From: Acoustic differentiation and classification of wild belugas and narwhals using echolocation clicks
Example average spectra for beluga (a,b) and narwhal (c,d) acoustic events that were correctly classified (a,c) and misclassified (b,d). The waveforms of the highest amplitude click for each event are provided. The beluga acoustic event in (b) was misclassified by only the RF model and the narwhal acoustic event in (d) was misclassified by both the RF and BANTER classification models.
