分类器是对每一个输入模式赋予一个类别名称的软件或硬件装置，而贝叶斯分类器是各种分类器中分类错误概率最小或者在预先给定代价的情况下平均风险最小的分类器。它的设计方法是一种最基本的统计分类方法

哈夫曼编码(Huffman Coding)以哈夫曼树─即最优二叉树，带权路径长度最小的二叉树，经常应用于数据压缩。-Huffman coding (Huffman Coding) ─ a Huffman tree that is optimal binary tree, with the right of the path length of the smallest tree, often used in data compression.

数据预测算法，主要是一元n次方程的回归预测实现。* 预测分析--本算法只适用于有明显线性趋势的数据 * 默认为一元二次曲线方程法 * * 本程序主要涉及有两个算法 * 1．用最小二乘原理找到线性方程组的系数和常数。 * 2．解线性方程组 * 本程序在解线性方程组中，由于考虑到收敛性问题未采用迭代法，而是采用Gauss-Jordan消去法来解决。-data prediction algorithm is mainly one yuan n equation forecast to achieve reunification.* Forecast and Analysis-- This algorithm applies only to clear linear trend data* default as a quadratic curve equation method** The procedure involves two main algorithm* 1. Using the principle of least squares linear equations to find the constants and coefficients.* 2. The solution of linear equations* The procedure for solving linear equations, due to convergence problems using iterative method, instead of using the Gauss-Jordan elimination method to solve.
