Essential sets and support sets for stochastic processes
نویسنده
چکیده
In recent articles the author used his work in measure and integration to produce a new universal concept of stochastic processes. This concept leads, for the first time, for a stochastic process to a natural notion of essential subsets in the path space. But there remained some contrast to the traditional treatment, for example because for the Poisson process the set of càdlàg paths is not an essential subset. The present article is an attempt to harmonize the two approaches, in that it proposes and studies, for a stochastic process, besides the notion of essential sets the somewhat weaker but reasonable notion of support sets.

Application of tests of goodness of fit in determining the probability density function for spacing of steel sets in tunnel support system
One of the conventional methods for temporary support of tunnels is to use steel sets with shotcrete. The nature of a temporary support system demands a quick installation of its structures. As a result, the spacing between steel sets is not a fixed amount and it can be considered as a random variable. Hence, in the reliability analysis of these types of structures, the selection of an appropri...
متن کاملSeparated finitely supported $Cb$-sets
The monoid $Cb$ of name substitutions and the notion of finitely supported $Cb$-sets introduced by Pitts as a generalization of nominal sets. A simple finitely supported $Cb$-set is a one point extension of a cyclic nominal set. The support map of a simple finitely supported $Cb$-set is an injective map. Also, for every two distinct elements of a simple finitely supported $Cb$-set, there exists...
متن کاملA New Approach for Knowledge Based Systems Reduction using Rough Sets Theory (RESEARCH NOTE)
Problem of knowledge analysis for decision support system is the most difficult task of information systems. This paper presents a new approach based on notions of mathematical theory of Rough Sets to solve this problem. Using these concepts a systematic approach has been developed to reduce the size of decision database and extract reduced rules set from vague and uncertain data. The method ha...
متن کاملBayesian Inference in Trigonometric Support Vector Classifier
In this paper, we apply popular Bayesian techniques on support vector classifier. We propose a novel differentiable loss function called trigonometric loss function with the desirable characteristics of natural normalization in the likelihood function, and describe a Bayesian framework in stationary Gaussian stochastic processes. In this framework, Bayesian inference is used to implement model ...
متن کاملHow Can a Global Social Support System Hope to Achieve Fairer Competiveness?; Comment on “A Global Social Support System: What the International Community Could Learn From the United States’ National Basketball Association”
Ooms et al sets out some good general principles for a global social support system to improve fairer global competitiveness as a result of redistribution. This commentary sets out to summarize some of the conditions that would need to be satisfied for it to level up gradients in inequality through such a social support system, using the National Basketball Association (NBA) example as a point ...
