WebbI'm wondering if there's any algorithm could do classification and regression at the same time. For example, I'd like to let the algorithm learn a classifier, and at the same time within each label, it also learns a continuous target. Thus, for each training example, it has a categorical label and a continuous value.. I could train a classifier first, and then train a … WebbThe method has the ability to perform both classification and regression prediction. Random forests are an improved extension on classification and regression trees (CART) (Liaw and Weiner, 2002) with respect to instability and accuracy. Specifically, random forests remain relatively stable with changes in data due to the combination of many trees.
