乳腺癌（BRCA TCGA Pan-Cancer Atlas）数据集包含来自 cBioPortal 的具有生存信息和基因表达数据的患者，以及来自 Pathway Commons 的这些节点之间的生物相互作用网络。 该数据集包含1,082名患者的基因特征，以及每位患者的总生存时间（以月为单位）作为标签。

关于如何使用此数据集的预处理和示例模型代码可以在这里找到。

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)

  • pre_filter (callable, optional) – A function that takes in an torch_geometric.data.Data object and returns a boolean value, indicating whether the data object should be included in the final dataset. (default: None)

  • force_reload (bool, optional) – Whether to re-process the dataset. (default: False)
