基于耦合关系的加权Slope One算法
Weighted Slope One algorithm based on coupling relationship
摘要
Abstract
Slope One algorithm is a kind of collaborative filtering recommendation algorithm based on the item,it considers the coupling relationship between the attributes and the attributes of the project is not enough.Based on this,this paper proposed a weighted Slope One algorithm based on coupling relationship.The algorithm constructed the item properties coupling model and user attributes coupling relationship model,taking the user similarity and item coupling of weighted similarity of Slope One algorithm was improved.Validated on MovieLens dataset show that this algorithm has higher accuracy of recommendation.关键词
