The traditional method about KNN is generally used Euclidean distance formula to measure the distance between the two samples.However,every attribute has different function in actual samples;the weighted Euclidean distance is usually chosen.This paper presents a calculation of weight that is weighted based on the characteristics of KNN algorithm.The results of the experiments on artificial datasets show that this algorithm can improve the accuracy of classification.
