McCulloch-Pitts neuron
The basic building block of
{artificial neural networks}. It receives one or more inputs
and produces one or more identical outputs, each of which is a
simple non-linear function of the sum of the inputs to the
neuron. The non-linear function is typically a threshhold or
step function which is usually smoothed (i.e. a {sigmoid}) to
facilitate {learning}.
