Hi, I am a novice here and am not aware of the exact source for implementation. Probably one of the core devs can answer it. But to my knowledge, it implements an optimised version of CART. The information regarding the algorithms and complexity can be found in http://scikit-learn.org/stable/modules/tree.html#tree-algorithms-id3-c4-5-c5-0-and-cart . Hope it helps to some extent.
Cheers, Maniteja. _________________________________________ scikit-learn mailing list [email protected] https://mail.python.org/mailman/listinfo/scikit-learn
