中文说明：
由混合信号分离出原信号的算法，目前比较成熟的线性盲源分离算法有很多，FastICA是其中之一。独立成分分析ICA是一个在多领域被应用的基础算法。ICA是一个不定问题，没有确定解，所以存在各种不同先验假定下的求解算法。相比其他技术，ICA的开源代码不是很多。
English Description：
By separate the original signals mixed signal algorithm, the linear blind source separation algorithm has many more mature, FastICA is one of them.Independent component analysis (ICA is a based algorithm has been applied in many field.ICA is an uncertain problems, no solution is determined, so there are a variety of different algorithm of a priori assumptions.Compared with other technologies, open source code is not a lot of ICA. fast independent component analysis.
