Automated thresholding for unsupervised neurofeedback sessions

Automatisierte schwelle für unüberwachte nervenrückkopplungssitzungen

Seuillage automatisé pour des sessions de rétrocontrôle neuronal non supervisées

Abstract

The invention relates to a method for biofeedback training of a subject, said method comprising iteratively obtaining a series of biomarkers, each biomarker being representative of a bio-signal of the subject on a first time window; computing an intermediate threshold Thr intermediate ( t ) based on the series of biomarkers on a second time window, such that said intermediate threshold on said second time window could provide the subject with an expected reward ratio; computing a threshold Thr ( t ) as the weighted sum of the intermediate threshold Thr intermediate ( t ) and the threshold of the previous iteration Thr ( t -1); and reporting in real-time a reward to the subject based on the difference between the biomarker and the computed threshold Thr ( t ) ; wherein at each iteration the time windows are moved forward in time. The invention also relates to a system for implementing the method of the invention.
