High-Dimensional Differential Parameter Inference in Exponential Family using Time Score Matching

Published in The 28th International Conference on Artificial Intelligence and Statistics (AISTATS 2025), 2025

This paper addresses differential inference in time-varying parametric probabilistic models and proposes to directly learn the time derivative of parameters via time score matching.

Missing Data Imputation by Reducing Mutual Information with Rectified Flows

Published in arXiv preprint, 2025

This paper introduces a novel iterative method for missing data imputation that sequentially reduces the mutual information between data and their corresponding missing mask.
