An Improved Heuristic Attribute Reduction Algorithm Based on Informa- tion Entropy in Rough Set
At present, in rough set theory there are two kinds of heuristic attribute reduction algorithms, one is based on discernibility matrix, the other is based on mutual information. But if these algorithms are applied to the non-core information system, there will be much problems, such as too much calculation, excessive reduction, or insufficient reduction. So we propose an improved heuristic attr...
متن کاملAn Improved Attribute Reduction Algorithm based on Granular Computing
Abstract: Granular computing is a new intelligent computing method based on problem solving, information processing and pattern classification. Granular computing based attribute reduction method is an important application of Granular computing. These algorithms are mostly based on reduction core. However, some information systems may have no reduction core, especially in the actual applicatio...
متن کاملAn Attribute Reduction Algorithm Based on Rough Set Theory and an Improved Genetic Algorithm
Because the existing attribute reduction algorithms based on rough set theory and genetic algorithm have the main problems: the complexity in calculating fitness function and slow speed in convergence. An attribute reduction algorithm based on rough set theory and an improved genetic algorithm is proposed in this paper. In order to simplify the calculation of fitness function under the conditio...
متن کاملAn improved attribute reduction algorithm based on mutual information with rough sets theory
There aren’t core attributes in some information system, but the core attributes are the basis of attribute reduction algorithm based on mutual information, in order to solve the problem of a new attribute importance degree one new method on the basis of mutual information is proposed in the paper, which consists of its own information entropy and mutual information. Then the corresponding heur...
متن کاملAn Improved Entropy-based Endpoint Detection Algorithm
It is found that the detection using basic spectral entropy becomes difficult and inaccurate when speech signals are contaminated by high noise. This paper presents an improved entropy-based algorithm. The way to compute spectral probability density function of entropy is altered by the introduction of a positive constant. The modification improves the discriminability between speech and noise ...
