Shap categoricals
WebbThe basic idea is create dataframe with category feature type, and tell XGBoost to use it by setting the enable_categorical parameter. See Getting started with categorical data for a … WebbLike the LIME package, SHAP works with explainer objects to calculate the results, and provides us with 3 main explainer categories: shap.TreeExplainer. shap.DeepExplainer. shap.KernelExplainer. The first 2 are model specific algorithms, which makes use of the model architecture for optimizations to compute exact SHAP values as mentioned above.

Note that as we increase the threshold we constrain the ordering of the ... WebbIn this example, we show how the KernelSHAP method can be used for tabular data, which contains both numerical (continuous) and categorical attributes. Using a logistic regression model fitted to the Adult dataset, we examine the performance of the KernelSHAP algorithm against the exact shap values. We investigate the effect of the background ...

During cell therapy 110,000 cells (SHAP 3.8) were injected into unilateral osteonecrosis (SHAP 2.3). The total SHAP (22) value is > 16, and this patient should have more than 15-year collapse-free survival with cell therapy. WebbSimple dependence plot ¶. 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 ...
