【摘要】 表示是将客观数据或现象利用数值或者编码方式进行描述,从而使其在一定数学含义框架下彼此相关的过程。在模式识别领域中,表示问题至关重要,其效果将直接影响后续步骤的复杂程度与分类性能。本文主要对表示在模式识别中的作用、表示问题的理解、表示的原则进行分析并对表示的方法进行归类描述,其目的是吸引更多的同行开展深入的表示问题研究,促进模式识别理论和方法的进步。更多还原

【Abstract】 The representation is an important issue in pattern recognition, which describes a real world observation as numerical value or encodes and makes the observations relative in mathematical framework. The effect of representation influences the com- plexity and performanceofpost-processing directly.Representations’ situationin pattern recognition,the comprehension and formula of the representation and method for typical representations are disscussed in this paper. It is concluded that although there are vari- ous method for representation, it is still an issue should be improved and studied.更多还原
