fibrillation is a hazardous phenomenon in cardiac muscle and so any new work towards the understanding of this process is important to the development of new methods in diagnosis and therapy. in this work we have used surface and intra cardiac ecgs of patients with chronic atrial fibrillation (af). by means of the blind source separation (bss) algorithm, which is a well-known method in signal p...

A model for dynamic independent component analysis is introduced where the dynamics are driven by score of pseudo likelihood with respect to rotation angle innovations. While conditional second moments invariant rotations, higher not, which may have important implications applications. The maximum estimator shown be consistent and asymptotically normally distributed. simulation study reports go...
