The theoretical foundation for a number of model selection criteria is established in the context inhomogeneous point processes and under various asymptotic settings: infill, increasing domain combinations these. For Poisson we consider Akaike's information criterion Bayesian criterion, particular identify process analogue ‘sample size’ needed criterion. Considering general derive new composite...

In many applications, large volumes of time-sensitive textual information require triage: rapid, approximate prioritization for subsequent action. In this paper, we explore the use of prospective indications of the importance of a time-sensitive document, for the purpose of producing better document filtering or ranking. By prospective, we mean importance that could be assessed by actions that ...

This is a survey of the information criterion approach to model selection problems. New results about context tree estimation and the estimation of the basic neighborhood of Markov random fields are also mentioned. 1. The model selection problem Let a stochastic process {Xt, t ∈ T } be given, where each Xt is a random variable with values a ∈ A, and T is an index set. The joint distribution of ...
