DAMR: Dynamic Adjacency Matrix Representation Learning for Multivariate Time Series Imputation
Summary: Dynamic adjacency matrices capture evolving spatial correlations in multivariate time series, decomposing into constant, long-term trends and periodic patterns. DAMR aggregates these dynamic graphs and applies a graph representation learning layer for missing-value imputation, yielding up to 19.4% MAE improvement over SOTA.
