Shapley value calculation example
Webb11 apr. 2024 · We introduce Shapley value for measuring neuron's contribution to model prediction changes due to small perturbations. Then we identify neurons with larger Shapley value as excitable neurons. We verified that excitable neurons are closely associated with various potential defects triggering incorrect model behaviors. • WebbSo I used an example from SHAP's github notebook, Census income classification with LightGBM. Right after I trained the lightgbm model, I applied explainer.shap_values () on each row of the test set individually. By using force_plot (), it yields the base value, model output value, and the contributions of features, as shown below:
