独立成分分析(ICA)是一种统计与计算技术,用于将多维数据集分解为相互独立的信号源。该方法广泛应用于信号处理、神经科学及数据分析等领域,旨在揭示复杂混合信号背后的原始独立源信息。
Independent Component Analysis (ICA) is a computational technique used to uncover hidden factors that underlie sets of random variables, measurements, or signals. ICA assumes that the observed data consists of linear mixtures of some unknown latent variables and tries to recover these underlying variables by minimizing their mutual statistical dependence, typically measured in terms of non-Gaussianity. This method is widely applied in signal processing, neuroscience, telecommunications, and other fields where separating mixed signals into independent sources can provide valuable insights.
