Representations of loop groups as factorization module categories
Lin Chen, Yuchen Fu, Dennis Gaitsgory +1
We show that the (2-)category of categorical representations of the loop group embeds fully faithfully into the (2-)category of factorization module categories with respect to the…

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…

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…
