摘要:

随着在线社交媒体的流行,用户的社会联系被广泛研究并用于提高推荐系统的性能。在本文中,我们探讨了使用双曲几何的社会推荐。我们提出了双曲社会推荐(HSR),一个新的社会推荐框架,利用双曲几何,以提高性能。在双曲空间的帮助下,HSR可以学习高质量的用户和项目表示,以便更好地建模用户-项目交互和用户-用户社交关系。通过一系列广泛的实验,我们表明,我们提出的HSR优于它的欧几里得同行和国家的最先进的社会网络的点击率预测和top-K推荐,证明了社会推荐的有效性,在双曲空间。

英文摘要:

With the prevalence of online social media, users' social connections have been widely studied and utilized to enhance the performance of recommender systems. In this paper, we explore the use of hyperbolic geometry for social recommendation. We present Hyperbolic Social Recommender (HSR), a novel social recommendation framework that utilizes hyperbolic geometry to boost the performance. With the help of hyperbolic spaces, HSR can learn high-quality user and item representations for better modeling user-item interaction and user-user social relations. Via a series of extensive experiments, we show that our proposed HSR outperforms its Euclidean counterpart and state-of-the-art social recommenders in click-through rate prediction and top-K recommendation, demonstrating the effectiveness of social recommendation in the hyperbolic space.
