> It's also very commonly observed that, for instance, the intensity of a stimulus is encoded not in the amplitude of a particular neuron's response but rather in the frequency of a neuron's firing. This was actually mentioned by Geoff Hinton in his deep learning coursera lectures and the reason why his RBM's were outputting binary signals rather than float values -- the timing was more important than the values. It made a lot of sense when he talked about it. I saw this back in 2012. I assumed this was commonly understood now, but I guess not?
