METHOD, NON-TRANSITORY COMPUTER READABLE MEDIUM AND APPARATUS FOR AROUSAL INTENSITY SCORING

摘要

A computerized method comprises statistically analyzing, using one or more processors, at least one section of a digitally recorded electroencephalography (EEG) signal that comprises an arousal segment to determine, for the arousal segment, at least one of amplitude and power at different frequencies as a function of time; selecting specified features from the results of the analysis and normalizing the selected features; and assigning, using one or more processors, an intensity scale value to the arousal segment based on the normalized selected features and a reference data set, the reference data set comprising normalized features corresponding to the normalized selected features and being generated based on a plurality of EEG signals comprising arousal segments to which intensity scale values have been assigned based on a visual inspection of the EEG signals.
