Webb11 apr. 2024 · To put this concretely, I simulated the data below, where x1 and x2 are correlated (r=0.8), and where Y (the outcome) depends only on x1. A conventional GLM with all the features included correctly identifies x1 as the culprit factor and correctly yields an OR of ~1 for x2. However, examination of the importance scores using gain and … Webb24 juni 2024 · CatBoost has a special way of doing categorical splitting that (when used) essentially creates new features to split on that are not in the original set of input features. These features allow you to split whole groups of categories one way or the other.

WebbLike the LIME package, SHAP works with explainer objects to calculate the results, and provides us with three main explainer categories: shap.TreeExplainer; shap.DeepExplainer; shap.KernelExplainer The first two are model specific algorithms, which makes use of the model architecture for optimizations to compute exact SHAP values as mentioned ... Webb4 aug. 2024 · SHAP is a module for making a prediction by some machine learning models interpretable, where we can see which feature variables have an impact on the predicted value. In other words, it can calculate SHAP values, i.e., how much the predicted variable would be increased or decreased by a certain feature variable. Reference.

A dependence plot is a scatter plot that shows the effect a single feature has on the predictions made by the model. In this example the log-odds of making over 50k increases significantly between age 20 and 40. Each dot is a single prediction (row) from the dataset. The x-axis is the value of the feature (from the X ...
