A characterization of product-form exchangeable feature probability functions
We characterize the class of exchangeable feature allocations assigning probability Vn,k ∏k l=1WmlUn−ml to a feature allocation of n individuals, displaying k features with counts (m1, . . . ,mk) for these features. Each element of this class is parametrized by a countable matrix V and two sequences U and W of non-negative weights. Moreover, a consistency condition is imposed to guarantee that ...
متن کاملFeature Allocations, Probability Functions, and Paintboxes
The problem of inferring a clustering of a data set has been the subject of much research in Bayesian analysis, and there currently exists a solid mathematical foundation for Bayesian approaches to clustering. In particular, the class of probability distributions over partitions of a data set has been characterized in a number of ways, including via exchangeable partition probability functions ...
متن کاملExchangeable Choice Functions
We investigate how to model exchangeability with choice functions. Exchangeability is a structural assessment on a sequence of uncertain variables. We show how such assessments are a special indifference assessment, and how that leads to a counterpart of de Finetti’s Representation Theorem, both in a finite and a countable context.
متن کاملA. Economou: a Characterization of Product -form Stationary Distributions
We consider a general model for continuous-time Markov chains representing queueing systems in random environment. First we study the relationship between its equilibrium distribution and the Palm (or embedded) distributions at certain environmental change epochs. The results enable one to obtain the equilibrium distribution of the continuous-time model in terms of the equilibrium distribution ...
متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
