If my understanding is remotely correct, an RNN's view of a banana is basically like the face in Aphex Twin's Equation - [this video] (headphone users beware). No qualitative or quantitative information about the object, just a certain tone of integer triplets in a cacophony of noise. It seems like a many-dimensional view of the world around us is
