Abstract

Many phenomena in quantum mechanics and theories of modern dynamics systems are represented in topological spaces with high dimensions and modern information systems use topological space as mathematical model which express it. As far as linking between dimensions of topological spaces and accuracy of approximation are not taught before and mentioned only in Pawlak space. The topology associated with Pawlak approximation space has a zero dimension, the generalized space generated by general binary relation is not generally of zero dimension. The purpose of this paper is to compute dimensions of topologies associated with information systems which resulted from general relations and connection between the dimension of topologies and approximation accuracy of uncertain concepts. Examples for topologies resulted from various subsets of features are given. We use the concept of topology, boundary, basis, the upper and lower approximation for calculation approximation accuracy. Also, we construct topologies from data table (information systems) by using general relations and compute dimensions of these topologies for its importance in finding connection between accuracy of approximation and dimensions.
