I have gone through the recent white paper on model explainability.

I couldnt find the feature weight calculating operators like:  Shap, Shapley.  I am using education studio version 9.9.003
can you guide me how to find them. thanks.

    Hi , thanks for your reply.  I m able to see three operators in interpretations extension:  1.  Generate interpretations, 2. Generate neighbourhood,  3.  Generate univariate interpretations.   I think this belongs to 'generate interpretations'.

    thanks.

    Hi,

    the interpretations extension is working fine with GBM but not with XGBoost (Type / Class issue, it expects AbstractModel). Are there plans in the nearby future to support XGBoost as well? It would allow us to interpret the shortlisted models using the same component / methods (Lime, KernelSHAP, Shapley). The "Explain Predictions" extension works fine and is useful, yet a different algorithm. The results wouldn't be 1:1 compareable.

    Cheers
