WebMar 29, 2024 · Graph and its representations. 1. A finite set of vertices also called as nodes. 2. A finite set of ordered pair of the form (u, v) called as edge. The pair is ordered because (u, v) is not the same as (v, u) in case of a directed graph (di-graph). The pair of the form (u, v) indicates that there is an edge from vertex u to vertex v. Webdgl.edge_subgraph. Return a subgraph induced on the given edges. An edge-induced subgraph is equivalent to creating a new graph using the given edges. In addition to extracting the subgraph, DGL also copies the features of the extracted nodes and edges to the resulting graph. The copy is lazy and incurs data movement only when needed.
