Guiding Time-Varying Generative Models with Natural Gradients on Exponential Family Manifold

UAI 2025

Optimising probabilistic models is a well-studied field in statistics. However, its connection with the training of generative models remains largely under-explored. In this paper, we show that the evolution of time-varying generative models can be projected onto an exponential family manifold, natu

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

AISTATS 2025poster

This paper addresses differential inference in time-varying parametric probabilistic models, like graphical models with changing structures. Instead of estimating a high-dimensional model at each time and estimating changes later, we directly learn the differential parameter, i.e., the time derivati…

Missing Data Imputation by Reducing Mutual Information with Rectified Flows

NeurIPS 2025poster

This paper introduces a novel iterative method for missing data imputation that sequentially reduces the mutual information between data and the corresponding missingness mask. Inspired by GAN-based approaches that train generators to decrease the predictability of missingness patterns, our method e…
