摘要:

在许多场景中,捕获数据之间复杂的高阶交互是一项重要任务。一种常见的建模高阶相互作用的方法是使用超图,其拓扑结构可以用张量数学表示。现有的方法使用固定阶张量来描述整个超图的拓扑结构,忽略了不同阶相互作用的发散性。在这项工作中,我们考虑到这种分歧,并提出了一个多阶超图拉普拉斯算子和相应的全变差。将该全变分作为正则化项,利用其所包含的拓扑信息对超图信号进行平滑处理。这可以帮助区分不同阶的相互作用,并准确地表示高阶相互作用。

英文摘要:

Capturing complex high-order interactions among data is an important task in many scenarios. A common way to model high-order interactions is to use hypergraphs whose topology can be mathematically represented by tensors. Existing methods use a fixed-order tensor to describe the topology of the whole hypergraph, which ignores the divergence of different-order interactions. In this work, we take this divergence into consideration, and propose a multi-order hypergraph Laplacian and the corresponding total variation. Taking this total variation as a regularization term, we can utilize the topology information contained by it to smooth the hypergraph signal. This can help distinguish different-order interactions and represent high-order interactions accurately.
