From: Classification and automatic scoring of arousal intensity during sleep stages using machine learning
Receiver operating characteristic (ROC) curves of arousal intensity level classification results by sleep stages. Since all metric values are equal to the maximum value of 1.00 in the N3 stage, the graph of the stage was skipped for better representation. (a) ROC curves of arousal intensity level classification results from the REM stage. (b) ROC curves of arousal intensity level classification results from the N1 stage. (c) ROC curves of arousal intensity level classification results from the N2 stage.
