Week 1 (Jan 11)

  • Monday lecture: Zoom; Meeting ID: 672 5868 3175. Password: 245514. Recording. Slides.
  • Group assignment survey. Due Wed Jan 13 at 12pm Vancouver time.
  • Assignment 1. Due Monday, Jan 18, 11:59pm (time zone of your choice). This is a qualifying assignment; based on your performance on the assignment, we will recommend whether you have the prerequisites for the course. (For the purposes of the course grade, everyone will get full credit, so please represent your knowledge accurately.) You should expect to consult reference materials (e.g. textbooks, Wikipedia, etc), but if you find you need to re-read whole textbook chapters, that is a sign that you are missing the prerequisite knowledge.

Course information

Textbook: We will use a combination of two textbooks from Kevin Murphy.

  1. "Probabilistic Machine Learning: An Introduction" (2021). Available free online. We will use this for the first half of the course.
  2. "Machine Learning: A Probabilistic Perspective" (2012). We will use this for the section on probabilistic graphical models, the last half of the course.
  • Reading assignments will be posted on this page, due before the interactive session on Thursday.

Lectures (subject to change):

  • Content lectures will be recorded and posted, to be viewed asynchronously, due before the interactive session on Thursday.
  • We will have one synchronous interactive session per week, Thursdays 10:30am-Noon Vancouver time.
  • Attendance is mandatory at the interactive session. If this is challenging for you, e.g. due to time zone differences, please indicate in the survey (coming soon).
  • Depending on feedback, synchronous lecture times are subject to change after the first few weeks. Please reserve the full scheduled class times.

Assignments. There will be one written assignment per week, due on Monday.

  • Assignments will be due in two parts. Your first submission is individual, worth 2/3 of the grade.
  • The second submission, due one week later, is a joint group submission, worth 1/3 of the grade. This gives you a chance to fix any mistakes as a group. (Group grade is the maximum of the individual and group submission.)

Groups. The class will be divided into groups of 4-5 people each. You may request one person to be in the same group as you; please submit your request in the survey (coming soon).

Canvas discussion. Please use the Canvas discussion forum liberally to post any questions or discussion.

Enrollment. Everyone who wants to will get in off the waitlist. Anyone not officially enrolled is welcome to view the lectures and assignments. If you would like to attend the interactive sessions, please respond to the survey (coming soon) and indicate that you would like to be assigned to a group with other auditors.

Grading criteria are broken down as follows: 75% written assignments (11 assignments, 6.8% each); 15% final coding assignment; 10% attendance. You get two free missed attendance days.

Unofficial prerequisites: No official prerequisites. However, the course assumes knowledge of machine learning (CMPT 726), probability and linear algebra (MATH 240). The Assignment 1 is a qualifying assignment to show whether you have the necessary background.

The course is open to advanced undergraduates with permission. How to enroll as an undergraduate: Please follow the following steps: (1) Come to the first lecture, where I will explain the expected background. (2) Email me stating that you have taken a course in probability/statistics and a course in machine learning (CMPT 726). If it is appropriate, I will respond with my approval. (3) Fill out the prerequisite waiver form and attach a screenshot of our email exchange.

Overleaf. A great web-based Latex editor.
