基于离散粒子群算法的粗糙集属性约简

摘要

提出了一种改进的属性约简启发式算法，首先介绍了离散粒子群算法的基本原理，构造出适应值函数，利用粒子群算法对信息系统进行属性约简，并通过实例验证该方法的有效性。%A kind of improved attribute reduction algorithm is proposed.Firstly,this paper introduces the basic principle of discrete particle swarm optimization algorithm,construct the fitness function,the use of particle swarm algorithm of information system for attribute reduction,and effectiveness of the method is verified by an example.
