TN-SHAP-G: Graph-Structured Tensor Network Surrogates for Shapley Values and Interactions

Shapley values are a widely used tool for attributing importance and interactions among input variables in black-box models, but their computation involves a function defined over an exponentially large space of subsets. We propose TN-SHAP-G, a framework that exploits structure in graph-structured i…
