Webb28 feb. 2024 · Interpretable Machine Learning is a comprehensive guide to making machine learning models interpretable "Pretty convinced this is the best book out there on the subject " – Brian Lewis, Data Scientist at Cornerstone Research Summary This book covers a range of interpretability methods, from inherently interpretable models to … WebbWe used the force_plot method of SHAP to obtain the plot. Unfortunately, since we don’t have an explanation of what each feature means, we can’t interpret the results we got. However, in a business use case, it is noted in [1] that the feedback obtained from the domain experts about the explanations for the anomalies was positive.

Webb26 sep. 2024 · SHAP and Shapely Values are based on the foundation of Game Theory. Shapely values guarantee that the prediction is fairly distributed across different features (variables). SHAP can compute the global interpretation by computing the Shapely values for a whole dataset and combine them. Webb5 okt. 2024 · SHAP summary plots provide an overview of which features are more important for the model.

WebbBy default a SHAP bar plot will take the mean absolute value of each feature over all the instances (rows) of the dataset. [60]: shap.plots.bar(shap_values) But the mean absolute value is not the only way to create a global measure of feature importance, we can use any number of transforms. Webbshapr supports computation of Shapley values with any predictive model which takes a set of numeric features and produces a numeric outcome. Note that the ctree method takes both numeric and categorical variables. Check under “Advanced usage” for an example of how this can be done.
