SAND: Streaming Subsequence Anomaly Detection

Summary: SAND: streaming, online, domain-agnostic subsequence anomaly detection. It updates a normal-behavior model online to track drift, without needing full data, and detects both isolated and recurring anomalies, with large speedups over state-of-the-art.
