WebbSentiment Analysis with Logistic Regression ¶ This gives a simple example of explaining a linear logistic regression sentiment analysis model using shap. Note that with a linear model the SHAP value for feature i for the prediction f ( x) (assuming feature independence) is just ϕ i = β i ⋅ ( x i − E [ x i]). WebbThese SHAP values are generated for each feature of data and generally show how much it impacts prediction. SHAP has many explainer objects which use different approaches to generate SHAP values based on the algorithm used behind them. We have listed them later giving a few line explanations about them. 3. How to Interpret Predictions using SHAP? WebbRight after I trained the lightgbm model, I applied explainer.shap_values () on each row of the test set individually. By using force_plot (), it yields the base value, model output value, and the contributions of features, as shown below: My understanding is that the base value is derived when the model has no features. darty famille
