Titel:
Graphical Models for Non-Negative Data Using Generalized Score Matching 
Abstract:
A common challenge in estimating parameters of probability density functions is the intractability of the normalizing constant. While in such cases maximum likelihood estimation may be implemented using numerical integration, the approach becomes computationally intensive. In contrast, the score matching method of Hyvärinen (2005) avoids direct calculation of the normalizing constant and yields closed-form estimates for exponential families of continuous distributions over Rm. Hyvärinen (2007) e...    »
