When Imputation Changes the Nearest Neighbor: Exact Certification of Similarity Retrieval for Incomplete Sensor Time Series

Oct 29, 2026 Source ↗

Key Insights

Sensor time series routinely reach similarity search with missing values, and the retrieved neighbours then depend on how the gaps were filled.
We ask which retrieval conclusions hold for every admiss.
