A new review paper published on arXiv synthesizes research on missing data imputation across various disciplines. It categorizes methods from classical statistics to modern deep learning techniques, including GANs, diffusion models, and large language models. The paper also explores the integration of imputation with downstream tasks like classification and anomaly detection, and identifies future research directions such as privacy-preserving imputation and generalizable models.
