torch_geometric.datasets.EllipticBitcoinDataset

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

Bases: InMemoryDataset

椭圆比特币数据集，包含来自 “比特币中的反洗钱：使用图卷积网络进行金融取证实验” 论文的比特币交易数据。

EllipticBitcoinDataset 将比特币交易映射到属于合法类别（交易所、钱包提供商、矿工、合法服务等）与非法类别（诈骗、恶意软件、恐怖组织、勒索软件、庞氏骗局等）的真实实体。

存在203,769个节点交易和234,355个有向边支付流，其中2%的节点（4,545个）被标记为非法，21%的节点（42,019个）被标记为合法。其余交易未知。

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)
