À propos de ce cours : In this course, you will learn the fundamental techniques for making personalized recommendations through nearest-neighbor techniques. First you will learn user-user collaborative filtering, an algorithm that identifies other people with similar tastes to a target user and combines their ratings to make recommendations for that user. You will explore and implement variations of the user-user algorithm, and will explore the benefits and drawbacks of the general approach. Then you will learn the widely-practiced item-item collaborative filtering algorithm, which identifies global product associations from user ratings, but uses these product associations to provide personalized recommendations based on a user's own product ratings.

It would be better to provide other programming language such as python in honour assignment. And in the assignment should more emphasis on the algorithm not rely on too much others such as Lenskit.
(+) The course material is good with real world examples and interviews with different people.
(+) Interesting material
(-) The assignments had mistakes.
(-) There is no example provided for practice before jumping into assignments.
very nice
Diverse content that helps in understanding the basic concepts of collaborative filtering. Interviews with people specializing in different nuances of collaborative filteering were very useful.
Some thoughts on what could be improved
Pace of narration. It can be faster
More exercises are needed to get more familiar with the concepts. Each lecture should have a exercise (not just a quiz)
