Streaming Anomaly Detection Using Randomized Matrix Sketching
Summary: Unsupervised, one-pass streaming anomaly detection via randomized matrix sketching; maintains an orthogonal basis for observed data. Anomalies detected by reconstruction error; competitive with offline SVD, with speedups from randomized low-rank approximations. (summarized by gpt-5-nano on Feb 09 2026)
