Intro to Statistical Learning (2nd Ed), Solution to Problem 10.1c

10.1C: Consider a neural network with two hidden layers: p=4 input units, 2 units in the first hidden layer, 3 units in the second hidden layer, and a single output. (a) Draw a picture of the network, similar to Figures 10.1 or 10.4. (b) Write out an expression for f(X) , assuming ReLU activation functions. Be as explicit as you can! (c) Now plug in some values for the coefficients and write out the value of f(X) . (d) How many parameters are there?
