Time Series Data Validity
Summary: First study to define time-series validity via a minimum-change repair objective that maximizes preserved data. Quadratic-time, linear-space algorithms adapt to LSM-based storage; exposed as a SQL function in Apache IoTDB, with up to 10^4× faster than SCREEN on 8 datasets.
