摘要:

金融交易构成实体之间的连接,并通过这些连接,一个大规模的异构加权图制定。在这个不断更新的互动迷宫中,存在着各种基于相似性的模式,可以提供对金融体系动态的洞察。在当前的工作中,我们提出了在可扩展的动态设置中应用图表示学习,作为以有意义和鲁棒的方式捕获这些模式的一种手段。我们继续对潜在轨迹进行严格的定性分析,以从所提出的表示及其随时间的演变中提取真实世界的见解,据我们所知,这是金融领域的第一次。潜在空间的变化与已知的经济事件有关,特别是最近的COVID-19疫情对消费模式的影响。捕获这些模式表明通过合并潜在图表示为金融建模增加了价值。

英文摘要:

Financial transactions constitute connections between entities and through these connections a large scale heterogeneous weighted graph is formulated. In this labyrinth of interactions that are continuously updated, there exists a variety of similarity-based patterns that can provide insights into the dynamics of the financial system. With the current work, we propose the application of Graph Representation Learning in a scalable dynamic setting as a means of capturing these patterns in a meaningful and robust way. We proceed to perform a rigorous qualitative analysis of the latent trajectories to extract real world insights from the proposed representations and their evolution over time that is to our knowledge the first of its kind in the financial sector. Shifts in the latent space are associated with known economic events and in particular the impact of the recent Covid-19 pandemic to consumer patterns. Capturing such patterns indicates the value added to financial modeling through the incorporation of latent graph representations.
