torch_geometric.datasets.DGraphFin

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

Bases: InMemoryDataset

DGraphFin网络来自 “DGraph: A Large-Scale Financial Dataset for Graph Anomaly Detection” 论文。 它是一个有向、无权重的动态图，包含数百万个 节点和边，代表了金融行业中一个真实的用户到用户的社交网络。 节点代表一个Finvolution用户，从一个用户到另一个用户的边意味着该用户将另一个用户视为紧急联系人。每条边都与一个 时间戳相关联，范围从1到821，以及一个紧急联系人类型，范围从0到11。

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)
