Aegis-GPU7.5 Node importance and network visualization
PageRank scores and ForceAtlas2 layouts.
Key points
PageRank scores a node higher when important nodes link to it. It is a classic measure of node importance (centrality).
What NVIDIA says (1)
“Find the PageRank score for every vertex in a graph.”
A graph layout assigns x and y positions to nodes for plotting. Force-directed layouts pull linked nodes together.
What NVIDIA says (1)
“ForceAtlas2 is a continuous graph layout algorithm for handy network visualization.”
Key terms
- cuGraph: A RAPIDS library for graph analytics on the GPU.
- PageRank: An importance score for each node, higher when important nodes link to it.
- Graph layout: Positions for drawing nodes so that the network structure is easy to see.
