ULA_信噪比

采用NLJ随机搜索的方法辨识一个以状态方法表示的非线性系统。选其初值 a1(0) =50 , a2(0) =100 , a3(0) =100 , a4(0) =50 , a5(0) =10 , 选范围为 r(1)(i)=0.5 a(0)(i) , 取数据长度 L ＝40, t =0.005 , 性能指标 J＝ 。迭代计算结果得 a 的估计值 1=17.6043243, 1=17.5977, 2=72.9573, 3=51.3014, 4=22.9889, 5=5.99965, J = 0.000000916 。-Using NLJ random search method to identify a method that the state of the nonlinear system. Election of its initial value a1 (0) = 50, a2 (0) = 100, a3 (0) = 100, a4 (0) = 50, a5 (0) = 10, choose the range of r (1) (i) = 0.5 a (0) (i), check data length L = 40, t = 0.005, performance index J =. Iterative calculation results have a estimated value of 1 = 17.6043243, 1 = 17.5977, 2 = 72.9573, 3 = 51.3014, 4 = 22.9889, 5 = 5.99965, J = 0.000000916.

资源描述语音识别中常用的参数有LPCC（线性预测倒谱系数）和MFCC（梅尔频率倒谱系数）。其中LPCC是基于人的发音模型建立的，是一种基于合成的参数。而MFCC是一种基于人耳的听觉特性提出的。大量研究表明，MFCC能够比LPCC更好的提高系统的识别性能。

应用背景你玩儿过扫雷游戏吧？Windows操作系统中带了这个小游戏，那个系统叫什么来着？在游戏中要想过关，就必须要在一个 NxM 的区域上找出所有的地雷。游戏过程中，计算机会在地图上显示一些数字从而帮助你确定哪里有地雷。关键技术Have you ever played the game? Windows operating system with this little game, the system called what? In the game to pass, it is necessary to find out all the mines in a NxM area. In the process of the game, the computer will show some numbers on the map to help you identify where you are.

本源码主要是提供了传统k-means算法以及利用近似k_d树算法进行加速的聚类算法。
