Short Course: Bayesian Statistical Learning

Course outline

The Bayesian approach to statistical inference has gained widespread use in Statistics and Machine Learning. This course aims to provide a solid introduction to Bayesian data analysis via a mixture of theoretical and methodological concepts, with an emphasis in computer implementation of modern simulation algorithms. The course will be presented through four modules (see details below). The first module introduces the Bayesian paradigm and develops inferential tools for some simple models. The second module considers more advanced models, such as linear regression, spline regression and classification models. The third module focuses on computation and presents state-of-the-art algorithms to carry out Bayesian inference. Finally, the fourth module presents model comparison techniques and advanced topics such as Bayesian variable selection and hierarchical models. In each module, the students will be presented the underlying theory and methodology, which will then be demonstrated through an assignment the students will carry on individually. The computer lab session will then discuss possible solutions. Students will gain knowledge in modern state-of-the-art Bayesian methods that can be applied to solve complex problems in Statistics and Machine Learning. The course puts a lot of emphasis on computer implementation of the presented material. The recommended programming language to solve the computer labs is R because the material presented will use it. However, students may use any software they want (e.g. Python or Julia).

Schedule

The course consists total 32 hours, including 12 lectures of 2 hours each (24 hours lecture time in total) and 4 computer labs of 2 hours each (8 hours computer lab time in total). The proposed weekly schedule is 3 lectures followed by 1 computer lab. The course can then be taught over 4 weeks. The course is divided into 4 modules, so 1 module can be taught over 1 week. The lecturer will deliver the lectures and the computer labs will be interactive sessions.

Lecturer

Dr Matias Quirozis a Senior Lecturer at the School of Mathematical and Physical Sciences at the University of Technology Sydney.He is also an Associate Investigator in ARC Centre of Excellence for Mathematical and Statistical Frontiers (ACEMS).DrQuiroz’sresearch interests lie in the area of Bayesian Statistics. In particular,he is interested in Bayesian computations, such as Monte Carlo methods and variational Bayes. His research output appeared in top tier journals such asJournal of the American Statistical Association,Journal of Computational and Graphical Statistics,Journal of Machine Learning Research,Proceedings of International Conference on Machine Learning (ICML).

Prerequisites

This course is suitable for students who have taken at least one course in statistics above the introductory level and have some programming experience. The students should be confident in their knowledge of concepts such as integrals, derivatives, probability distributions, conditional probability and expectations. The students should have some basic knowledge in linear algebra, including matrix operations such as multiplication and inverses, and concepts such as eigenvalues and eigenvectors. A good and compact text of the mathematical tools used in this subject can be found here:https://gwthomas.github.io/docs/math4ml.pdf. However, note that we will only encounter a subset of these, so students are not expected to know the whole content.
