Table 4 Salient administered fractions derived from the CNN model. The average salient administered fraction (SAF) and standard deviation for true positive (SAF[+]) and true negative (SAF[−]) cases are listed in descending order based on the SAF[+] value. SAF[+] is calculated by summing up the time spent in a given neuropsychological test that intersects with a segment of time that is DE[+] salient and dividing by the total time spent in a given neuropsychological test. SAF[−] is calculated by summing up the time spent in a given neuropsychological test that intersects with a segment of time that is not DE[+] salient and dividing by the total time spent in a given neuropsychological test. The number of samples for SAF[+] and SAF[−] indicate the number of true positive and true negative recordings that contain each neuropsychological test
