Here's a very cool Google Creative Labs experiment that used tSNE to organize thousands of bird chirps/songs/calls. The result is an interactive map that groups similar bird sounds (click/tap to play any of the sounds):

I feel like these kind of cool tech demos paired with a highly motivated and technically savvy phd student would lead to some interesting models in research papers with accompanying demos.

On a related note, there's an app that will identify bird species based on photos that you upload (http://merlin.allaboutbirds.org/photo-id/), and it's powered by "Visipedia", a collaboration between a Caltech and Cornell research group (https://vision.cornell.edu/se3/projects/visipedia/?__hstc=75...).

I remember how nascent the tech was when they first started releasing it in 2011ish and it's incredible how good it is now. Really awesome stuff.

That is really cool. Also, if you click and drag you get the sound of a roller coaster.
