基于相对熵的数据流概念漂移检测算法
A DATA FLOW CONCEPTUAL DRIFT DETECTION ALGORITHM BASED ON RELATIVE ENTROPY
摘要
Abstract
Aiming at the problem of concept drift in data stream,this paper proposed a conceptual drift detection algorithm based on relative entropy based on decision tree as a classifier.The proposed algorithm combined the accuracy and relative entropy of the classifier as a criterion for judging whether the data block was drilled or not.The method was verified by 5 data sets.The algorithm obtained the optimal result on the four data sets,and the suboptimal result was obtained on the other data set.The experimental results showed that this method not only detected the occurrence of concept drift effectively,but also improved the accuracy of the classifier.关键词
