From Coursera - we use ML in a few places:
1. Course Recommendations. We use low rank matrix factorization approaches to do recommendations, and are also looking into integrating other information sources (such as your career goals).
2. Search. Results are relevance ranked based on a variety of signals from popularity to learner preferences.
3. Learning. There's a lot of untapped potential here. We have done some research into peer grading de-biasing [1] and worked with folks at Stanford on studying how people learn to code [2].
We recently co-organized a NIPS workshop on ML for Education: http://ml4ed.cc http://ml4ed.cc . There's untapped potential in using ML to improve education.

- zardeh 10y agoI'm curious, because this is something that I was interested in doing for brick and mortar universities, what aspects do you use to do your recommendations. That is, is it just a x/5 rating per user that is thrown into a latent factor model, or do you do anything else (like dividing course 'grade' vs. opinion along two axes manually?)
- rsrsrs86 10y agoAre you just weighing different scores on 2? That would be heuristics more precisely. Not really learning; Unless you update the weights my minimizing some cost function.
