WebPurdue University WebWhile we normally represent multivariate Gaussians in terms of their mean and covariance, information form is often a useful alternative. The distribution is represented in terms of a quadratic "energy function." This representation is convenient for conditioning, and is the basis for Gaussian Markov random fields. Context

WebMar 5, 2016 · The 1D kernel is not obtained by sampling the Gaussian, but by integrating it over sub-intervals. For instance, instead of computing g ( x) = 1 2 π σ exp ( − x 2 2 σ 2) at t = 3, you integrate it over the interval [ − 3.5, − 2.5]. The result is in the following figure (pretty close, isn't?): The Matlab code goes like this:
