CHORUS-音频合唱功能

用C++实现WVD，其中用到汉明窗，是根据matlab时频分析工具包中的wvd变换改写成C++语言的，其中信号序列必须为2的整数倍，还用到快速傅里叶变换FFT

采用二进制Gray编码,采用基于轮盘赌法的非线性排名选择, 均匀交叉,变异操作,而且还引入了倒位操作!

快速幂级2 跟前面的是一起的-rapid power level with the previous two are together

该算法在某个再生核希尔伯特空间，在充分考虑领域间分布的均值差和散度差最小化的基础上，基于结构风险最小化模型，提出一种领域适应核支持向量学习机(Kernel support vector machine for domain adaptation, DAKSVM)及其最小平方范式，通过寻求某个特征变换，使得在确保训练数据的最大分割的同时，实现领域间不同分布之间的距离充分最小化，从而实现领域适应学习。

详细表述了分数阶傅立叶变换的离散实现，将现有的算法进行比较。-In this note we make a critical comparison of some matlab programs for the digital computation of the fractional Fourier transform that are freely available and we describe our own implementation that lters the best out of the existing ones. Two types of transforms are considered: First the fast approximate fractional Fourier transform algorithm for which two algorithms are available. The method is described in H.M. Ozaktas, M.A. Kutay, and G. Bozdagi. Digital computation of the fractional Fourier transform. IEEE Trans. Signal Process., 44:2141{2150, 1996. There are two implementations: one is written by A.M. Kutay the other is part of package written by J. O Neill. Secondly the discrete fractional Fourier transform algorithm described in the master thesis C . Candan.
