1. Consider a neural network, which contains one hidden layer and an output layer with one output unit. Let the hidden units have negative sigmoid as the activation function, which is formulated as 1 n(v) 1 + exp(-1) and the output unit has a linear activation function in which the output is equal to the activation input). (a) Show that the derivative of the negative sigmoid obeys the following relation dn(v) dv = n(v)(1 + n(v)) (b) Let the cost...

1). The weight of w12 is damaged. Before this power failure the
output of the network is 0.92129 when input x was applied. Compute
the value of w12 weight supposing that the activation function is
the logsig
(Ans: w12 = 7.5)
2). A power failure damaged weights w11 and w12. Before the
damage the output network was 0.539915 when the first column of x
was applied and 0.327393 for the second column of x. Compute the
values of w11 and...
