Examples

Contents:

• Example 1: Interaction Indices for a Gradient Boosted Tree on the Folktables Income data set
  • Load the data
  • Train the classifier
  • Define the value function
  • Compute n-Shapley Values
  • Let’s compare this to the Shapley Values from the shap package
  • Now, let us repeat this exercise with the the Shapley Taylor interaction index
  • Now, the same exercise for Faith-Shap interaction index
• Example 2: An Illustration of Recovery for a Function with Variable Interactions
  • The function
  • This function consists mostly of variable interaction of order 2, so the partial dependence plots of Shapley Values don’t have any clear structure
  • 2-Shapley Values provide a representation of the function as a GAM
• Example 3: Custom value functions
  • These examples are from section 5.1 of the Faith-Shap paper: https://arxiv.org/abs/2203.00870
