[Review] A Logical Calculus of the Ideas Immanent in Nervous Activity

This paper was published in 1943 by Warren S. McCulloch and Walter Pitts.1 It has been considered as the origin of the neural network field. It contains the background knowledge of biological neural networks of that time. Basing on these biological neural network structure details, authors discarded some "unimportant" or "uncomputable" structures and simplified some complicated structures then get an abstracted model that may have a simple function and could be analyzed mathematically.
