CascadeForestClassifier object has no attribute decision_function #150
Description
I'm encountering an error when trying to evaluate the CascadeForestClassifier using cross-validation with multiple scoring metrics, including roc_auc. It seems that the issue arises because the CascadeForestClassifier does not have a decision_function method, which is required for calculating the roc_auc score. Tried also predict_proba method, but also did not work. Hope you can add this function in the next version. Thank you!
