@jeremy I have been involved in fitting and interpreting RF’s for 2 years and I absolutely love this course: it talks about problems I have encountered myself and I love learning your approaches. One small thing: the treeintrepreter method has been shown to be inconsistent in the following paper: https://arxiv.org/abs/1802.03888. This means that features that are actually unimportant can somehow end up being important and vice versa. I would recommend educating about https://github.com/slundberg/shap library instead that doesn’t have such property.
