Time Series Data Cleaning: From Anomaly Detection to Anomaly Repairing

Summary: Proposes iterative minimum repairing (IMR) for time series, repairing anomalies via temporal context and the minimum-change principle. Convergence analysis and incremental O(1) per-iteration parameter estimation reduce cost from O(n) to O(1); real-data experiments show superior repair and improved time-series classification.
