0. 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 ?

  • Option : 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.
