If the sources have symmetric distributions, we show in addition that L1-PCA is linked to kurtosis optimization. A number of numerical experiments illustrate the theoretical results and analyze the comparative performance of different algorithms for ICA via L1-PCA. Although our analysis is asymptotic ...
The use of PCA to model the low-frequency components of the eigenspace and ICA to model the high-frequency components of the residual space can improve the tolerance of the detection process toward variations in the illumination conditions and vehicle pose. For learning distinctive and discriminative...
diseases in our everyday life. Its importance cannot be overlooked in the field of medical research where each and every hospital, clinics and diagnostic centers use machine learning (PCA, ICA, Manifold dimensionality reduction) techniques for diagnosing diseases and prescribing patients with right ...

独立成分分析(ICA) ICA又称盲源分离(Blind source separation, BSS),它假设观察到的随机信号x服从模型 ,其中s为未知源信号,其分量相互独立,A为一未知混合矩阵。ICA的目的是通过且仅通过观察x来估计混合矩阵A以及源信号s。 大多数ICA的算法需要进行“数据预处理”(data preprocessing):先用PCA得到y,再把y的各个分...
