摘要：
Recently, several variants of random forest have been derived for the classification problems, among which the rotation forest is an important type to improve the model's accuracy. In this article, we proposed a simple and effective variation of rotation forest, which the canonical partial least squares algorithm is employed to rotate the variable space of tree and then all the trees are combined being a "forest." Results of an experiment on a sample of 20 benchmark datasets show our method has better prediction performance comparing with random forest and rotation forest.
