Shap plots explained
WebbSHAP (SHapley Additive exPlanations) is a game-theoretic approach to explain the output of any machine learning model. It connects optimal credit allocation with local explanations using the classic Shapley values from game theory and their related extensions [1], [2].

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.
