Two new papers on arXiv explore Bayesian hierarchical models in machine learning. The first paper by Brendon Brewer demonstrates how a maximum entropy property emerges in dependent marginal priors when the prior given hyperparameters is canonical. The second paper by Alexander Dombowsky introduces a hierarchical model for discrete Bayesian networks that induces shrinkage to low-dimensional latent parameters, with an application to breast cancer data.
