torch_geometric.datasets.LastFMAsia

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

Bases: InMemoryDataset

The LastFM Asia Network dataset introduced in the “Characteristic Functions on Graphs: Birds of a Feather, from Statistical Descriptors to Parametric Models” paper. Nodes represent LastFM users from Asia and edges are friendships. It contains 7,624 nodes, 55,612 edges, 128 node features and 18 classes.

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)
