摘要:

目前,有一个研究趋势,利用神经结构的推荐系统。虽然已经提出了一些深度推荐模型,但大多数方法都过于简单,无法描述用户复杂的偏好。在本文中,细粒度的分析,用户的评分从多个角度来解释,在此基础上,我们提出了我们的神经架构。具体来说,我们的模型采用了几个连续的阶段来编码用户和项目到隐藏的表示。在一个阶段中,用户和项目从多个角度进行表示,在每个角度中,用户和项目的表示相互关注。最后,我们衡量的最终阶段的输出表示接近用户的评级。大量的实验表明,我们的方法实现了对基线的实质性改进。

英文摘要:

Currently, there starts a research trend to leverage neural architecture for recommendation systems. Though several deep recommender models are proposed, most methods are too simple to characterize users' complex preference. In this paper, for a fine-grain analysis, users' ratings are explained from multiple perspectives, based on which, we propose our neural architecture. Specifically, our model employs several sequential stages to encode the user and item into hidden representations. In one stage, the user and item are represented from multiple perspectives and in each perspective, the representations of user and item put attentions to each other. Last, we metric the output representations of final stage to approach the users' rating. Extensive experiments demonstrate that our method achieves substantial improvements against baselines.
