Another difference between directed and undirected graphs is how paths and cycles are defined. A path is a sequence of vertices that are connected by edges, without repeating any vertex or edge.

Imagine a directed graphical model, akin to LinkedIn connections, where skills influence job opportunities, or vice versa. Unlike undirected models, these use directed acyclic graphs (DAGs) to ...

In a directed graph, an edge is typically represented as an ordered pair of vertices, such as (A, B), which means there is a directed edge from vertex A to vertex B.

Networks are graphs with weighted edges, where numerical values on edges specific quantities such as distance, time, or capacity. These can be either directed or undirected, and invaluable for ...

Hi DGL team, I had a quick query re. directed and undirected graphs in DGL. In the example referenced above for OGBN-ARXIV, the graph is defined as a directed graph originally, but one needs to make ...

Considering the image to be a directed graph with two nodes representing the source (object) and the sink ... Modeling the image as an undirected graph, $$ G = \langle V,E \rangle $$ ...

Methods: Directed graphs and their afferent/efferent capacities are produced by Markov modeling of the universal cover of undirected graphs simultaneously with the calculation of volume entropy. Using ...
