本文的 item-to-item协同过滤 是基于 相似商品(item) 的 传统协同过滤 将user表示为一个N维向量,其中N是item的个数,向量的内容是 user购买了item 或者 user给item正负打分, 对于一些销量高的item,会给加权item的购买人数,1/buy_count,使稀有的item权重更大,每个向量是很稀疏的。 算法基于寻找最相似的user产生...
Item-to-item relationships are relationships between items. For example, you might have a relationship between the items in a bundle that are sold together for promotional purposes. In the example of items in a bundle, the individual items have a separate product Ids. Because the items are ...
本文所采用的方法是Item-to-Item CF,也叫做Item-Based CF,即关注用户对item的评分和购买行为,而不像Content-basedCF那样取关注物品内在属性上的关联。Item-Based CF根据用户购买或评级过的商品信息,匹配相似的商品,然后推荐给用户。 例如,上图中要为用户C推荐一个视频,用户C看过视频A,所以寻找与视频A相似的其他...
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),...
An approach is disclosed for providing item-to-item recommendations. The approach receives data for an item. The approach generates recommended candidate item data for the data of the received item. The approach generates feature data of the recommended candidate item data and the data of the ...
Cart or frequently bought together recommendations return items that are likely to be consumed together with the seed item(s). Get Similar Items Returns a list of item-to-item recommendations. Recommended items can be similar to the seed item or related in some way, based on the way data ...

与传统的协同过滤不同,该算法在用户数据有限的情况下也能运行良好,在少至2到3件商品的基础上,产生高品质的推荐。 连接: http://blog.sina.com.cn/s/blog_586631940100pduh.html http://www.xysay.com/amazon-item-to-item-collaborative-filtering-207.html...
Recommendation systems in large-scale online marketplaces are essential to aiding users in discovering new content. However, state-of-the-art systems for item-to-item recommendation tasks are often based on a shallow level of contextual relevance, which can make the system insufficient for tasks wh...
