- Confusion matrix of classified discrete feature windows (each 1-s wide) showing the predicted behaviours (rows; originating from random forest classification) against the observed reference behaviours (columns; originating from the focal video data) for accelerometers mounted on the head in 2015 (50 Hz). Behaviours included Rest, Alert, Presenting/Nursing, Locomotion, Comfort Movement, and Flippering pup. Values across the diagonal (bold italic) represent those behaviours that were correctly identified, true positives, while those in italics represent false positives (rows) and false negatives (columns)
