That's their post hoc, uncorroborated claim. It's easy to imagine many other possibilities; it could just be face saving. It could be Rush is taking the fall. etc.
p-e-w was just talking about this the other day in his Discord. seems doing the one neuron method is quite bad for KLD and that's why the newer techniques have stuck.
edit:
There appears to be more information in a variety of the creator's videos, but it looks like the projection from birdsong-to-3D is (probably simplified) taking the Mel spectrogram (40 features from this, unclear as to what they are) and passing it to PCA to get 3D vectors.
this looks awesome. i've been struggling with vector compression, and have been trying PCA + all sorts of rotations. looking forward to trying this out
nice writeup! looking forward to doing some more training as soon as i get some more data sorted. it'll be a custom arch, but i'll probably shoehorn it into unsloth for a speed boost.
