k-means 算法的工作过程说明如下：首先从n个数据对象任意选择 k 个对象作为初始聚类中心；而对于所剩下其它对象，则根据它们与这些聚类中心的相似度（距离），分别将它们分配给与其最相似的（聚类中心所代表的）聚类；然后再计算每个所获新聚类的聚类中心（该聚类中所有对象的均值）；不断重复这一过程直到标准测度函数开始收敛为止。-k-means algorithm process as follows: First of all, the object data from the n choose k object as initial cluster centers and the remaining for the other object, then according to their cluster center with those of the similarity (distance) respectively assigned to them with the most similar (represented by cluster center) clustering obtained and then calculated for each new cluster center clustering (all objects in the cluster mean) repeated this process until the standard measure of function until the beginning of convergence.

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.

点到线段距离，在进行画图时，在选择线时有重要作用，-Point to a line distance

LEACH算法是一种无线传感器网络路由协议,leach协议算法基本思想是:以循环的方式随机选择簇头节点，将整个网络的能量负载平均分配到每个传感器节点中，从而达到降低网络能源消耗、提高网络整体生存时间的目的。仿真表明，与一般的平面多跳路由协议和静态分层算法相比，LEACH分簇协议可以将网络生命周期延长15%。
