摘要:

基于邻域的协同过滤算法通常对每个用户或项目采用固定的邻域大小,尽管用户组或项目组可以根据用户的偏好具有不同的长度。在本文中,我们提出了一个扩展的非个性化推荐的基础上的置信区间和层次聚类生成最佳规模的用户组。评估表明,该技术优于传统的推荐算法在四个公开可用的数据集。

英文摘要:

Neighborhood-based collaborative filtering algorithms usually adopt a fixed neighborhood size for every user or item, although groups of users or items may have different lengths depending on users' preferences. In this paper, we propose an extension to a non-personalized recommender based on confidence intervals and hierarchical clustering to generate groups of users with optimal sizes. The evaluation shows that the proposed technique outperformed the traditional recommender algorithms in four publicly available datasets.
