Bayesian Distance-to-Set Models: from Latent Variable to Latent Projection

Statistical models often assume that data are generated near a structured, smooth, or low-dimensional set. A common approach is to use …

Generative Bayesian Inference with GANs

In the absence of explicit or tractable likelihoods, Bayesians often resort to approximate Bayesian computation (ABC) for inference. …

Likelihood-free Inference via Structured Score Matching

In many statistical problems, the data distribution is specified through a generative process for which the likelihood function is …

Haoyu Jiang, Yuexi Wang, Yun Yang

Simulation-based Inference via Langevin Dynamics with Score Matching

Simulation-based inference (SBI) enables Bayesian analysis when the likelihood is intractable but model simulations are available. …

An Optimal Transport-Based Generative Model for Bayesian Posterior Sampling

We investigate the problem of sampling from posterior distributions with intractable normalizing constants in Bayesian inference. Our …

Pochhammer Priors for Sparse Count Models

Bayesian inference for Dirichlet-Multinomial (DM) models has a long and important history. The concentration parameter $\alpha$ is …

Data Augmentation for Bayesian Deep Learning

Deep Learning (DL) methods have emerged as one of the most powerful tools for functional approximation and prediction. While the …

Approximate Bayesian Computation via Classification

Approximate Bayesian Computation (ABC) enables statistical inference in simulator-based models whose likelihoods are difficult to …

Variable Selection with ABC Bayesian Forests

Few problems in statistics are as perplexing as variable selection in the presence of very many redundant covariates. The variable …
