Lightgbm plot_importance
WebJan 24, 2024 · I intend to use SHAP analysis to identify how each feature contributes to each individual prediction and possibly identify individual predictions that are anomalous. For instance, if the individual prediction's top (+/-) contributing features are vastly different from that of the model's feature importance, then this prediction is less trustworthy.
