... by principal component analysis (PCA); see Sections 13.1.2 and 13.2.2. In noisy ICA, we also encounter a new problem: estimation of the noise-free realizations of the independent components (ICs). ... the noisy independent components, given by ~s i = s i + n i , and rewrite the model as x = A ~ s (15.3) We see that this is just the basic ICA model, with modified independent components. What...

... in Section 21.2.) Thus, those components that are not zero may not be very many, and the system may be invertible for those components. If we first determine which components are likely to be clearly ... independent components (ICs) by simply inverting the mixing matrix A . Therefore, even if we knew the mixing matrix exactly, we could not recover the exact values of the independent components...

... means that simply finding a matrix V so that the components of the vector z(t)=Vx(t) (18.3) are white, is not enough to estimate the independent components. This is because there is an infinity ... of different matrices V that give decorrelated components. This is why in basic ICA, we have to use the nongaussian structure of the independent components, for example, by minimizing the higher-orde...
