Anomaly pattern detection for streaming data
作者:
Highlights:
• We propose an anomaly pattern detection method for streaming data.
• It detects a point where the pattern is unusually different from normal behavior.
• A data stream is transformed into a stream of binary values indicating outliers.
• An anomaly pattern on a stream of binary values is detected by two approaches.
• The proposed method is not sensitive to the performance of outlier detection method.
