Parametric statistical models of continuous or discrete valued data are often not properly normalized, that is, they do not integrate or sum to unity. The normalization is essential for maximum likelihood estimation. While in principle, models can always be normalized by dividing them by their integral or sum (their partition function), this can in practice be extremely difficult. We have been developing methods for the estimation of unnormalized models which do not approximate the partition… CONTINUE READING
