Abstract: A method of estimating attention comprises: receiving encephalogram (EG) data corresponding to signals collected from a brain of a subject synchronously with stimuli applied to the subject. The EG data are segmented into segments, each corresponding to a single stimulus. The method also comprises dividing each segment of the EG data into a first time-window having a fixed beginning relative to a respective stimulus, and a second time-window having a varying beginning relative to the respective stimulus. The method also comprises processing the time-windows to determine the likelihood for a given segment to describe an attentive state of the brain.

Abstract: A method of training an image classification neural network comprises: presenting a first plurality of images to an observer as a visual stimulus, while collecting neurophysiological signals from a brain of the observer; processing the neurophysiological signals to identify a neurophysiological event indicative of a detection of a target by the observer in at least one image of the first plurality of images; training the image classification neural network to identify the target in the image, based on the identification of the neurophysiological event; and storing the trained image classification neural network in a computer-readable storage medium.

Abstract: A method of classifying an image is disclosed. The method comprises: applying a computer vision procedure to the image to detect therein candidate image regions suspected as being occupied by a target; presenting to an observer each candidate image region as a visual stimulus, while collecting neurophysiological signals from a brain of the observer; processing the neurophysiological signals to identify a neurophysiological event indicative of a detection of the target by the observer; and determining an existence of the target in the image is based, at least in part, on the identification of the neurophysiological event.
