= = Given a training sample x = (0.5, 0.5]", y = 1 for softmax regression of 3 classes (la- bels = {1,2,3}). Current parameters for the three classes are O2 = [0.9,-0.3, 0.5] T, O2 = (1.1, 0.7,0.8]T, O3 = [1.0,0.2, -0.9] T. = = = Page 1 of 2 (a) Calculate the cross-entropy cost function value for the training sample with the current parameters. (b) Update the parameters for 1 iteration with gradient descent with a learning rate of 0.5. Find the updated parameters O1, O2, O3 and show the details. (c) Find the cross-entropy cost values for the updated parameters from (b). Verify whether the cost function value has decreased or not.
