torch_geometric.datasets.HM

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

Bases: InMemoryDataset

来自Kaggle H&M个性化时尚推荐挑战的异构H&M数据集。任务是基于之前的交易数据以及客户和产品元数据开发产品推荐。

Parameters:

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

  • use_all_tables_as_node_types (bool, 可选) – 如果设置为 True， 将使用事务表作为独立的节点类型。 (默认: False)

  • transform (callable, optional) – A function/transform that takes in an torch_geometric.data.HeteroData 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.HeteroData 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)
