IcaComonMatlab.tar
说明: 独立成分分析是近年来出现的一种强有力的数据分析工具。1994年由Comon给出了ICA的一个较为严格的数学定义,其思想最早是由Heranlt和Jutten于1986年提出来的。ICA从出现到现在虽然时间不长,然而无论从理论上还是应用上,它正受到越来越多的关注,成为国内外研究的一个热点。特别是从应用角度看,它的应用领域与应用前景都是非常广阔的,目前主要应用于盲源分离、图像处理、语言识别、通信、生物医学信号处理、脑功能成像研究、故障诊断、特征提取、金融时间序列分析和数据挖掘等。
ICA是一种用来从多变量(多维)统计数据里找到隐含的因素或成分的方法,被认为是主成分分析(Principal Component Analysis, PCA)和因子分析(Factor Analysis)的一种扩展。对于盲源分离问题,ICA是指在只知道混合信号,而不知道源信号、噪声以及混合机制的情况下,分离或近似地分离出源信号的一种分析过程。(Independent Component Analysis, ICA)

Comparison-of-Bayesian-and-fisher
训练错误率和交叉验证错误率相等,在样本比较大时,这个结果是可以预期的;训练错误率一般低于测试错误率,但是当样本数据比较少时,实验也出现了意外,样本多的那组测试错误率比样本少的训练错误率还要小;在本实验中,同组数据的交叉验证错误率比独立测试错误率高,这个反常现象是因为样本的原因所致,交叉验证的样本小,而独立测试时所用训练样本数目大,因而出现这种情况。分类线上,fisher准则是一条直线,而贝叶斯分类器实际上是一个类似椭圆的封闭曲线;很明显,贝叶斯分类器比fisher分类器要好。(Training error rate and cross- validation error rates are equal, the larger the sample , this result is to be expected training error rate is generally lower than the test error rate , but when comparing the sample data came from the experiment there was an accident, that more samples group test error rate less than the training sample error rate is smaller In this experiment, the same set of data cross-validation error rate than independent test error rate, this anomaly is because the sample of reasons , cross-validation sample is small,And independent testing large number of training samples used , resulting in this situation.Classification online , fisher criterion is a straight line , while the Bayesian classifier is actually a closed curve similar to elliptical It is clear that the Bayesian classifier is better than the fisher classifier .)
