Reviewed exponential family basics, including regular families (families for which the domain Omega is an open set) and overcomplete, using the example of a multinomial distribution. Covered details on the Ising model, its extension to multinomial variables, and Gaussian MRF (focusing on Theta as the negative definite precision matrix), and the dimensions of such families.
