Bayesian inversion, uncertainty analysis and interrogation using boosting variational inference
Geoscientists use observed data to estimate properties of the Earth's interior. This often
requires non‐linear inverse problems to be solved and uncertainties to be estimated …

EigenVI: score-based variational inference with orthogonal function expansions
We develop EigenVI, an eigenvalue-based approach for black-box variational inference
(BBVI). EigenVI constructs its variational approximations from orthogonal function …

Variational prior replacement in Bayesian inference and inversion
Many scientific investigations require that the values of a set of model parameters are
estimated using recorded data. In Bayesian inference, information from both observed data …

Batch and match: black-box variational inference with a score-based divergence
Most leading implementations of black-box variational inference (BBVI) are based on
optimizing a stochastic evidence lower bound (ELBO). But such approaches to BBVI often …

Bayesian coresets: Revisiting the nonconvex optimization perspective
Bayesian coresets have emerged as a promising approach for implementing scalable
Bayesian inference. The Bayesian coreset problem involves selecting a (weighted) subset of …

Universal boosting variational inference
Boosting variational inference (BVI) approximates an intractable probability density by
iteratively building up a mixture of simple component distributions one at a time, using …

MixFlows: principled variational inference via mixed flows
This work presents mixed variational flows (MixFlows), a new variational family that consists
of a mixture of repeated applications of a map to an initial reference distribution. First, we …

Variational Bayesian decision-making for continuous utilities
Bayesian decision theory outlines a rigorous framework for making optimal decisions based
on maximizing expected utility over a model posterior. However, practitioners often do not …

Competitive training of mixtures of independent deep generative models
A common assumption in causal modeling posits that the data is generated by a set of
independent mechanisms, and algorithms should aim to recover this structure. Standard …
