ORBITS: Online Recovery of Missing Values in Multiple Time Series Streams
Summary: ORBITS recovers missing blocks in multiple time series online via incremental centroid decomposition, yielding linear-time imputation. Correctness proof and real-world evaluation show ~30% more accuracy over state-of-the-art with much higher efficiency. (summarized by gpt-5-nano on Feb 09 2026)
