On the reliable detection of concept drift from streaming unlabeled data

作者:

Highlights:

• New classifier-independent, dynamic, unsupervised approach for detecting concept drift.

• Reduced number of false alarms and increased relevance of drift detection.

• Results comparable to supervised approaches, which require fully labeled streams.

• Our approach generalizes the notion of margin density, as a signal to detect drifts.

• Experiments on cybersecurity datasets, show efficacy for detecting adversarial drifts.
