Adaptive Method for Handling Local Concept Drift of Data Streams Classification
|
Abstract:
Based on the DB2 method,an adaptive method called IncreDB2 is proposed to detect and adapt to local concept drift continuously in data stream classification.This method dynamically maintains a hierarchical classification tree.When local concept drift is detected,IncreDB2 only updates the nodes that affected by this drift rather than rebuilds a new classification tree from scratch,which means that it has better time efficiency.Experimental results demonstrated the validity and efficiency of this method.
