A subject-transfer framework for obviating inter- and intra-subject variability in EEG-based drowsiness detection

Abstract: Inter- and intra-subject variability pose a major challenge to decoding human brain activity in brain-computer interfaces (BCIs) based on non-invasive electroencephalogram (EEG). Conventionally, a time-consuming and laborious training procedure is performed on each new user to collect sufficient individualized data, hindering the applications of BCIs on monitoring brain states (e.g. drowsiness) in real-world settings. This study proposes applying hierarchical clustering to assess the inter- and intra-subject v… Show more

“…These studies show that DBN can predict around 85% of the variation in cognitive state. A subject-transfer framework for detecting drowsiness during simulated driving task based on EEG was also recently developed (Wei et al, 2018). In that study, response time was measured from the onset of a lane deviation to the onset of the response, which served as a behavioral assessment of drowsiness during the lane-keeping task.…”

“…Anatomic and environmental factors are attributed as the main causes of the typical difference of neural responses across individuals subjected to the same stimulus [5], [6], [7]. As a consequence, EEG data collected from different subjects commonly present shifts in the conditional distribution.…”
