Thank you for the introductory work! Good summary and well explained! What if you want to develop a recommendation algorithm on your own? Any suggestions?

• Bigdata Doc says:

Well, the R package I mentioned in this post is properly speaking a framework to test your recommendation approaches with the most famous algorithms already implemented. Have a look at the package documentation! Otherwise, try to implement it yourself from scratch! It’s big fun 🙂
