摘要
依据人们对数据的几何形态来推断变量间函数关系的原理 ,提出了色彩数据与Fuzzy嵌入文法等概念 ,并以此建立了利用计算机自动选择回归方程的文法Fuzzy模式识别方法。该模式识别方法中 ,色彩重心是在将原始数据赋予不同权重 (色彩度 )条件下得到的 ,信息损失少 ,更接近于人为描述曲线的心理特征 ;
According to the principle that we get the relationship of the function and the variate from the geometric figure of the data, put forward the concept of color data and Fuzzy imbedding grammar etc,and establish the identify of Fuzzy grammar that make use of the auto choice returning equation of the computer。The whole process of modle identify is a kind of process that imitate the experience identify of human.The quality of the identify result is based on two main conditions: the one is color filtering and the other is the modal rule of grammar .We get the color gravity center by giving the orignal data diffirent weight number.When we discribe a curve,the less information lose,the more near to the mental character .The regression modle is composed of a set of lingal variate by which we describe the curver's direction of increase or reduce.
