Overview
This is an advanced course on machine learning, focusing on recent advances in machine learning with relational data and on Bayesian approaches to machine learning. The course is organized and taught as follows:
- Relational learning (Ismail Ilkan Ceylan): 9 lectures
- Bayesian machine learning (Jiarui Gan): 5 lectures + Bayesian deep learning (Yarin Gal): 4 lectures
Learning outcomes
After studying this course, students will:
- Have knowledge of the different paradigms for performing machine learning and appreciate when different approaches will be more or less appropriate.
- Understand the definition of a range of neural network models, including graph neural networks.
- Be able to derive and implement optimisation algorithms for these models.
- Understand the foundations of the Bayesian approach to machine learning.
- Be able to construct Bayesian models for data and apply computational techniques to draw inferences from them.
- Have an understanding of how to choose a model to describe a particular type of data.
- Know how to evaluate a learned model in practice.
- Understand the mathematics necessary for constructing novel machine learning solutions.
- Be able to design and implement various machine learning algorithms in a range of real-world applications.
Prerequisites
Required background knowledge includes probability theory, linear algebra, continuous mathematics, multivariate calculus, and a basic understanding of graph theory, and logic. Students are required to have taken a Machine Learning course. Good programming skills are needed, and lecture examples and practicals will be given mainly in Python and PyTorch.
