New algorithm computes exact Shapley values for product-kernel methods

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PKeX-Shapley, a novel algorithm designed to compute exact Shapley values for product-kernel methods in machine learning. This new method leverages the multiplicative structure of product kernels to achieve quadratic time complexity in the number of features, significantly improving upon existing approximation-based approaches. The algorithm offers a parameter-free solution that requires no sampling or density estimation, and it can be extended to statistical analyses like Maximum Mean Discrepancy and Hilbert-Schmidt Independence Criterion.
