A Tensor Decomposition Approach to Noninvasive Atrial Activity Extraction in Atrial Fibrillation ECG

The proposed GMNS consists of the following two main contributions (i) we extend the concept of PCS (properly connected sequence) used in the MNS method in such a way one can

(2020) Prognostic value of the Residual Cancer Burden index according to breast cancer subtype: Validation on a cohort of BC patients treated by neoadjuvant chemotherapy.. PLoS

After an evaluation on synthetic signals, the L¨owner-BTD computed by LCAGL was applied to a population of 20 patients suffering from persistent AF, whose segments are characterized

In practice, the data matrix Y is only approximately given by (5), due to noise and imperfect modeling. Typically, an approximate BTD is computed by minimizing a measure of

The estimated signal obtained with the iterative version of the quasi-maximum likelihood based MaxViT method generally shows a higher SC than the estimate obtained from a

The inputs to the second processing stage are the nonventric- ular source components estimated by the first stage. The decision as to which components belong to the ventricular

We show the appropriateness of indepen- dent component analysis (ICA) to tackle this biomedical challenge when regarded as a blind source separation (BSS) problem. ICA is a

The performance of the coupled BTD for ECG source separation is now assessed in two consecutive synthetic AF segments by means of the normalized mean square error (NMSE) between
