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, PCA/ICA, HMMs and emsemble models.

Important: All our online/help sessions will be provided through Microsoft Teams available for free to all UoB students [use your Bristol email]. Please make sure to download the app here and join using the Join Teams link on your left (BB unit page menu).

Assessment Details

The assessment for this unit can be one of the following options:

  1. 100% Coursework assessment [W9-W11]. Deadline: TBA. The CW will be available here.
  2. 100% Exam assessment [Multiple Choice]

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.

Installation Instructions:

Jupyter Notebook - For all COMS30035 needs you are encouraged to install Anaconda (Python 3.7) as it bundles all the course's requirements. Alternatively for manual installation, you will require Python 3.7.x with 'Jupyter' and 'iPython' both possibly in version 4.x.x. All the packages needed will be listed at the beginning of each lab sheet.

If you login remotely to the university Linux machines, you should be able to just run Jupyter Notebook with this command
$ /opt/anaconda3-4.4.0/bin/jupyter notebook

For help on logging in remotely to Bristol machines see here.


Programming in a Browser
If you feel as akward as me about the idea about coding in a webbrowser you can use Emacs to render Jupyter notebooks. This way you get the finest of editing while at the same time having the benefit of Jupyter. Have a look at this repository on how to make it work URL. Here is a video showing how it can be done URL.

Text books

  1. 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.
  2. Murphy, K., Machine learning a probabilistic perspective (2012). We will also use this book for parts of the topics covered. This is a more recent textbook and provides a particularly good coverage of probabilistic methods. The book is freely available here.

Github

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