Great examples, but I really wonder. Doesn't this kind of peration take too long to run? I mean running this kind of algorithm would probably take 30ms, but considering you might have thousends of users trying to run the algorithm simultaneously, it might be a pain in the ass. Aren't there better ways to deal with it?

Can I use the matrix factorization technique for recommendation where the scenario is like I have 972 unique user and 3810 unique items and 24 unique country id. Like in a common movie recommendation ratings are there and we predict ratings and then show recommendation system. In my case I have country id instead of ratings. is it fundamentally incorrect or I can go ahead with this?

Well what about the Google search engine? What kind of recommender system do they use? How do they decide the precedence of the search results for an user? Do they use content based filtering based on the search keywords, or does they use a hybrid recommender system where they first collect sites from the internet based on the search terms and then use collaborative filtering based upon all the users who have searched using the specific terms and then predict which link the user is most likely to click on based on what others have clicked on?

@dushyantsharma49123 жыл бұрын
Google uses Page Rank algorithm for listing the search results and I think that they use hybrid system for recommending similar searches.

There must be a better way to do this...I don't identify with most of what the "big sites" recommend me. KZbin, for example, keeps recommending me chess related videos when I've never watched anything remotely chess related as far as I know. I guess this must mean that my tastes are somehow adjacent to the subject of chess, but it sounds like the system would yield better results overall if it could somehow realize that I am not responding to that particular subject.
@wnwillyndirangu8 жыл бұрын
+Erik Pontifex your concern is genuine but another aspect of machine learning (which is basically a field of AI) is to try and predict things you might like just like netflix . one way of doing this is grouping people (clustering ) with similar tastes together . This might be what youtube does and it just might happen that the cluster you are in consists of people who like chess thus the recommendations.
