Answer:

Given that:

Neutral network:

The artificial neural network implements all properties of biological neural networks in a computer.

• The processing elements in the artificial neural network are similar to the biological neurons.

o Each element (neuron) in the artificial neural network accepts multiple inputs and results in a single output value (either 0 or 1)

o Each element in the artificial neural network contains a numeric threshold value, and the incoming line contains weights that represent stimuli

• The output value of an element is based on the threshold value and the incoming weight

• If the sum of Incoming weight is greater than or equal to the threshold value of an element, then the element will be fired

• Consider the given neural network.

o The node NI receives two inputs, the weights of the two inputs are 1 and 2 respectively.

o The node N2 receives two inputs, the weights of the two inputs are 1 and 2, respectively.

o Based on the given weights, the input lines 2 and 4 cause the node N3 to fire

• Because the incoming weight of the line 2 simulation m 2 +2 = 4, which is greater than the threshold value of node N3

• Therefore, the following event causes node N3 to fire

NI 2 N3 3 N2 2

• And the incoming weight of the line 4 simulation m 2 +2 = 4, which is greater than the threshold value of node N3

• Therefore, the following event causes node N3 to fire

NJ 2. 2 N2 3 N2 2- 2
