知识约简是机器学习,模式识别,信号处理等领域的主要问题之一。本文介绍了基于单调包含度的模糊决策信息系统的知识约简。证明了模糊决策信息系统的约简即是其对应信息系统的约简,从而为该种模糊决策信息系统的知识约简提供了简单直接的方法。
Knowledge reduction or feature selection is one of the main problems encountered in many areas such as machine learning, pattern recognition and signal processing. In this paper, method of reduction of information systems with fuzzy decisions based on hybrid monotonic fuzzy inclusion measures are introduced. The reducts of fuzzy decision information systems are proved to be those of crisp information systems.
