For example, simple filtering of time-signals is often very useful in this respect, and so is dimension reduction by principal component analysis (PCA); see ... in factor analysis and signal processing, and allows for a simple formulation of the noisy model. Thus, the noisy ICA model can be expressed as x = As + n (15.1) 293 Independent Com...
