I recently applied both Sobol and SHAP to my model to get the most impactful feature, because I thought using two methods could be more convincing. However, I got inconsistent importance scores from the two methods. Consequently, I have to figure out what is wrong; life is hard.

  1. Test on a simple dataset(housing prices) to check if I use the methods correctly
  2. Searching for theoretical explanation according to the result
