Vector Copula Variational Inference and Dependent Block Posterior Approximations
Yu Fu, Michael Stanley Smith, Anastasios Panagiotelis
The key to VI is the selection of a tractable density to approximate the Bayesian posterior. For large and complex models a common choice is to assume independence between multivar…

On approximating the -divergence between two Ising models
Weiming Feng, Yucheng Fu
The -divergence is a fundamental notion that measures the difference between two distributions. In this paper, we study the problem of approximating the -divergence between t…
