Content
The course provides you with a thorough understanding of statistical/probabilistic machine learning methods that are used in a wide range of different fields with a focus on unsupervised learning. The course covers four main topics:
- probabilistic graphical models,
- exact inference,
- learning,
- approximate inference and learning.
The course material is available here and optional material here.
Assessment
Overview
- The course is assessed by a written exam at the end of the course (75% of final mark) and three quizzes during the semester (25% of final mark). There is no assignment.
- The quizzes check your engagement with the course and are typically easier than the exam.
- The exam date is announced here and past exams are available here (search for probabilistic modelling and reasoning).
- PMR follows the Common Marking Scheme of the university and the school-wide academic conduct policy.
Quizzes
- The quizzes open 1 week prior to their due date. They are time-limited and you will you have 1 attempt for each quiz.
- The maximal time to complete a quiz is 60 minutes. The 60 mins will allow you to consult the slides or tutorials, but you will still need to study the material beforehand. Otherwise, you will likely run out of time.
- The quizzes are available on gradescope. Please access it via Learn.
- The quizzes will be autosaved and you can revise them as often as you want but once you have started a quiz, you will have to finish it within 60 minutes after you started.
- When a quiz “closes at 4pm”, it means that you can work on it until 4pm.
Test quiz: Opens Feb 06 at 3pm, closes Friday Feb 11 at 4pm
Thursday Feb 17 at 6pm. This is to check that you can access gradescope
and allows you to familiarise yourself with the types of questions
asked in the quizzes. It takes less than five minutes to
complete. Please get in
touch with Michael in case of access problems or questions.
Quiz 1: Opens Friday Feb 11 at 3pm, closes Friday Feb 18 at 4pm (end of week 5). The quiz is on directed and undirected graphical models. It covers the material on the slides until (and including) “Undirected Graphical Models II”, and the exercises discussed in tutorials 1 and 2.
Quiz 2: Opens Friday March 4 at 3pm, closes Friday March 11 at 4pm (end of week 7). The quiz is on inference and message passing. It covers the material on the slides “Factor Graphs” and “Exact Inference”, and the exercises discussed in tutorial 4.
Quiz 3 Opens Friday March 18 at 3pm, closes Monday March 28 at
4pm (beginning of week 10) Wednesday March 30 at 4pm. The quiz is on learning. It covers the
slides Basics of Model-Based Learning, Factor Analysis and
Independent Component Analysis, Intractable Likelihood Functions,
and Estimating Unnormalised Models by Score Matching, as well as
Tutorial 6, Exercises 1-9.
Note: you will have to do some calculations by hand. So please have pen and paper ready.
