Spatiotemporal Imputation with Graph-Informed Flow Matching
Researchers have introduced GiFlow, a novel framework designed for spatiotemporal imputation, which addresses the challenge of missing data in time-series applications. Unlike traditional methods that can accumulate errors, GiFlow utilizes a graph-informed prior and a hybrid vector field model to jointly capture spatial and temporal dependencies. This approach has demonstrated superior performance over existing state-of-the-art techniques in experiments on both synthetic and real-world datasets. AI
