Unformatted text preview: (18 Points) Run back-propagation using these same parameter values for one iteration to determine new weight values for WAD , WBD , and WCD . Use your results from Part A and Part B, and assume a learning rate of r = 2 and a desired output, d=1. Part D: (8 Points) Hermione changes all the decision functions in the original network, before training, from using a sigmoid function to using a threshold function (which outputs 1 if the input is greater than 0, and outputs 0 otherwise). Using X, Y, and Z and the standard logical operators (AND, NOT, and OR), determine a logic expression for the neural net. Assume that the inputs are always 0 (meaning false) or 1 (meaning true). 23 Quiz 4, Problem 1: SVMs (50 points) Part A: F.R.O.S.T. and the Snowmen (25 Points) You have been hired by the Foundation for Research into Occult Snow Transformations (F.R.O.S.T.) to investigate a strange new phenomenon. It seems that certain snowmen can be turned into living, talking creatures when an old silk hat is placed on their heads. So far, F.R.O.S.T. researchers have determined that the factors that b...
