Ask HN: Has anyone built a recommendation engine in-house?

I've built a recommender system for my movie database app "Coollector Movie Database". It's based on Collaborative filtering and it took me 2 years to implement. I built it from scratch and it's unique in several ways (for example, you can view the reliability of each recommendation). The technical difficulty is to crunch fast enough a huge quantity of data. I've had to apply all the optimizations that I could think…

How would you generalize the method you are using?

I don't like ML frameworks (Tensorflow, etc...), maybe it's because I haven't tried them. My understanding is that they're like a magic black box: you input some data, you adjust some settings, and you wish for the results to be good. Instead, I've taken a direct approach to the collaborative filtering problem, the difficulty being to correlate a huge amount of data. Some said that only quantum computers would one day be fast enough to solve the recommendation problem, until recently a student demonstrated that it could be solved with classical computers.

This student's algorithm is quite different from mine, but I suppose that my algorithm is yet another example of solving the recommendation problem with classical computers.
