一种基于粗糙集和信息熵理论的属性离散化算法
AN ATTRIBUTE DISCRETISATION ALGORITHM BASED ON ROUGH SET AND INFORMATION ENTROPY THEORY
摘要
Abstract
After analysing and studying the necessity of continuous attributes processing in C5 algorithm and the shortcomings of discretisation method in C5 algorithm,we propose to adopt a discretisation method based on rough set theory-information entropy-discernible matrix discretisation (RSIEDM).By making use of the above three,the method can more reasonably and accurately discretise the continuous attributes,and enables the created decision tree to have better accuracy.Applying the method to optimising the statistics of lightning disaster and evaluating the losses of lightning disaster,the algorithm achieves desirable result.关键词
