WebbThis notebook is designed to demonstrate (and so document) how to use the shap.plots.text function. It uses a distilled PyTorch BERT model from the transformers package to do sentiment analysis of IMDB movie reviews. Note that the prediction function we define takes a list of strings and returns a logit value for the positive class. [9]: WebbThis plot shows how the prediction changes during the decision process. In the y-axis we have the features ordered by importance as for the summary plot. In the x-axis we have the output of the model. Moving from the bottom of the plot to the top, SHAP values for each feature are added to the model’s base value.
