Fig 2. Classification accuracy of the proposed model for the N-class problem using CLO-43SD.

The proposed model is compared against a baseline method which uses standard MFCC features. For additional context the preliminary result reported in [15] for a flight call dataset with a similar number of species (42) is also provided, however it is not directly comparable to the baseline and proposed model since the study used a smaller dataset of 1180 samples. The error bars represent the standard deviation over the per-fold accuracies (for [15] there is only a single value).
