信号交替算法方法来绘制信号三角: 积极和消极。这是因为正弦电压被比作一个固定电压。

最小二乘法一般是用来拟合直线和一些线性数据的，就是用一条直线来尽可能的表达若干的点的趋势，当然直线穿过所有的点是最好的，但往往有误差存在，所以拟合出的直线要求误差最小.设这些点为(x1,y1),(x2,y2)....(xn,yn).拟合直线为y=kx+b.-Ordinary least squares method is used to fit a straight line and a number of linear data, that is, as far as possible with a straight line to the point of the expression of a number of trends, of course, a straight line through all the points is the best, but often there is a margin of error, Therefore, a straight line fitting the requirements of the smallest error. established for these points (x1, y1), (x2, y2 )....( xn, yn). fitting straight line y = kx+ b.

该算法实现了数据挖掘中基于候选集的频繁项的挖掘，对于训练数据的处理，我们使用一个hashmap表来模拟初始阶段的数据，让后根据支持度来从候选集中找出满足支持度的频繁项，然后进行下一层的频繁项挖掘
