This study considers the problem of feature selection in in complete data. The intuitive approach is to first impute the missing values, and then apply a standard feature selection method to select relevant features. In this study, we show how to perform feature selection directly, without imputing missing values. We define the objective function of the un certainty margin based feature selecti...

We examine the Differential Grammar , a representat ion designed to discr iminate which of a set of eonfusable al ternat ives is most likely in the context it occurs in. This approach is useful whereever uncer ta inty may exist about the ident i ty of a token or sequence of tokens, including in speech recognition, optical character recognition and machine t ransla t ion. In this paper our appl ...

The complexity of probabilistic reasoning with Bayesian networks has recently been proven to be NP complete So reducing the complexity of such networks is an active issue in uncer tainty reasoning Much work on such as compressing the probabilistic information for Bayesian networks and optimal approximation algorithm for Bayesian inference has been suggested In this paper we study a class of tra...

Equilibrium molecular dynamics simulation and the Green-Kubo formalismwere used to calculate self-diffusion coefficient, shear viscosity, and thermalconductivity for 30 different quadrupolar two-center Lennard-Jones fluids alongthe bubble line and in the homogeneous liquid. It was systematically investi-gated how anisotropy, i.e. elongation, and quadrupole momentum influence the...

A method is presented for matching two scene descr ip t ions, each of which consists of a set of measured feature vectors w i th estimated uncer ta int i e s . The two scenes d i f f e r by a transformation that depends on a few unknown parameters. The method performs a search by sequent ia l ly matching features of one scene to those of the other scene, solv ing for the transformation paramete...

Kikuchi-Fujimoto disease (KFD) benign, systemic lymphadenitis, self limiting disease Pathologists Kikuchi and Fujimoto in Japan in 1972. The incidence of KFD is unknown. KFD is up to 4 times commoner in women. It presents as lymphadenopathy mainly involving the cervical region, but can occur in any lymph node and even in extra nodal sites. Fever is associated with lymph node enlargement in half...

This paper assumes the cell formation problem as a distributed decision network. It proposes an approach based on application and extension of information theory concepts, in order to analyze informational complexity in an agent- based system, due to interdependence between agents. Based on this approach, new quantitative concepts and definitions are proposed in order to measure the amount of t...

by Michael Lippman It is always unsettling to enter the theater for a performance and f ind the actors already on stage; one can almost be int imidated, as i f the audience has interrupted a ritual which was going on before it entered and now must pay humble t r ibute. The black-tight white-face figures seemed unaware o f an expectant audience as they went through their "Free Exerc i s e . ' 1 ...
