Let there are two neurons X and Y which is transmitting signal to another neuron Z . Then , X and Y are input neurons for transmitting signals and Z is output neuron for receiving signal . The input neurons are connected to the output neuron , over a interconnection links ( A and B ) as shown in figure .
For above neuron architecture, the net input has to be calculated in the way.
I = xA + yB
where x and y are the activations of the input neurons X and Y. The output z of the output neuron Z can be obtained by applying activations over the net input.
O = f(I)
Output = Function ( net input calculated ) : The function to be applied over the net input is called activation function . There are various activation function possible for this.
