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. WebbThe force plot above the text is designed to provide an overview of how all the parts of the text combine to produce the model’s output. See the `force plot <>`__ notebook for more details, but the general structure of the plot is positive red features “pushing” the model output higher while negative blue features “push” the model output lower.
