Match List - I with List - II. Choose the correct answer from the options given below :List - I List - II (A) The activation function (I) is called the delta rule. (B) The learning method of perceptron (II) is one of the key components of the perceptron as in the most common neural network architecture. (C) Areas of application of artificial neural network include (III) is always boolean like a switch. (D) The output of the perceptron (IV) system identification and control.
(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
A perceptron computes a weighted sum of its inputs, passes it through an activation (step) function and is trained by adjusting its weights from the error.
(A) The activation function — together with the weights and bias, it is one of the key components of the perceptron, as in the most common neural network architectures: (A)-(II).
(B) The learning method of perceptron — weights are updated in proportion to the difference between target and actual output; this error-correction rule is called the delta rule (Widrow–Hoff): (B)-(I).
(C) Areas of application of artificial neural network include system identification and control, along with pattern recognition and forecasting: (C)-(IV).
(D) The output of the perceptron — a hard threshold gives 0/1 (or −1/+1), i.e. it is always boolean like a switch: (D)-(III).
Codes that make the activation function the delta rule, or the output an application area, mismatch these roles, so the other three codes fail.
(A)-(II), (B)-(I), (C)-(IV), (D)-(III) option is correct.
