torch_geometric.datasets.JODIEDataset

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

Bases: InMemoryDataset

来自“JODIE: Predicting Dynamic Embedding Trajectory in Temporal Interaction Networks”论文的时间图数据集。

Parameters:

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

  • name (str) – 数据集的名称 ("Reddit", "Wikipedia", "MOOC", 和 "LastFM").

  • 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)
