WGS84toBJ54xy

国际上机器学习方面的教材，得到国际上的公认 (Aspects of machine learning materials, get international recognition)

G729编码和解码的Matlab源程序 调用方法： 1.需要编码时，在 Matlab命令行下输入"G729code(speech)"(请务必保证 speech是已经存在在 Matlab工作区的一个行向量，其中是语音数据)，然后你会在你的文件夹下看到一个"coding.bit"的文件。 2.需要解码时，把"coding.bit"的文件复制到"G729 decoder"的目录下，在Matlab命令行下输入"G729decodermain"，然后你会在文件夹下看到"syn_speech.wav"，那就是重构语音。 enjoy it! (G729 encoding and decoding of the Matlab source code to call methods: 1. The need for coding at the Matlab command line, enter )

说明：  基于小波变化的一些程序，有效的提高语音识别(Some of the procedures based on wavelet transform, effectively improve the speech recognition)

说明：  用三层感知器实现数据分类。该感知器无反馈，使用2-2-1结构(Sensor data with a three-tier classification. The sensor without feedback, using the 2-2-1 structure)

完整的决策树算法，训练决策树，修剪决策树(机器学习)(decision tree)

清华大学王书宁老师凸优化课程原对偶内点法求解二次规划问题(code using primal dual interior point method to solve the problem of quadratic programming in convex optimization class by Shuning Wang, Tsinghua univ.)

ldpc码的matlab仿真程序，信息序列较小，但仿真效果好。(LDPC codes matlab simulation program, the information sequence of smaller, but better simulation effect.)

说明：  matlab数学手册，比较适合有基础的读者使用，适合数学分析或者数据分析(matlab mathematics manuals, more suitable for readers based on the use of mathematical analysis or data analysis for)

用MATLAB实现了基于pca的特征提取方法，有效地完成了识别，是识别的经典例子(Pca-based implementation using MATLAB feature extraction methods, efficient completion of the identification is to identify the classic example of)

经验模态分解，matlab实现，用于信号的降噪处理，提取特征值处理等经验模态分解，这是用汉语注释的EMD程序，很不错的。％ 语法 ％ IMF = EMD(X) ％ IMF = EMD(X,..., Option_name ,Option_value,...) ％ IMF = EMD(X,OPTS) ％ [IMF,ORT,NB_ITERATIONS] = EMD(...) (This is annotated in Chinese EMD procedures, very good. Syntax IMF = EMD (X) IMF = EMD (X ,..., Option_name, Option_value ,...)
