Simplified Page Rank 之马尔可夫模型对它的诠释

(PageRank.pdf 29页)

Markov model of simplified page rank: P⁽⁰⁾ = x⁽⁰⁾

P⁽⁰⁾ 代表初始状态概率(initial state probability)
x⁽⁰⁾ 代表初始Page rank
也就是说初始状态概率为页面的初始Page rank

A = W^T

W 是状态转移概率A的transpose
W is the transpose of the state transition probability A
之所以要W^T是因为想直接乘 P^(t)=WP^(t-1) （而不用去再转一道W 像这样：W^TP^(t-1)）
