2. What is back propagation?A. It is another name given to the curvy function in the perceptron
B. It is the transmission of error back through the network to adjust the inputs
C. It is the transmission of error back through the network to allow weights to be adjusted so that the network can learn
D. None of the mentioned
3. What type of learning algorithm is used in EBPMLP?A. Supervised learning
B. Reinforcement learning
C. Active learning
D. Unsupervised learning
4. What effect does the learning rate have?A. Always increases the rate of change of weights
B. Always decreases the rate of change of weights
C. Increases the rate if value too high and decreases the rate if value too low
D. No effect
Hints:- Try these values and verify that you get the correct output.
W11 = W12 = W21 = W22 = 1,
b1 = 1.5, b2 = 0.5 and b3 = 0.5,
V1 = -2 and V2 = 1.
W11 = 1, W12 = -1, W21 = 2 and W22 = 3,
b1 = b2 = b3 = -1,
V1 = -1 and V2 = -2,
Learning rate = 0.75 and No. of iterations = 10,00,000.
