Description

Title:
“Bayesian Learning: Fundamentals and Beyond”

By

Sergios Theodoridis, Professor of Signal Processing and Machine Learning in the Department of Informatics and Telecommunications University of Athens.

 

Abstract
In this lecture, the basic concepts of Bayesian Learning will be introduced. The notions of ML and MAP will be first reviewed and the concepts of prior and posterior information will be introduced. The importance of the evidence function in the context of Occam's razor rule will be discussed and then we will move on latent variables and the EM algorithm. Its lower bound interpretation will be presented. Two case studies, namely regression and mixture modelling will be discussed.

 

Building upon the lower bound interpretation of the EM, the variational approximation in Bayesian learning will be introduced and some basic related concepts will be reviewed. Two notable applications, namely regression and probability mixture modelling will be discussed.

If there is time left, a discussion on nonparametric modelling in the context of Gaussian processes will be briefly discussed.
