Recommender system incorporating social network information-荆炳义 (香港科技大学)

主  题: Recommender system incorporating social network information 

内容简介: We propose the so-called NetRec method in recommender system by incorporating the network information into collaborative filtering (CF). This results in a sharper error bound than previous literature under reasonable assumptions. It is also shown that the combination of the network-related penalty and the nuclear norm penalty gives better estimates than those achieved by any of them alone. The method has been shown to work well in simulations and some real data sets on Yelp.
