在收敛时,我们将超级节点上的预测集群标签从顶层图追溯到原始数据点,以获得最终的集群。 我们的方法基于训练集中地面实况标签建立的粒度级别收敛到一个集群。尽管身份与测试集不同,但它们足以在推理时隐式定义聚类的复杂性标准,而不需要单独的模型选择标准。 为了有效地运行 GNN 模型的多次迭代,我们设计了一个基本模型...
Graph Neural Networks (GNNs) have been shown to have a strong ability to address the problem of session-based recommendation with accurate item embedding. However, there are a lot of application scenarios that have already provided user profiles. We propose a model based on Hierarchical GNNs for...

This work addresses the importance of incorporating multi-scale information in image representation by proposing a novel approach utilizing hierarchical segmentation and graph neural networks (GNNs). The proposed model, named Hierarchical Image Graph with Scale Importance (HIGSI), leverages hierarchical segm...
Recently, there has been a promising tendency to generalize convolutional neural networks (CNNs) to graph domain. However, most of the methods cannot obtain adequate global information due to their shallow structures. In this paper, we address this challenge by proposing a hierarchical graph ...

In short, this hierarchical graph approach aims at modeling the natural PPI hierarchy with more effective and efficient structure perceptions. Here we describe a generic DL platform tailored for predicting PPIs, Hierarchical Graph Neural Networks for Protein–Protein Interactions (HIGH-PPI). HIGH-PPI ...
