NettetA diagram of a linear threshold unit. This example has two inputs that are summed by the combiner and then put through a function. Notice the weights on each input. NettetNeurons, modeled as linear threshold unit (LTU), can in theory compute all thresh- old functions. In practice, however, some of these functions require synaptic weights of arbitrary large precision. famous flying cars

"NettetIn artificial neural networks, the activation function of a node defines the output of that node given an input or set of inputs. A standard integrated circuit can be seen as a digital network of activation functions that can be "ON" (1) or "OFF" (0), depending on input. This is similar to the linear perceptron in neural networks.However, only nonlinear activation … " - Linear threshold unit
