Classes and their individual CV AUC scores. It seems Class 3 is significantly more difficult. I wonder if it is model dependent difficulty or just the data.

Looking at the data, I have only little hints on what differentiates 3 and 12. They seem pretty much the same with only a little difference. And that also does not help that the two seem to be in the same recordings a lot of times.

It is easier to notice when you listen to the files. Describing their cries doesn't translate well when I write it down, but maybe this image will help. Note that the Class 12 sounds are increasing in pitch, so in the spectograms they run from top-left to bottom-right.

Species 3 frequency range in labels:
\n1031.25 - 2812.5

\n

Species 12 frequency range in labels:
\n562.5 - 3281.25

\n

From this, it would seem like 12 has got a wider range in frequencies.
\nIn reality, I found that the two are almost the same in \"shape\" and also in range, the only difference being that 12 is a bit higher pitched than 3.

\n

But it also seems like that the pitch of them varies quite a lot in regards of how close they are.

Species/Class 12 also has a high-frequency component but I didn't label it since it's very difficult to distinguish from the similar part of species 3. The easily identifiable part is the lower-frequency section I labelled above.

This depends a lot on how you have labelled your data. Class 3 is highly common and appears in a lot of the TPs given to us by the organisers for other classes.
