From: Animal-borne acoustic data alone can provide high accuracy classification of activity budgets
Illustration of (A) the sound spectrogram along with (B) the manual identification and labelling of activities and (C, D) the predictions before and after revision. Three main activities were defined and included in the budget (flying, diving and floating on the water) and two additional transition activities (entering water and taking off) were used exclusively for the revision algorithm. These transition activities were used to confirm dive and flying events, and then merged into their corresponding main activity. Isolated segments were removed and relabelled and predictions were smoothed using a moving median over 6 segments
