ACM40990 Optimisation in ML

Academic Year 2023/2024

This module introduces students to the mathematical techniques that form the cornerstone of Machine Learning. Students will first of all study in depth the key concepts in continuous optimization (unconstrained, constrained, and global), before going on to apply these concepts to common algorithms in Machine Learning.

Learning Outcomes:

On completion of this module, students should be able to:

1. Formulate standard optimization techniques in continuous optimization, understand the convergence criteria, and implement these methods from scratch;
2. Implement the same methods using standard software packages, understand when these methods will work well and when they won’t;
3. Understand the first-order necessary conditions for optimality in constrained optimization, be able to solve simple problems by hand
4. Understand the need for global optimization, implement a simulated-annealing algorithm
5. Using Python programming, apply optimization techniques to problems in Machine Learning

Indicative Module Content:

Topics covered: Steepest-Descent and Newton-type methods, including analysis of convergence, Trust-region methods, including the construction of solutions of the constrained sub-problem. Numerical implementations of standard optimization methods. Necessary first-order optimality conditions. Introduction to Global Optimization, to include a discussion on Simulated Annealing. Application of optimization techniques through worked examples in Python. Examples may include: Linear Regression, Matrix Completion and Compressed Sensing, Support Vector Machines, and Neural Networks.
