Shap summary_plot arguments
WebbSHAP summary plot shows the contribution of the features for each instance (row of data). The sum of the feature contributions and the bias term is equal to the raw prediction of the model, i.e., prediction before applying inverse link function. h2o.shap_summary_plot ( model , newdata , columns = NULL , top_n_features = 20 , sample_size = 1000 ) WebbSHAP scores only ever use the output of your models .predict () function, features themselves are not used except as arguments to .predict (). Since XGB can handle NaNs they will not give any issues when evaluating SHAP values. NaN entries should show up as grey dots in the SHAP beeswarm plot. What makes you say that the summary plot is ...

Summary plots are easy-to-read visualizations which bring the whole data to a single plot. All of the features are listed in y-axis in the rank order, the top one being the most contributor to the predictions and the bottom one being the least or zero-contributor. Shap values are provided in the x-axis.
Webb2.3.8 Summary Plot¶ The summary plot shows the beeswarm plot showing shap values distribution for all features of data. We can also show the relationship between the shap values and the original values of all features. We can generate summary plot using summary_plot() method.

Let’s see how we can do that: shap.summary_plot(shap_values, features=X_train, feature_names=X_train.columns) We get the above plot by putting …
WebbLet’s take a look at the first row of the summary_plot. If a Kickstarter project owner set the goal high (pink dots) the model output was likely 0 (negative SHAP value, not successful). It totally makes sense: if you set the bar for the money goal too high, you cannot reach it.
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.
