Webb8 dec. 2024 · Comparing the results: The two methods produce different but correlated results. Another way to summarize the differences is that if we sort and rank the Shapley values of each sample (from 1 to 6), the order would be different by about 0.75 ranks on average (e.g., in about 75% of the samples two adjacent features’ order is switched).
