Laurent Lepage developed a built-in ShapExplainer function for the apache/systemds repository, enabling computation of Shapley values for feature attribution in machine learning models. He implemented supporting utilities for mask preparation, background data sampling, mask application, and final value computation, all designed to enhance model interpretability and support explainable AI workflows. The work was carried out using DML and Java, with a focus on algorithm implementation and data science principles. Laurent ensured robustness by adding comprehensive unit and component tests, resulting in a well-structured feature that integrates seamlessly into SystemDS and provides reliable, data-driven insights for end users.

October 2024 monthly summary for Apache SystemDS: Delivered a built-in ShapExplainer function to compute Shapley values for feature attribution in SystemDS.
