The tri-axial ACC demo dataset from white stork (Ciconia ciconia) (data accessible from the AcceleRater website: http://accapp.move-ecol-minerva.huji.ac.il/) was measured at 10.54 Hz. Forty tri-axial measurements, totalling 3.8 seconds, were used to form a behaviour segment. The dataset includes 1746 segments each forming a row in the dataset. Each row contains 121 columns. The first 120 columns are ACC measurements from three orthogonal axes, arranged as x, y, z, x, y, z, ...,x, y, z. The final column is of type character containing the corresponding behaviour. The dataset contains 5 different behaviours including "A_FLIGHT" - active flight (77 cases), "P_FLIGHT" - passive filght (96), "WALK" - walking (437), "STND" - standing (863), "SITTING" - sitting (273).
