粒度计算的理论、模型与方法

The Theory Models and Approaches of Granular Computing

粒度计算(GranularComputing,GrC)是信息处理的一种新的概念和计算范式,覆盖了所有有关粒度的理论、方法、技术和工具的研究.它是词计算理论、粗糙集理论、商空间理论、区间计算等的超集,也是软计算科学的一个分支.它已成为模糊的、不完整的、不精确的及海量的信息处理的重要工具和人工智能研究领域的热点之一.另着重介绍了粒度计算的研究现状、基本问题、主要模型与方法,并提出了进一步的研究方向.

Granular computing is an emerging conceptual and computing paradigm of information processing. Just as a great umbrella,it may be regarded as a label of theories,methodologies,techniques,and tools that make use of granules,i. e.,groups,classes,or clusters of a universe. 'GrC' is a superset of the theory of fuzzy information granulation,rough set theory,the theory of quotient space and interval computing etc, which is a branch of soft computing science. It plays a important role in information processing for fuzzy, uncertainty,partial truth and unnumbered and becomes one of the main study stream in A I. It lays stress on the introduction of the research status,the basic problems and main approaches of GrC. Finally,the further investigation objects are proposed.
