Webb7 nov. 2024 · Since I published the article “Explain Your Model with the SHAP Values” which was built on a random forest tree, readers have been asking if there is a universal SHAP Explainer for any ML algorithm — either tree-based or non-tree-based algorithms. That’s exactly what the KernelExplainer, a model-agnostic method, is designed to do. WebbCatBoost claims to have great defaults and we’ve seen it to be quite successful on two different datasets.
