Using the tiny neural network model presented on chapter 10 PPT slide 20 , shown below, write the activation function for each hidden node (3, 4, \& 5). For a new record: Fat =0.4 and Salt =0.5, show the calculation for node 6 and 7 (from input layer, to hidden layer, to output layer). Use 4 decimal digits in calculation and results. What is the classification of this new re record
