Do you mean C5.0 which is further development of C4.5 tree algorithm? If so, then the answer is no, it's not implemented in sklearn. Furthermore, according to wikipedia <https://en.wikipedia.org/wiki/C4.5_algorithm#Improvements_in_C5.0.2FSee5_algorithm>, C5.0 is a commercial product and (AFAIK) algorithm details were never published.
Though there's C50 package for R and GPL-licensed open source implementation of C5.0, I doubt it can be incorporated into scikit-learn because the later uses more permissive BSD license. Also, I doubt that it'd qualify the requirement <http://scikit-learn.org/stable/faq.html#can-i-add-this-new-algorithm-that-i-or-someone-else-just-published> to be included: > As a rule we only add well-established algorithms.
