Nearest Neighbor Collaborative Filtering

All in all, it is a comprehensive introduction to collaborative filtering.

Provides a good overview of item based and user based collaborative filtering approaches.

Thank you for this course -- it opened my eyes to the universal applicability of recommender systems in tech applications.

Excellent course providing not only the knowledge of algorithms but also useful insights into developing and maintaining recommender systems.

Spreadsheet assignment in week 4 is poorly designed (as evidenced by many forum threads with people not knowing what is it that the authors actually want).

Spreadsheet assignment on Week 3 is the main reason I rate this course so low, and a lot of people on discussion forums agree with me on assignment quality Week 4 assignments can do with a bit more clarity.

Loved it...many thanks Prof. Joe for bringing this content to Coursera a great class, I learned some insight in these algorithms Very good course, there is a glaring error in Week 4s assignment.

But if you check the forums it can be easily solved Very satisfied to do this, the videos are too long, very good quality and a lot of practical information.I love it!

Forum is also a little bit deserted, although contains some critical hints to pass the assignments (such a hints worth to be included in the assignment descriptions itself).

Rather non-technical, interesting general information, plus voluntary programming assignment which I personally found little bit "bulky".

However the exercise needs a bit more work to be very useful.

I think this is very useful for introductory, but it lacks some references for who wants go deeper.

I also wish the lectures cover actual mathematical examples to work us through the algorithms Thank you so very much to open my eye see more view of recommendation field not only algorithms but use case and many trouble-shooting in worldwide business, moreover interview with noble professor.

good introduction to topics and algorithms but very little help provided for the assignment in clarifying doubts in forums and unclear explanations were given for assignments.
