Webb27 dec. 2024 · Now, we have SHAP values for every sample, instead of just samples in one test split of the data, and we can plot these easily using the SHAP library. We first just have to update the index of X to match the order in which they appear in each test set of each fold, otherwise, the color-coded feature values will be all wrong. Notice that we re-order X … Webb19 dec. 2024 · SHAP is the most powerful Python package for understanding and debugging your models. It can tell us how each model feature has contributed to an … WebbSometimes it is helpful to transform the SHAP values before we plots them. Below we plot the absolute value and fix the color to be red. This creates a richer parallel to the standard shap_values.abs.mean(0) bar plot, since the bar plot just plots the mean value of the dots in the beeswarm plot. au から povo sim ロック 解除 必要
