We propose a model-agnostic feature importance method based on SHapley Additive exPlanations (Lundberg and Lee 2017), to generate such explanations that can be viewed as its generalization.… Continue Reading Explaining Model Behavior Across Space and Time: Differential and Intertemporal Explanations
