Webb28 mars 2024 · The summary plot (a sina plot) uses a long format data of SHAP values. The SHAP values could be obtained from either a XGBoost/LightGBM model or a SHAP value matrix using shap.values. So this summary plot function normally follows the long format dataset obtained using shap.values. If you want to start with a model and data_X, … WebbSHAP value (also, x-axis) is in the same unit as the output value (log-odds, output by GradientBoosting model in this example) The y-axis lists the model's features.
