torch_geometric.datasets.EmailEUCore

class EmailEUCore(root: str, transform: Optional[Callable] = None, pre_transform: Optional[Callable] = None, force_reload: bool = False)[source]

Bases: InMemoryDataset

一个大型欧洲研究机构的电子邮件通信网络，取自“局部高阶图聚类”论文。 节点表示机构的成员。 一对成员之间的边表示他们至少交换了一封电子邮件。 节点标签表示成员属于42个部门之一。

Parameters:

  • root (str) – Root directory where the dataset should be saved.

  • transform (callable, optional) – A function/transform that takes in an torch_geometric.data.Data object and returns a transformed version. The data object will be transformed before every access. (default: None)

  • pre_transform (callable, optional) – A function/transform that takes in an torch_geometric.data.Data object and returns a transformed version. The data object will be transformed before being saved to disk. (default: None)

  • force_reload (bool, optional) – Whether to re-process the dataset. (default: False)
