McCulloch-Pitts neuron

McCulloch-Pitts neuron

(artificial intelligence)The basic building block ofartificial neural networks. It receives one or more inputsand produces one or more identical outputs, each of which is asimple non-linear function of the sum of the inputs to theneuron. The non-linear function is typically a threshhold orstep function which is usually smoothed (i.e. a sigmoid) tofacilitate learning.
