(Nature Neuroscience . 1. Recurrent Networks. Some problems require previous history/context in order to be able to give proper output (speech recognition, stock forecasting, target tracking, etc.. One way to do that is to just provide all the necessary context in one "snap-shot" and use standard learning. Banafsheh. . Rekabdar. Biological Neuron:. The Elementary Processing Unit of the Brain.
