FISM与SLIM不同之处在于,FISM求的是item-item相似性矩阵的分解,而SLIM直接求的是这个相似矩阵,相同的是它们在评估ruirui时,都不适用已知的评级信息ruirui。FISM与NSVD相同之处在于它们都是将item-item相似性矩阵分解为两个低秩矩阵,不同之处在于FISM是解决Top-N问题,NSVD解决的是评级问题,FISM不用已知的ruirui评...

The novelty of the algorithm is that it can (1) learn the global item similarity with latent factor models. (2) utilize effective pairwise ranking methods to deal with the item recommendation problems with implicit feedback. (3) assign different item weights on explicit feedback and implicit ...
