Model explainability refers to the process of relating the prediction of a machine learning (ML) model to the input feature values of an instance in humanly understandable terms. This field is often referred to as explainable artificial intelligence (XAI). Amazon SageMaker Clarify is a feature of Amazon SageMaker that enables data scientists and ML engineers to explain the predictions of their ML models. It uses model agnostic methods like SHapely Additive exPlanations (SHAP) for feature attribution. Apart from supporting explanations for tabular data, Clarify also supports explainability for both computer vision (CV) and natural language processing (NLP) using the same SHAP algorithm.
In this post, we illustrate the use of Clarify for explaining NLP models. Specifically, we show how you can explain the predictions of a text classification model that has been trained using the SageMaker BlazingText algorithm. This helps you understand which parts or words of the text are
