WebIn 1956, mathematician Stephen Kleen described McCulloch-Pitts neural models with an algebra notation that he penned ‘regular expressions’. Influenced by Kleen’s notion, in 1968, mathematician and Unix pioneer, Ken Thompson, implemented the idea of regular expressions inside the text editor, ‘ed’. His aim was that ed users would be ... The first artificial neuron was the Threshold Logic Unit (TLU), or Linear Threshold Unit, first proposed by Warren McCulloch and Walter Pitts in 1943. The model was specifically targeted as a computational model of the "nerve net" in the brain. As a transfer function, it employed a threshold, equivalent to using the Heaviside step function. Initially, only a simple model was considered, with binary inputs and outputs, some restrictions on the possible weights, and a mo…
