While fat-tailed densities commonly arise as posterior and marginal distributions in robust models and scale mixtures, they present a problematic scenario when Gaussian-based variational inference fails to accurately capture tail decay. We first improve previous theory on tails of Lipschitz flows by…
In order to construct accurate proposers for Metropolis-Hastings Markov Chain Monte Carlo, we integrate ideas from probabilistic graphical models and neural networks in an open-source framework we call Lightweight Inference Compilation (LIC). LIC implements amortized inference within an open-univers…
We establish a fundamental connection between Bayesian experimental design and determinantal point processes (DPPs). Experimental design is a classical task in combinatorial optimization, where we wish to select a small subset of $d$-dimensional vectors to minimize a statistical optimality criterion…
