Multivariate Time Series Data Imputation via Distributionally Robust Regularization
Multivariate time series imputation is often compromised by mismatch between the observed and true data distributions, a bias induced by the combined effects of time-series non-stationarity and systematic missingness. St…
Multivariate Time Series ImputationFADTI: Fourier and Attention Driven Diffusion for Multivariate Time Series Imputation
Multivariate time series imputation is fundamental in applications such as healthcare, traffic forecasting, and biological modeling, where sensor failures and irregular sampling lead to pervasive missing values. However,…
