Unit Information

This unit seeks to acquaint students with machine learning algorithms which are important in many modern data and computer science applications. We cover topics such as kernel machines, probabilistic inference, neural networks, HMMs and emsemble models.

Lecturer

Assessment Details

If you are doing this unit as a MAJOR (assessment unit COMS30083) then you do a mid-term in-class test during w/c 26 Oct (worth 30% of the unit) and also coursework (worth 70% of the unit). Coursework tasks are released by 1500 on Friday 13 Nov 2026 and students' coursework is to be submitted by Thursday 3 Dec 2026.
If you are doing this unit as a MINOR (assessment unit COMS30081) then you are assessed by the ML questions in the "Topics in Computer Science" closed-book exam in December (worth 100% of the unit).

Lab Work

The labs are formative assessements which we strongly encourage you to complete. Note that these were designed to help your understanding of ML methods.

Using the machines in MVB 2.11

If you are using UoB machines to do the lab exercises (as opposed to using your own machine) you need to do the following.

Make sure the machine you are using is running Linux (reboot if necessary).
Open up a Terminal window so you have access to the Linux command line.
Enter the following at the command line: module load anaconda/3-2025

Using your own machine

If you want to do lab exercises on your own machine then you should install Anaconda on it. If you run into installation problems then feel free to ask the Teaching Staff on the unit for help, but we can't guarantee to solve them.

Text books

Bishop, C. M., Pattern recognition and machine learning (2006). This is one of the best ML textbooks and will be our main textbook. The book is freely available here.
Murphy, K., Probabilistic Machine Learning: An Introduction (2022) and Murphy, K., Probabilistic Machine Learning: Advanced Topics (2023). We will also use this book series for some topics. These are more recent textbooks and provide a particularly good coverage of probabilistic methods. The books are freely available via here.

All technical resources (including the labs) will be posted on the COMS30035 Github organisation. If you find any issues, please kindly raise an issue in the respective repository.
