一、概述所谓模式识別问题,就是对一群事物按某种需要分类,被分在同一类的事物间通常有某些共同的性质。例如识别英文字母,是要把待识的字母分到26个类中的某一类去。尽管不同的人写同一个字母会有千差万別,人还是很容易辩识它,但要把这个任务交给机器来做,那就相当困难了。模式识别的目的是把人类大脑将感觉(视觉、听觉等)得到的信息分类这种能力机器化,由计算机来实现。
First, an overview of the so-called pattern recognition problem, is a group of things according to a need classification, is divided into the same category of things generally have some common nature. For example, to identify English letters, it is necessary to classify the unknown letters into one of the 26 categories. Although different people write the same letter will be different, people can easily identify it, but this task to the machine to do, it is quite difficult. The purpose of pattern recognition is to machine the ability of the human brain to classify the information obtained by sensations (vision, hearing, etc.) by a computer.
