Likelihood Based Inference in Fully and Partially Observed Exponential Family Graphical Models with Intractable Normalizing Constants

1 code implementation27 Apr 2024 Yujie Chen, Anindya Bhadra, Antik Chakraborty

Probabilistic graphical models that encode an underlying Markov random field are fundamental building blocks of generative modeling to learn latent representations in modern multivariate data sets with complex dependency structures.

Fast sampling with Gaussian scale-mixture priors in high-dimensional regression

2 code implementations15 Jun 2015 Anirban Bhattacharya, Antik Chakraborty, Bani K. Mallick

We propose an efficient way to sample from a class of structured multivariate Gaussian distributions which routinely arise as conditional posteriors of model parameters that are assigned a conditionally Gaussian prior.
