Dukkipati, Ambedkar and Manathara, Joel George (2010) An Algebraic Implicitization and Specialization of Minimum KL-Divergence Models. In: 12th CASC International Workshop, SEP 06-12, 2010, Tsakhkadzor, ARMENIA, pp. 85-96.Full text not available from this repository.
In this paper we study representation of KL-divergence minimization, in the cases where integer sufficient statistics exists, using tools from polynomial algebra. We show that the estimation of parametric statistical models in this case can be transformed to solving a system of polynomial equations. In particular, we also study the case of Kullback-Csiszar iteration scheme. We present implicit descriptions of these models and show that implicitization preserves specialization of prior distribution. This result leads us to a Grobner bases method to compute an implicit representation of minimum KL-divergence models.
