遗传算法求tsp问题及其matlab代码实现 主程序中有一rand( seed ,n) n 为某一整数, 这是设置随机数发生器的种子，这样实际上规定了随机数发生的方式，因此后面的随机数其实都是定下来的，这样所有人就可以看到同一结果, 可注释掉此行，那么每次的结果就不一定再相同了. (Genetic algorithm to solve the TSP problem and the matlab code to achieve A Rand main program ( seed , n) n as an integer, which is the setting of the random number generator seed, this actually provides a random number generating means, so the random number behind actually are determined, so that everyone can see the same results, can comment out this line, then each time the results do not necessarily the same. )

文章展示了基于高斯混合模型的语音频谱预测方法。频谱预测可能在传包过程中预防丢包这方面起到大作用。期望最大化算法用两倍或三倍的连续语音因素来测试模型。模型被用来设计第一，儿等指令预测量。预测表用频谱分配状态来估计并和一个简单的参考模型对比。最好的预测表得到一个平均频率扭曲值是0.46dB小于参考模型(This paper presents methods for speech spectrum prediction based on Gaussian mixture models. Spectrum prediction may be useful in a packet transmission system where the sensitivity to packet losses is a major problem. Models of speech are trained by the Expectation Maximization algorithm using pairs, triples etc. of consecutive cepstral vectors. The models are used to design first, second etc. order predictors. The prediction schemes are evaluated using the spectral distortion criterion and compared to a simple reference method. The best prediction scheme obtains an average spectral distortion that is 0.46 dB less than for the reference method. )
