Department of Engineering  
Taught By: Zoubin Ghahramani and Carl Edward Rasmussen
Code and Term: 4F13 Lent term
Year: 4th year (part IIB) Engineering, also open to MPhil and PhD students.
Structure & Assessment:14 lectures, 2 example papers, 2 assigments (25%) and final exam (75%).
Time: 11am to 12noon Wednesdays, and 10am to 11am Fridays
Location: Lecture Room 5, First floor, Engineering Building, Trumpington Street, Cambridge
Prerequisites: A good background in statistics, calculus, linear algebra, and computer science. 3F3 Signal and Pattern Processing and 4f10 Statistical Pattern Processing would both be useful. You should thoroughly review the maths in the following cribsheet [pdf] [ps] before the start of the course. The following Matrix Cookbook is also a useful resource. If you want to do the optional coursework you need to know Matlab or Octave, or be willing to learn it on your own. Any student or researcher at Cambridge meeting these requirements is welcome to attend the lectures. Students wishing to take it for credit should consult with the course lecturers.
Textbook: There is no required textbook. However, the material covered is treated in:
Christopher M. Bishop (2006) Pattern Recognition and Machine Learning. Springerand we will provide references to sections in this book. Another excellent textbook is:
David J.C. MacKay (2003) Information Theory, Inference, and Learning Algorithms, Cambridge University Press, available freely on the web.For a summary of the topics covered in this module you can read the following chapter:
Ghahramani (2004) Unsupervised Learning. In Bousquet, O., Rätsch, G. and von Luxburg, U. (eds)NOTE: If you want to see lecture slides from a similar but not identical course ZG taught last year click on the 2006 course website, but be warned that the slides will change this year.
