Towards the automated localisation of targets in rapid image-sifting by collaborative brain-computer interfaces

Abstract

The N2pc is a lateralised Event-Related Potential (ERP) that signals a shift of attention towards the location of a potential object of interest. We propose a single-trial target-localisation collaborative Brain-Computer Interface (cBCI) that exploits this ERP to automatically approximate the horizontal position of targets in aerial images. Images were presented by means of the rapid serial visual presentation technique at rates of 5, 6 and 10 Hz. We created three different cBCIs and tested a participant selection method in which groups are formed according to the similarity of participants’ performance. The N2pc that is elicited in our experiments contains information about the position of the target along the horizontal axis. Moreover, combining information from multiple participants provides absolute median improvements in the area under the receiver operating characteristic curve of up to 21% (for groups of size 3) with respect to single-user BCIs. These improvements are bigger when groups are formed by participants with similar individual performance, and much of this effect can be explained using simple theoretical models. Our results suggest that BCIs for automated triaging can be improved by integrating two classification systems: one devoted to target detection and another to detect the attentional shifts associated with lateral targets.

Transfer Learning for Brain–Computer Interfaces: A Euclidean Space Data Alignment Approach

“…We used an RSVP dataset from PhysioNet 4 [9] for ERP classification. It contained EEG data from 11 healthy subjects upon rapid presentation of images at 5, 6, and 10 Hz [20]. Each subject was seated in front of a computer showing a series of images rapidly.…”

Presence of the Characteristics of Scalable 'Potential Molecule' for in EEG Signal

“…The reason for the use of this type of brain signals is that the human participant, every time, has to make quick decision based on cognitive tasks that they have never performed before and by making quick decision, specific neural pathway should be in place or created so as the human participant can perform well in that particular cognitive tasks or there is a change in neural pathway depending on the rapidly changing visual task and the associated actions that are required to respond to such task [3,4]. Therefore, these 13 concepts were applied on healthy human subjects' electroencephalogram (EEG) data while the human participants perform cognitive tasks [10].…”
