Generalized reparametrized variational Bayes with skew-symmetric normalization
Aoxiang Chen, Linda S. L. Tan
Bayesian hierarchical models with high-dimensional latent structure require scalable posterior approximations that preserve key dependencies while remaining computationally tractab…

Variational inference based on a subclass of closed skew normals
Linda S. L. Tan, Aoxiang Chen
Gaussian distributions are widely used in Bayesian variational inference to approximate intractable posterior densities, but the ability to accommodate skewness can improve approxi…
