Shapley value calculation example

WebbIntroduction by example ¶. Introduction by example. Shapley is a Python library for evaluating binary classifiers in a machine learning ensemble. The library consists of various methods to compute (approximate) the Shapley value of players (models) in weighted voting games (ensemble games) - a class of transferable utility cooperative games. Webb11 apr. 2024 · It uses the Shapley values to measure each feature’s impact on the machine learning prediction model. Shapley values are defined as the (weighted) average of marginal contributions. It is characterized by the impact of feature value on the prediction across all possible feature coalitions. The Shapley value for an instance x is defined as ...

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:
