Item-based collaborative filtering algorithm is one of the main collaborative filtering algorithms. However, its recommendation quality is seriously influenced by the sparsity of user ratings. To solve the problem, an improved item-based collaborative filtering algorithm based on group weighted rating is...

Item-based算法详细过程 (1)相似度计算 Item-based算法首选计算物品之间的相似度,计算相似度的方法有以下几种: 1.基于余弦(Cosine-based)的相似度计算,通过计算两个向量之间的夹角余弦值来计算物品之间的相似性 2.基于关联(Correlation-based)的相似度计算,计算两个向量之间的Pearson-r关联度 3. 调整的余弦(Adjuste...
