Adaptive autoregressive identification with "Whale" forgetting function for Event Related Desynchronization/Synchronization analysis

Abstract

Adaptive Autoregressive Identification (AAR) with "whale" forgetting function is here proposed for Event Related Desynchronization/Synchronization (ERD/ERS) analysis. The new method, proceeding from a "pole-based" point of view, (i) is as good as the standard band-pass filtering approach for ERS estimation, (ii) automatically identifies the pole frequencies, and (iii) provides further information expressed by the pole frequency curves.
