general "how do I do this?" question.
Say, I have a Rails app where users can browse books. I want there to be a recommendations page that lists books recommended for that specific user based on an algorithm that integrates data from Facebook's Open Graph. A simplified version of this algorithm would look something like:
a(Number of your facebook friends that have liked this book) + b(total number of people that like this book)
Where a and b are weighting coefficients.
Where in rails would I calculate this formula to return the recommendations? Is there a gem that helps with creating dynamic rankings?
Any help would be great!
Welcome to a rabbit hole. Enjoy the fall!
You're generally talking about Support Vector Machines. Here's some decent starting points:
