Amazon.com Recommendations Item-to-Item Collaborative Filtering 发表于Industry Report(2003),是一篇essay,Greg Linden, Brent Smith, and Jeremy York, Amazon.com. 这篇文章属于推荐领域,介绍了Amazon在业务系统中真实使用的推荐算法(系统)。文章没有太多细节,但是介绍了几种推荐系统的常见算法,并提出了Item-based...
item-to-item collaborative filtering 能够应对大量数据场景,因为 item 之间的相似度具有持久性,可以预先离线进行计算。总结通过阅读论文,我感觉 collaborative filtering 在早期(2000年左右),专指 user-based CF,即通过找相似用户,用相似用户喜欢的物品作为推荐结果的方法。后来慢慢引入了 item-based(如本文所描述),...
看成搜索也就是user信息是query,item是doc, Item-to-Item Collaborative Filtering 传统协同过滤是寻找相似user,item-to-item协同过滤是对 user的item 和 相似item 进行match 离线维护一个item-item相似值矩阵
先来看看Amazon之前的传统的协同过滤(Collaborative filtering)是怎么做的。 首先呢,根据每个人买的书籍,我们可以将每个用户表示成一个向量。 例如, V(小明)=<1, 0, 1, 0, 1, 0> V(小张)=<0, 1, 1, 0, 1, 0> V(小李)=<1, 1, 0, 0, 0, 0> ...

To eliminate the most serious limitations of collaborative filtering, we have resorted to a well-known matrix factorization technique in the implementation of the item-based collaborative filtering algorithm, which has shown a good behavior in the TV domain. Every step in the development of this ...
