Warning: impurity-based feature … WebTo come back to your question: while both MAE/ MSE are performance measures, they are being used at two different stages of a modeling process and might not be related. So, while it makes sense to evaluate your final model on MAE as you would be judged on it, you can choose any of MAE/ MSE for criterion (i.e. for RandomForest ) depending on ...

The default values for the parameters controlling the size of the trees (e.g. max_depth, min_samples_leaf, etc.) lead to fully grown and unpruned trees which can potentially be very large on some data sets.To reduce memory consumption, the complexity and size of the trees should be controlled by setting those parameter values.
