Unformatted text preview: Y 1 of the output neuron Y 1 . (ii) Find the required change Δ w for all the weights and threshold connected to Y 1 . (iii) Calculate the local gradient δ H 1 and δ H2 of the two hidden neurons. (iv) Find the required change Δ w for all the weights and thresholds connected to the two hidden neurons. (v) Update all the weights and thresholds in the multilayer perceptron. 2. Use the new weights and thresholds obtained in Q1 to find the new actual network output y Y 1 for the same inputs X 1 =0 and X 2 = 1. Is it closer to the target value 0.9?
