implementation of ART for classification of letters

Comparison of two survival curves can be done using a statistical hypothesis test called the log rank test. It is used to test the null hypothesis that there is no difference between the population survival curves (i.e. the probability of an event occurring at any time point is the same for each population).

这是一个混沌理论中重要的细胞神经网络的程序。通过曲线很容易看到奇妙的超混沌吸引子(Chaos Theory important cellular neural network procedures. Curve it is easy to see the mysterious super-chaotic attractor)

adboost算法的一个例子。在Kearns和Valiant在1989年大作中指出了这种算法的可行性。而后，Freund在 1990年以及他和Schapire在 1994-1996年提出了boosting整个算法思路，似乎这种算法走到 了实际应用的开端。然而直到AdaBoost被viola在其人脸识别系统中运用(2001Viola和 Jones)，这种方法才彻底开始暴火.(An example adboost algorithm. Kearns and Valiant pointed at the feasibility of this method in 1989 masterpiece. Then, Freund and Schapire he made in 1990 and in 1994-1996 the idea of ​ ​ boosting the entire algorithm, this algorithm seems to come to the beginning of the practical application. However, until the use of AdaBoost is viola (2001Viola and Jones) in its face recognition systems, this approach was completely start a fire storm.)

m序列的生成代码，使用程序在matlab上生成m序列，引用后实现其他功能(M sequence generation code, use the program in matlab generated on the m sequence, after the reference to implement other functions)

应用条件随机场知识对图像进行分割，场景理解。(Application CRFs knowledge of image segmentation, scene understanding.)

spectrum sensing for cognitive radio using energy detection

ecomsed 前后处理功能包,不用我多说的啦(no)

OFDM系统下的信道估计,LS和MMSE算法的区别，比较仿真图像(OFDM systems under channel estimation, the difference between LS and MMSE algorithm to compare simulation image)

ABC_FDTD_Die(T) Implements simulation of a Gaussian Pulse over T time steps. ABC are for free space. If boundaries are in the Dielectric medium then the ABC fail. Dielectric medium begin and end can be specified with the code(ABC_FDTD_Die (T) Implements simulation of a Gaussian Pulse over T time steps. ABC are for free space. If boundaries are in the Dielectric medium then the ABC fail. Dielectric medium begin and end can be specified with the code)
