CoShap: A Scalable Coalition Growth Approach to Shapley Value Approximation

Summary: CoShap approximates Shapley values via layer-wise coalition growth, reusing utilities to avoid Monte Carlo redundancy, followed by variance-aware feature evaluation. Dynamic cross-phase budgeting provides (ε,δ) guarantees, delivering up to 7.15× speedup and 76.84% lower error. (summarized by gpt-5.6-luna on Jul 26 2026)
