Let:<br />
A ij = M ij + (1‐) /|S| if iS<br />
M ij<br />
otherwise<br />
A is stochastic!<br />
We have weighted all pages in the<br />
teleport set S equally<br />
Could also assign different weights to pages!<br />
Compute as for regular <strong>PageRank</strong>:<br />
Multiply by M, then add a vector<br />
Maintains sparseness<br />
