一、用GA直接训练BP网络的权重算法
主程序：gafault.m 它包括以下子程序：
1. BP网络初始化：nninit.m――给出P，T，R，S1，S2；
2. 适应值计算函数：gabpEval.m；
3．将遗传算法的编码解码为BP网络所对应的权值、阈值函数：gadecod.m；
二、用GA先求BP网络的权重，再用纯BP直接训练BP的混合GA－BP算法
主程序：gabpfault.m 它包括以下子程序：
1. 网络初始化：nninit.m――给出P，T，R，S1，S2；
2. 适应值计算函数：gabpEval.m；
3．将遗传算法的编码解码为BP网络所对应的权值、阈值函数：gadecod.m；
三、纯BP

（2）bpfault.m 在MATLAB6.5上 为后来所加
(First, the direct training of BP network with GA the weight algorithm
Main program: gafault.m It includes the following routines:
1. BP network initialization: nninit.m-- given P, T, R, S1, S2
2. Fitness calculation functions: gabpEval.m
3. Of genetic algorithms for the BP network codec corresponding weights, the threshold function: gadecod.m
Second, with the GA first aim at the weight of BP network, and then direct the training of pure BP mixture of BP algorithm GA-BP
Main program: gabpfault.m It includes the following routines:
1. Network initialization: nninit.m-- given P, T, R, S1, S2
2. Fitness calculation functions: gabpEval.m
3. Of genetic algorithms for the BP network codec corresponding weights, the threshold function: gadecod.m

HDF5TOOLS
Prior to release 0.40, H5DUMP relied upon HDF5INFO to provide the
metadata necessary, but now it now relies entirely on the low-level
interface. Since it is not backwards compatible with prior releases,
the old version is provided in the obsolete directory.

2013TSP
说明： 通过并行压缩进行二维信号压缩，提出了一种利用并行压缩传感技术对二维信号进行压缩的新方案。根据这个原理，译码器的重新构造可以并行进行。通过对二维信号进行某些排列，可以确保所有列具有大致相同的密度级别，并且可以使用相同的测量矩阵进行采样。这样可以避免二维信号的矢量化，从而大大减小测量矩阵的尺寸。我们证明，如果排列良好，重建均方误差的上限会更紧。为了说明这一方案，我们将其应用于视频压缩并使用不同帧的排列有两种：参考帧的基于Z字形扫描的排列和非参考帧的基于块测试的排列。仿真结果表明，在相同的压缩比下，峰值信噪比比比在无置换情况下可提高3-7db左右。(we propose a new scheme to compress 2D signals using parallel compressed sensing. According to this seheme, the reeonstruction at the decoder can be performed in parallel. By performing certain permutation on a 2D signal, all columns are insured to have approximately the same density level and can be sampled using the same measurement matrix. In this way, vectorization of a 2D signal can be avoided, and thus the size of the measurement matrix can be dramatically reduced. We prove that with a good permutation, we can have a tighter upper bound on reconstruction mean square error. To illustrate this scheme, we apply it to video compression and use
two kinds of permutations for different frames: the zigzag-scanbased permutation for reference frames and the block-test-based permutation for non-reference frames. Simulation results show that under the same compression ratio, the peak signal-to-noise ratio can be improved by approximately 3-7 dB compared to the case without permutation.)
