur dioxide Density pH WebHow to check correct binning with WOE 1. The WOE should be monotonic i.e. either growing or decreasing with the bins. You can plot WOE values and check linearity on the graph. 2. Perform the WOE transformation after binning. Next, we run logistic regression with 1 independent variable having WOE values. sma smc software
