QuadraSHAP offers stable, scalable Shapley values for product games

Researchers have developed QuadraSHAP, a novel method for efficiently calculating Shapley values in product games, which are common in machine learning explainability. The technique reduces the complex calculation to a single integral, allowing for exact or near-exact approximations with a Gauss-Legendre quadrature scheme. This approach is significantly faster and more numerically stable than existing methods, even for a large number of features. AI
