Real-world networks often exist with multiple views, where each view describes one type of interaction among a common set of nodes. For example, on a video-sharing network, while two user nodes are linked if they have common favorite videos in one view, they can also be linked in another view if they share common subscribers. Unlike traditional single-view networks, multiple views maintain different semantics to complement each other. In this paper, we propose MANE, a multi-view network embedding approach to learn low-dimensional representations. Similar to existing studies, MANE hinges on diversity and collaboration - while diversity enables views to maintain their individual semantics, collaboration enables views to work together. However, we also discover a novel form of second-order collaboration that has not been explored previously, and further unify it into our framework to attain superior node representations. Furthermore, as each view often has varying importance w.r.t. different nodes, we propose MANE+, an attention-based extension of MANE to model node-wise view importance. Finally, we conduct comprehensive experiments on three public, real-world multi-view networks, and the results demonstrate that our models consistently outperform state-of-the-art approaches.

协作度量学习(CML)最近成为推荐系统(RS)中的一种流行方法,缩小了度量学习和协作过滤之间的差距。遵循RS的惯例,现有的方法在其模型设计中利用唯一的用户表示。本文重点介绍了一个具有挑战性的情况下,用户有多个类别的利益。在这种情况下,我们认为,独特的用户表示可能会导致偏好偏差,特别是当项目类别分布不平衡。为了解决这个问题,我们提出了一种新的方法称为\textit{Diversity-Promoting Collaborative Metric Learning}(DPCML),希望考虑到通常被忽视的少数用户的利益。DPCML背后的关键思想是为系统中的每个用户包括多个表示集。基于此嵌入范式,用户对一个项目的偏好聚合从不同的嵌入之间的最小项目用户的距离用户嵌入集。此外,我们观察到,同一用户的嵌入的多样性在模型中也起着至关重要的作用。为此,我们提出了一个\textit{diversity control regularization}术语,以更好地适应多向量表示策略。从理论上讲,我们表明,DPCML可以很好地推广到看不见的测试数据,通过解决来自最小值的恼人的操作的挑战。在一系列基准数据集上的实验证明了DPCML的有效性。

无监督区域表示学习旨在从未标记的城市数据中提取密集有效的特征。虽然已经基于多个视图做出了一些努力来解决这个问题,但是现有方法在提取视图中的表示和/或合并来自不同视图的表示方面仍然不足。基于对比学习在表示学习中的成功,我们提出将其用于多视图区域表示学习,并设计了一个称为ReMVC(Region Embedding with Multi-View对比学习)的模型,该模型遵循两个指导原则:i)在每个视图中将区域与其他区域进行比较,以实现有效的表征提取; ii)在不同视图中将区域与自身进行比较,以实现跨视图信息共享。我们设计了视图内对比学习模块和视图间对比学习模块,前者用于学习不同的区域嵌入,后者作为软共正则化器来约束嵌入参数并在多视图间传递知识。我们在两个下游任务中利用学习到的区域嵌入,即土地使用聚类和区域流行度预测。大量的实验表明,我们的模型实现了令人印象深刻的改进相比,七个国家的最先进的基线方法,在土地利用聚类任务的利润率超过30%。
