Streaming Time Series Subsequence Anomaly Detection: A Glance and Focus Approach

Summary: Sirloin: streaming subsequence anomaly detection with a novel "glance-and-focus" score that jointly models global and local patterns to boost detection accuracy. Dynamically maintains inverted-file indexes and product-quantization codebooks with dual-index optimization to adapt to evolving series and speed processing (≈4× throughput, +58% accuracy vs streaming SOTA).
