PQ

说明：  画出函数的ROC曲线，precision/recall 曲线(function [prec, tpr, fpr, thresh] = prec_rec(score, target, varargin) PREC_REC- Compute and plot precision/recall and ROC curves.)

经过一周的深入学习和参考本站的资料，对K均值进行了改进。可以针对简单的二维的矩阵进行任意中心个数的聚类，并且能够生成图像。(K-means clustering experiments)

使用matlab实现对excel文档的写操作，以写学生成绩报告为例(Use matlab to achieve excel document write operation to write the report as an example of student achievement)

无监督混合高斯模型（GMM）的EM估计，含两篇IEEE论文的源码(This is a set of MATLAB m-files implementing the mixture fitting algorithm described in the paper M. Figueiredo and A.K.Jain, "Unsupervised learning of finite mixture models", IEEE Transaction on Pattern Analysis and Machine Intelligence, vol. 24, no. 3, pp. 381-396, March 2002.)

通过学习BP神经网络技术，对手写数字进行识别，基于结构的识别法及模板匹配法来提高识别率。(Through the study of BP neural network technology, digital handwriting identification, structure-based identification method and template matching method to improve the recognition rate.)

各种数字调制的一种产生方法，很有意思的哦......(A variety of digital modulation method for forming a very interesting ...... oh)

说明：  ADRC 主要功能是结合PID控制器来抵抗干扰，可运行(ADRC The main function is to combine with PID controller to resist interference and operate)

噪声背景下的语音端点检测和语音增强算法，在信噪比很低的强航空噪声背景下，(aviation noise background voice endpoint detection and voice enhancement algorithms, and very low signal to noise ratio in the strong aviation background noise, particularly effective)

说明：  这是我帮一个同学写的关于KDJ线的程序，实现KDJ五天均线得出最优买入点。(This is a student I helped to write the procedure on KDJ line to achieve a five-day moving average KDJ get the optimal timing.)
