Nice work again, Avi!

Christoph Molnar also wrote about it in his interpretable machine learning model book, it is called "global surrogate model": https://christophm.github.io/interpretable-ml-book/global.html

Thanks for sharing this, Marcell. When they talk about Approximation model, I find this idea to be very similar to knowledge distillation :)

Thanks again for sharing, and appreciating the work :)

This is a great idea! I'm curious how mathmatically sound this would be to create a "global surrogate model" for xgboost or other boosted trees models?

Intuitively it seems very similar.

Any chance you have sample code in R?
