Variational Bayesian modelling of mixed-effects

no code implementations21 Mar 2019 Jean Daunizeau

This note is concerned with an accurate and computationally efficient variational bayesian treatment of mixed-effects modelling.

On parameters transformations for emulating sparse priors using variational-Laplace inference

no code implementations6 Mar 2017 Jean Daunizeau

So-called sparse estimators arise in the context of model fitting, when one a priori assumes that only a few (unknown) model parameters deviate from zero.

The variational Laplace approach to approximate Bayesian inference

no code implementations2 Mar 2017 Jean Daunizeau

Variational approaches to approximate Bayesian inference provide very efficient means of performing parameter estimation and model selection.
