In this course you will learn how to evaluate recommender systems. You will gain familiarity with several families of metrics, including ones to measure prediction accuracy, rank accuracy, decision-support, and other factors such as diversity, product coverage, and serendipity. You will learn how different metrics relate to different user goals and business goals. You will also learn how to rigorously conduct offline evaluations (i.e., how to prepare and sample data, and how to aggregate results). And you will learn about online (experimental) evaluation. At the completion of this course you will have the tools you need to compare different recommender system alternatives for a wide variety of uses.

Reviews summary
Practical offline evaluation
Learners say this course provides practical offline evaluation in Recommender Systems, but more practice with online evaluation would make this course more valuable.
Offline evaluations are practical.
"the part of offline evaluation is really good and practical as well."
The course lacks practice with online evaluation.
"However, although knowing online evaluation is a more complex subject, I felt it lacked a little bit how to put all this knowledge in practice."
