Annealing in variational inference mitigates mode collapse: A theoretical study on Gaussian mixtures
Annealing in variational inference mitigates mode collapse: A theoretical study on Gaussian mixtures arXiv:2602.12923v1 Announce Type: new Abstract: Mode collapse, the failure to capture one or more modes when targetting a multimodal distribution, is a central challenge in modern variational inference. In this work, we provide a mathematical analysis of annealing based strategies for mitigating…

Sparse-mode Dynamic Mode Decomposition for Disambiguating Local and Global Structures
Sparse-mode Dynamic Mode Decomposition for Disambiguating Local and Global Structures arXiv:2507.19787v1 Announce Type: new Abstract: The dynamic mode decomposition (DMD) is a data-driven approach that extracts the dominant features from spatiotemporal data. In this work, we introduce sparse-mode DMD, a new variant of the optimized DMD framework that specifically leverages sparsity-promoting regularization in order to…

Diffusion-based supervised learning of generative models for efficient sampling of multimodal distributions
Diffusion-based supervised learning of generative models for efficient sampling of multimodal distributions arXiv:2505.07825v1 Announce Type: new Abstract: We propose a hybrid generative model for efficient sampling of high-dimensional, multimodal probability distributions for Bayesian inference. Traditional Monte Carlo methods, such as the Metropolis-Hastings and Langevin Monte Carlo sampling methods, are effective for sampling from single-mode distributions…
