Aiming at the problem that the kNN algorithm is susceptible to the choice of k-nearest neighbors and the method of class judgment, this paper propose a kNN algorithm based on class contribution and feature weighting called DCT-kNN. Firstly, using traditional kNN to calculate accuarcy of original dat...
