摘要:

我们提出了单纯神经网络(SNN),图神经网络的推广,生活在一类拓扑空间称为单纯复合体的数据。这些是图的自然多维扩展,不仅编码成对关系,还编码顶点之间的高阶交互-使我们能够考虑更丰富的数据,包括向量场和$n$ -fold协作网络。我们定义了一个适当的卷积概念,我们利用它来构建所需的卷积神经网络。我们测试的SNN的任务,填补缺失的数据合作复杂。

英文摘要:

We present simplicial neural networks (SNNs), a generalization of graph neural networks to data that live on a class of topological spaces called simplicial complexes. These are natural multi-dimensional extensions of graphs that encode not only pairwise relationships but also higher-order interactions between vertices - allowing us to consider richer data, including vector fields and $n$-fold collaboration networks. We define an appropriate notion of convolution that we leverage to construct the desired convolutional neural networks. We test the SNNs on the task of imputing missing data on coauthorship complexes.
