In the real wo rld, most of the applications are inherently dynamic in nature i.e. their underlying data distribution changes with time.As a result, the concept drifts occur very frequently in the data stream.Concept drifts in data stream increase the challenges in learning as well, it also significantly decreases the accuracy of the classifier.However, recently many algorith ms have been proposed that exclusively designed for data stream mining while considering drift ing concept in the data stream.This paper presents an empirical evaluation of these algorith ms on datasets having four possible types of concept drifts namely; sudden, gradual, incremental, and recurring drifts.
