Series

Integer values indicating the considered time series (there are 62 time series in the dataset).

Integer values indicating the temporal indexes of the observations.

Class

Details

The column Value is the concatenation of 62 time series taking six categorical values (sleep stages). The column Class is formed by the integers 1 and 2 indicating that there are 2 different classes in the database. Each class is associated with a sleep disorder (class 1 refers to nocturnal frontal lobe epilepsy, while class refers 2 to REM behavior disorder). For more information, see López-Oriona et al.
