说明：  一个matlab写的bpANN程序，参数优化采用交叉验证办法.(Write a matlab bpANN process parameter optimization using cross-validation approach.)

matlab basic exercise

使用Matlab编程实现GMM算法,不调用已有函数库，对大量点进行分类(LM algorithm using Matlab programming, do not call the existing library, a large number of points to classify)

机器学习》课上的作业，PCA和LDA降维，尽管网上很多，但很少注释，另外细节上也没注意。这里有很详细的注释。另外还附上一个Naive贝叶斯分类器，大家可以作比较。附带的图像包是OLR人脸。ReducedDim为想要提取的特征数，不是百分比！-" (Machine learning" classes on the homework, PCA and LDA dimensionality reduction, even though a lot of online, but few notes, on the other did not pay attention to details. Here there is a very detailed notes. In addition, attach a Naive Bayesian classifier, we can compare. Fringe image packages are OLR )

td-scdma链路仿真中的qpsk调制仿真程序，有详细的解释。(td-scdma Link Simulation qpsk modulation simulation program, a detailed explanation.)

这个包包括了一个多类代价敏感学习方法Rescalenew。这是一个通用的方法,如instance-weighting, sampling, threshold-moving等。(This package includes a multi-class cost-sensitive learning method Rescalenew. This is a general method which can be realized in many ways such as instance-weighting, sampling, threshold-moving, etc. This package includes five implementations of the method, that is, instance-weighting+C4.5, over-sampling+C4.5, under-sampling+C4.5, threshold-moving+NN and threshold-moving+PETs (probability estimation trees). )

假设检验例题 7.1 设总体 ，其中参数 ， 为未知，试指出下面统计假设中哪些是简单假设，哪些是复合假设： （1） ； （2） ； （3） ； （4） ； （5） . 解：（1）是简单假设，其余位复合假设 (Hypothesis testing for Example 7.1 overall, including parameters, is unknown, pointed out that the following statistical hypothesis test which is a simple assumption, which is a compound hypothesis: (1) (2) (3) (4) (5). Solution : (1) is a simple assumption, the remaining bit composite hypothesis)

本程序使用matlab编写，采用非加权最小二乘法进行相位展开，得到展开的相位(This program is written by matlab。 using the method of non-weighted least squares, the phase would be unwrapped)
