INS Workshop on Bayesian Data Analysis

With Michael Betancourt, taking place between May 17th to 19th, 2022

Salle informatique 204 - b timent p dagogique (Facult  de M decine,

27, Boulevard Jean Moulin - 13005 Marseille, France)

Due to the importance and common use of Bayesian framework for inference and prediction, the

advanced techniques in probabilistic programming languages to overcome the inference

difficulties with big data complemented with big models have been receiving increasing attention

in this context. Stan is a popular platform for facilitating inference, providing an expressive

modeling language and implementing state-of-the-art algorithms to draw subsequent Bayesian

inferences.

We are very happy to announce the INS courses on "Bayesian Data Analysis", with Michael

Betancourt, a core developer of Stan and expert in Hamilton Monte Carlo. The courses begin by

surveying Bayesian inference, Bayesian computation and a principled introduction to Stan.

With a solid foundation, we will move onto to the elements of a robust Bayesian workflow in

practice and then continue to the problem of interest to neuroscienist such as source localization

in Neuroimaging.

The courses are highly interactive, with exercises demonstrating a principled Bayesian workflow

and range of modeling techniques run in Python environment. Courses run for 3 days and

include material spanning Probabilistic modelling, identifiability and degeneracy, Bayesian

workflows and Hierarchical modelling.

Prerequisites for the course

The course will assume familiarity with the basics of calculus, linear algebra, and probability

theory. For a self-contained introduction to the latter please review my probability theory,

conditional probability theory, and common probability densities case studies. The last will be

particularly relevant.
