So, "deep learning" is the idea of doing representation learning via a chain of learned feature extractors. It's all about describing some input data via *deep hierarchies of features*, where features are *learned*. A further question is then: is the brain "deep learning"?

On the surface, that seems relatively reductionist, but something like that that is the kind of complexity that composes well at massive scales. I don't think we can comprehend the vast oceans within oceans of complexity 100 trillion synapses give rise to.

As far as genealogy goes you may want to have a look at the affiliations on the backprop nature paper. Or the wonderful PDP books, which read remarkably modern today. I think the genealogy is shared, and that should be celebrated. Interdisciplinary science is great!

Humans clearly have some genetically coded feature extractors, and even genetically coded behavioural packages.

I always agreed that deep learning is to neuroscience what modern aviation is to a bird (Minus the fact that deep learning didn't supersede it's analogue counterpart)

I wonder, when at last people will notice Numenta and Jeff's neocortex HTM?
