torch_geometric.transforms.LocalDegreeProfile

class LocalDegreeProfile[source]

Bases: BaseTransform

Appends the Local Degree Profile (LDP) from the “A Simple yet Effective Baseline for Non-attribute Graph Classification” paper (functional name: local_degree_profile).

\[\mathbf{x}_i = \mathbf{x}_i \, \Vert \, (\deg(i), \min(DN(i)), \max(DN(i)), \textrm{mean}(DN(i)), \textrm{std}(DN(i)))\]

to the node features, where \(DN(i) = \{ \deg(j) \mid j \in \mathcal{N}(i) \}\).
