The restriction will be removed automatically once this activity stops. Recently, a research team led by Professor Kang Zhao at the University of Iowa has developed a better algorithm for dating sites to link up singles.Initial data analysis highlights the problem of over-recommending popular users, a standard problem for collaborative filtering applied to product recommendation, but more acute in people-to-people recommendation.We address this problem with a two-stage recommender process that employs a Decision Tree derived from interactions data as a “critic” to re-rank candidates generated by collaborative filtering.This model is then used to predict items (or ratings for items) that the user may have an interest in.These approaches are often combined (see Hybrid Recommender Systems).There is, of course, a glaring difference between dating and the other matchings — the "targets" being chosen are human beings, and they can choose whether or not to reply.If I want to watch "House of Cards" on Netflix, Kevin Spacey cannot say no to me.
but we have temporarily restricted your access to the Digital Library.The evaluation showed that, had users been able to follow the top 20 recommendations of our best method, their success rate would have improved by a factor of around 2.3.A common perception is that online dating systems “match” people on the basis of profiles containing demographic and psychographic information and/or user interests.In the above example, requires a large amount of information on a user in order to make accurate recommendations.
This is an example of the cold start problem, and is common in collaborative filtering systems. Moreover, in contrast to typical product recommender systems, it is unhelpful to recommend popular items: matches must be extremely specific to the tastes and interests of the user, but it is difficult to generate such matches because of the two way nature of the interactions (user initiated contacts may be rejected by the recipient).

The main problem to be solved is that matches must be highly personalized.The algorithm first compares me to other users, seeing how much overlap there is between the movies I watched and rated highly, and the movies that the other users watched and rated highly.
