WebbSHAP describes the following three desirable properties: 1) Local accuracy ˆf(x) = g(x ′) = ϕ0 + M ∑ j = 1ϕjx ′ j If you define ϕ0 = EX(ˆf(x))ϕ0 = EX( ^f (x)) and set all x ′ jx′ j to 1, this is the Shapley efficiency property. Only with a … WebbThis gives a simple example of explaining a linear logistic regression sentiment analysis model using shap. Note that with a linear model the SHAP value for feature i for the prediction f ( x) (assuming feature independence) is just ϕ i = β i ⋅ ( x i − E [ x i]). Since we are explaining a logistic regression model the units of the SHAP ...

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. By default, the features are ranked by mean magnitude of SHAP values in descending order, and number of top features to include in the plot is 20.
