Probability on Graphs Random Processes on Graphs and …

If the two principal characters in these notes are random walk and per-colation, they are only part of the rich theory of uniform spanning trees, self-avoiding walks, random networks, models for ferromagnetism and the spread of disease, and motion in random environments. This is an area that

The Gaussian distribution

We may extend the univariate Gaussian distribution to a distribution over d-dimensional vectors, producing a multivariate analog. The probablity density function of the multivariate Gaussian distribution is p(x j ; ) = N(x; ; ) = 1 Z exp 1 2 (x )> 1(x ) : The normalization constant Zis Z= p det(2ˇ 1) = (2ˇ)d=2(det ) =2: 1

More on Multivariate Gaussians

A vector-valued random variable x ∈ Rn is said to have a multivariate normal (or Gaus-sian) distribution with mean µ ∈ Rnn ++ 1 if its probability density function is given by p(x;µ,Σ) = 1 (2π)n/2|Σ|1/2 exp − 1 2 (x−µ)TΣ−1(x−µ) . 2 Gaussian facts Multivariate Gaussians turn out to be extremely handy in practice due to the ...
