WebOne of the difficulties with the McCulloch-Pitts neuron was its simplicity. It only allowed for binary inputs and outputs, it only used the threshold step activation function and it did not incorporate weighting the different inputs. In 1949, Donald Hebb would help to revolutionize the way that artificial neurons were perceived.
