The Reverse Telescoping Coordinate System for Positive Definite Matrices: Geometry, Computation, and Generative Modeling
Anindya Bhadra
We design a new unconstrained coordinate system where a symmetric positive definite (SPD) matrix is represented by a reverse telescoping map , wi…

Exact and Approximate MCMC for Doubly-intractable Probabilistic Graphical Models Leveraging the Underlying Independence Model
Yujie Chen, Antik Chakraborty, Anindya Bhadra
Bayesian inference for doubly-intractable pairwise exponential graphical models typically involves variations of the exchange algorithm or approximate Markov chain Monte Carlo (MCM…

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