Abstract  Most of the existing concept drift detection methods focus on single label data stream, and therefore they cannot meet the requirements of multi-label data stream concept drift detection. A concept drift detection algorithm of multi-label data stream based on hierarchical verification is proposed. The proposed algorithm consists of a test layer and a verification layer. The variation of data distribution is detected by the test layer to judge whether the concept drift occurs or not. The variation degree of tag confusion matrix is judged by the verification layer to verify whether the concept drift occurs indeed or not. Experiments on real multi-label and synthetic multi-label datasets indicate that the proposed algorithm detects the concept drift effectively and improves the classification performance.
