Re: I want to contribute MLlib two quality measures(ARHR and HR) for top N recommendation system. Is this meaningful?

Hey Deb, NDCG is the "Normalized Discounted Cumulative Gain" [1]. Another popular measure is "Expected Reciprocal Rank" (ERR) [2]; it is based on a probabilistic user model, where the user scans the presented list of search results or recommendations and chooses the first that is sufficiently rele

I want to contribute MLlib two quality measures(ARHR and HR) for top N recommendation system. Is this meaningful?

check it's quality. ARHR and HR are two good quality measures. I want to contribute them to spark MLlib. So I want to know whether this is meaningful? (1) If n is the total number of customers/users, the hit-rate of the recommendation algorithm was computed as hit-rate (HR) = Number of hits
