Boosting Variational Inference

no code implementations17 Nov 2016 Fangjian Guo, Xiangyu Wang, Kai Fan, Tamara Broderick, David B. Dunson

Variational inference (VI) provides fast approximations of a Bayesian posterior in part because it formulates posterior approximation as an optimization problem: to find the closest distribution to the exact posterior over some family of distributions.

Variational Inference

Parallelizing MCMC with Random Partition Trees

2 code implementations NeurIPS 2015 Xiangyu Wang, Fangjian Guo, Katherine A. Heller, David B. Dunson

The new algorithm applies random partition trees to combine the subset posterior draws, which is distribution-free, easy to resample from and can adapt to multiple scales.
