All course material has now been marked, and will be available for pickup in my office 3-4pm on May 7 and 3-4pm on May 9.

Note that marks for test 1 and test 3 were taken as out of 80, even though the maximum possible was 100.

**Instructor:**

Radford Neal,Office:SS6026A,Phone:(416) 978-4970,Email:radford@stat.utoronto.caOffice Hours: Tuesdays 3:10-4:00pm, in SS6026A.

**Lectures:**

Tuesdays 12:10-2:00pm and Thursdays 12:10-1:00pm, in SS 2127.

The first lecture is January 7. The last lecture is April 3.

There are no lectures February 17 to 21 (Reading Week).Graduate students in STA 2104 will make presentations the week of April 7 to 11.

**Evaluation:**

For undergraduates in STA 414:52% Three assignments.For graduate students in STA 2104:

48% Three 50-minutes tests, each worth 16%, held in lecture time on February 6, March 13, and April 3.48% Three assignments.

42% Three 50-minutes tests, each worth 14%, held in lecture time on February 6, March 13, and April 3.

10% A 12-minute individual presentation on a conference paper that you have read.The assignments are to be done by each student individually. Any discussion of the assignments with other students should be about general issues only, and should

notinvolve giving or receiving written, typed, or emailed notes.Graduate students may discuss the conference paper that they will present with anyone, in order to help understand it, but they must prepare their presentation themselves. (They may if they wish solicit feedback from others after a practice run of their presentation.)

**Textbook:**

The book

Machine Learning: A Probabilistic Perspective, by Kevin P. Murphy, is strongly recommended (but not required).I will be posting lecture slides, and links to online references.

**Computing:**

Assignments will be done in R. Statistics Graduate students will use the Statistics research computing system. Undergraduates and graduate students from other departments will use CQUEST. You can request an account on CQUEST if you're an undergraduate student in this course (you need to fill out a form if you're a grad student).You can also use R on your home computer by downloading it for free from www.R-project.org. From that site, here is the Introduction to R.

You might also be interested in trying out my faster implementation of R, called pqR, available from pqR-project.org (However, it currently is distributed only in source form, and is easily installed only on Linux/Unix systems.)
