A perceptron has three inputs X₁, X₂, X3 and a bias input fixed to 1. It classifies using a threshold step function [h(z)= 1 if z>0; else 0] as its activation function. Initialize the corresponding weights as follows: w₁ = 0.7, W₂ = 0.2, W3 = 0.9. Let the learning rate be 0.2 and bias weight w. be -0.7. W₁ X₁ W₂ X₂ 0 W3 W₂₁ X3 +1 Apply the perceptron learning rule with the above input and with desired output 0. What are the new weights after this update ? Note: The output 0 here is fixed and may or may not be the answer to the previous question.

Question
A perceptron has three inputs X₁, X₂, X3 and a bias input fixed to 1. It classifies using a threshold
step function [h(z)= 1 if z>0; else 0] as its activation function. Initialize the corresponding weights
as follows: w₁ = 0.7, W₂ = 0.2, W3 = 0.9. Let the learning rate be 0.2 and bias weight w. be -0.7.
