基于GMM的说话人识别程序，提取梅尔倒谱特征进行训练(voice detection based on GMM)

动态因子模型，该模型可以有效对高维数据进行降维，将成百上千的数据信息浓缩在几个因子里面，即从一国许多经济时间序列数据中估计和解释驱动各变量波动的共同动态因子。 MATLAB代码(dynamic factor model, the model can be effective for high-dimensional data dimension reduction, condensed the hundreds of thousands of data in several factors, that is, from a country many economic time series data in the estimation and explain the common dynamic factors drive the variable volatility.MATLABcode)

MATLAB的源程序,包括产生随机传输数据data的子程序,eject_seq发射序列子程序,BPSK调制序列产生子程序,产生pn1序列的子程序,利用积分法实现BPSK解调,均衡pn1序列的子程序.(MATLAB source, including random data transmission of data subroutine, eject_seq launch sequence subroutine, BPSK modulation sequence generated subroutine, have Promoters sequence subroutine, use integral method to achieve BPSK demodulation, balanced Promoters sequence subroutine.)

说明：  多目标跟踪的matlab代码，其中背景差分法可以实现实时更新。该代码在检测与跟踪少量目标时效果很好,但是跟踪目标大于8后,效果下降很多。(Multi-target tracking matlab code)

说明：  遗传算法和BP神经网络组合，风速的超短期预测(The combination of genetic algorithm and BP neural network can predict wind speed)

粗糙集的基本算法，包括数据补齐，属性约简，值约简，规则生成，非常实用。(Rough set theory is a new mathematical approach to imperfect knowledge. The problem of imperfect knowledge has been tackled for a long time by philosophers, logicians and mathematicians. Recently it became also a crucial issue for computer scientists, particularly in the area of artificial intelligence. )
