Webfor what we call graph wavelets. Graph wavelets are quite general and flexible, and we explore some of the variations that are possible. Using measurements taken from an operating network (Abi-lene [2]) we show that graph wavelets can provide considerable leverage on whole-network traffic analysis. We show how graph wavelets can be used … 《Graph WaveNet for Deep Spatial-Temporal Graph Modeling》。这是悉尼科技大学发表在国际顶级会议IJCAI 2024上的一篇文章。这篇文章虽然不是今年的最新成果,但是有一些思想是十分值得借鉴的,所以放在这里给大家介绍。 See more 时空图建模是分析系统组件的空间关系和时间趋势的重要任务。假设实体之间的基础关系是预先确定的,则现有方法大多会捕获对固定的图结构中的空间依赖性。但是,显式图结构(关系)不一 … See more 给定图G=(V, E, A)及其历史S步图信号,我们的问题是学习能够预测未来T步图信号的函数f。 映射关系表示如下: See more small refrigerator that says coke
