3.6. Consider the network shown in Figure 3.14, with the initial weight and basis are chosen as W1 = 1, bl = 1, w2 =-2, b2 = 1. The activation function () is set the same as Exercise 3.2. Assume the input and the desired responses of the network are x 1, d 1, respectively. 1. Calculate the total instantaneous error energyE. 2. Compute OE/wi based on the result of 1. 3. Recompute OE/OW1 by using the backpropagation algorithm and compare the result with (2)
