OGB/ogbg-ppa
收藏资源简介:
`ogbg-ppa`数据集是从1,581个物种的蛋白质-蛋白质关联网络中提取的一组无向蛋白质关联邻域,涵盖了37个分类群。该数据集是Open Graph Benchmark的一部分,旨在用于分类群预测任务,即37类多分类任务。数据集包含158,100个图,平均每个图有243.4个节点和2,266.1条边,平均节点度为18.3,平均聚类系数为0.513。每个图的数据包括边的索引、边的属性、标签和节点数量。数据集已按照PyGeometric版本提供的数据分割进行划分。
The `ogbg-ppa` dataset is a collection of undirected protein association neighborhoods extracted from protein-protein association networks of 1,581 species, covering 37 taxonomic groups. It is part of the Open Graph Benchmark, targeting taxon prediction tasks, a 37-class multi-classification problem. The dataset contains 158,100 graphs, with an average of 243.4 nodes and 2,266.1 edges per graph, an average node degree of 18.3, and an average clustering coefficient of 0.513. Each graph includes edge indices, edge attributes, ground-truth labels, and the number of nodes. The dataset has been split according to the data splits provided in the PyGeometric version.
