UGC-NET | UGC NET CS 2016 July – III | Question 66

  • Last Updated : 26 Apr, 2018

A perceptron has input weights W1 = – 3.9 and W2 = 1.1 with threshold value T = 0.3.
What output does it give for the input x1 = 1.3 and x2 = 2.2 ?
(A) – 2.65
(B) – 2.30
(C) 0
(D) 1


Answer: (C)

Explanation: According to given question w1 = – 3.9 and w2 = 1.1 and x1 = 1.3 and x2 = 2.2
weighted sum = w1 * x1 + w2 * x2 + . . . wn * xn
i.e. -3.9 * 1.3 + 1.1 * 2.2
= -5.07 + 2.42
= -2.65
Now we will compare the weighted sum -2.65 to the threshold 0.3.
-2.65 < 0.3
Then output will be zero.
So, option (C) is correct.
