The notion of Rough sets was introduced by Z Pawlak in his seminal paper of 1982 (Pawlak 1982). It is a formal theory derived from fundamental research on logical properties of information systems. Rough set theory has been a methodology of database mining or knowledge discovery in relational databases.

Abstract: Rough Set Theory is a mathematic tool which mainly deals with the uncertain knowledge. In this paper a new comprehensive evaluation model of low carbon economy based on rough set is formed. At last, the results of comprehensive evaluation of low carbon economy of 6 provinces based on this model are obtained which show this method is.


Research Paper On Rough Set Theory

After probability theory, fuzzy set theory and evidence theory, rough set theory is a new mathematical tool for dealing with vague, imprecise, inconsistent and uncertain knowledge. In recent years, the research and applications on rough set theory have attracted more and more researchers' attention. And it is one of the hot issues in the.

Research Paper On Rough Set Theory

Based on rough sets theory, from the view of Pansystems soft observation, two pieces of paradoxes in GIS are discussed in this paper. And then the reason and the resolution of the two paradoxes are presented. At the same time the relationship between the two paradoxes is analyzed and a further understanding of paradox and rough sets theory is acquired.

Research Paper On Rough Set Theory

Rough set theory has been studied further increasingly. Practical applications also conduce more to the development of rough set theory, such as the extended research on the equivalence relation. The model of rough set over dual-universes is an extended model of Pawlak rough set and this model depending on the relation themselves. The.

Abstract: Rough set theory is a mathematic method which analyses and treats vagueness and uncertainty, and offers an effective method to data fusion system. This paper compares rough set theory with D-S (Dempster Shafer) theory and fuzzy set theory, introduces some applications of rough set into data preprocessing, design of neural network architecture and data fusion system, discusses and.

Research Paper On Rough Set Theory

This article is the last of a series of three researches. The purpose of this research is to expose the results of using Dominance-based Rough Set Approach (DRSA) to help International organizations (both non-governmental organizations and governmental organizations) define poverty, identifying economical, sociological, political and technological strategic objectives for developing countries.

Research Paper On Rough Set Theory

INTRODUCTION Rough set theory is a new mathematical approach to imperfect knowledge. The problem of imperfect knowledge, tackled for a long time by philosophers, logicians, and mathematicians, has become also a crucial issue for computer scientists, particularly in the area of artificial intelligence.

Rough set theory proposed by the author in (1) presents still another attempt to this problem. The theory has attracted attention of many researchers and practitioners all over the world, who contributed essentially to its development and applications. Rough set theory has an overlap with many other theories. However we will refrain to.

Research on Extension of the Fuzzy Rough Set Theory. By Yu Zhang. Abstract. Abstract. With the probability rules and the degree of coverage of elements in the partition set, and the combination of the Fuzzy Set Theory and Rough Set Theory, a new extension of Fuzzy Rough Set theory was proposed. It is defined the maximum of Rough Set membership function, the minimum of Rough Set membership.

In this paper, rough set and decision tree combination were used to evaluate the productivity grade of soil in somewhere of Jilin province. The research data had a total of 161 records and 16 attributes. The paper used rough set to reduce the soil attributes, removed 5 redundant attributes and obtained the attributes reduction set, then decision tree method was used to construct the decision.

As an important processing step for rough set theory, attribute reduction aims at eliminating data redundancy and drawing useful information. Covering rough set, as a generalization of classical rough set theory, has attracted wide attention on both theory and application. By using the covering rough set, the process of continuous attribute discretization can be avoided. Firstly, this paper.

Set theory is a branch of mathematical logic that studies sets, which informally are collections of objects.Although any type of object can be collected into a set, set theory is applied most often to objects that are relevant to mathematics.
