torch_geometric.transforms.Distance

class Distance(norm: bool = True, max_value: Optional[float] = None, cat: bool = True, interval: Tuple[float, float] = (0.0, 1.0))[source]

将链接节点的欧几里得距离保存在其边属性中（功能名称：distance）。每个距离都会全局归一化到指定的区间（默认情况下为\([0, 1]\)）。

Parameters:

norm (bool, optional) – If set to False, the output will not be normalized. (default: True)
max_value (float, optional) – If set and norm=True, normalization will be performed based on this value instead of the maximum value found in the data. (default: None)
cat (bool, optional) – If set to False, all existing edge attributes will be replaced. (default: True)
interval ((float, float), optional) – A tuple specifying the lower and upper bound for normalization. (default: (0.0, 1.0))
