Consider the directed network G = (V,E) with N = 5 nodes and L = 8 links, in which node 1 points to nodes 2 and 3, node 2 points to node 4, node 3 points to nodes 2 and 4, node 4 points to node 2, and node 5 points to nodes 3 and 4. (e) Calculate the eigenvector centrality ; of each node of the network and rank the nodes, from the most to the least central, according to their eigenvector centrality. To obtain the eigenvector centrality, start from the initial guess x (0) = +1 where 1 is the N-dimensional column vector of elements 1; = 1 Vi = 1,2..., N, and use the following recursive rule x(n) = Ax (n-1), where n Є N. Finally calculate the eigenvector centrality x; of each node i of the network from the limit (n) Ꮖ ; = lim x+-u x Στ Can you obtain the same result by directly calculating eigenvalues and eigenvectors of the adjacency matrix?

Transcribed Image Text:Consider the directed network G = (V,E) with N = 5 nodes and L = 8 links, in which
node 1 points to nodes 2 and 3, node 2 points to node 4, node 3 points to nodes 2 and
4, node 4 points to node 2, and node 5 points to nodes 3 and 4.
(e) Calculate the eigenvector centrality ; of each node of the network and rank the
nodes, from the most to the least central, according to their eigenvector centrality.
To obtain the eigenvector centrality, start from the initial guess x (0) = +1 where
1 is the N-dimensional column vector of elements 1; = 1 Vi = 1,2..., N, and use
the following recursive rule
x(n) = Ax (n-1),
where n Є N. Finally calculate the eigenvector centrality x; of each node i of the
network from the limit
