torch_geometric.datasets.BitcoinOTC

class BitcoinOTC(root: str, edge_window_size: int = 10, transform: Optional[Callable] = None, pre_transform: Optional[Callable] = None, force_reload: bool = False)[source]

Bases: InMemoryDataset

来自“EvolveGCN: Evolving Graph Convolutional Networks for Dynamic Graphs”论文的Bitcoin-OTC数据集，包含138个顺序时间步的谁信任谁网络。

Parameters:

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

  • edge_window_size (int, optional) – 图中边自初始创建以来存在的窗口大小。 (默认值: 10)

  • 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)
