Thanks for the quick response! Much appreciated!
I am a Machine Learning engineer and am trying to predict the sleep stage within a 30 second interval given the data present here https://www.sleepdata.org/datasets/shhs/files/polysomnography/edfs/shhs1
I can't find the sleep stage annotations (W, 1, 2, Deep Sleep, REM) in the .edf files. Can you please point me to the annotation?
