Question 6: Varying the Hidden Layers Create a learning curve for testPenData where the number of hidden layer perceptrons is the independent variable and the average accuracy is the dependent variable.
Question 6: Varying the Hidden Layers For testPenData , discuss any notable trends you saw related to increasing the size of the hidden layers in your neural net. Answer: As the size of the hidden layers increase, the average accuracy increases and then plateaus. There is not a very clear trend, but the data generally increases and plateaus around 15 hidden layers.
Question 6: Varying the Hidden Layers Statistic table for testCarData report the max, average, and standard deviation at various amount of perceptrons. Number of Perceptrons at the Hidden Layer 0 5 10 15 20 25 30 35 40 Max Accuracy 0.6400 0.9800 0.9700 0.9550 0.9650 0.9700 0.9800 0.9800 0.9800 Avg Accuracy 0.6400 0.9690 0.9640 0.9530 0.9590 0.9610 0.9670 0.9680 0.9610 Standard Deviation 0.0000 0.0086 0.0037 0.0024 0.0037 0.0066 0.0108 0.0081 0.0128

Question 6: Varying the Hidden Layers Create a learning curve for testCarData where the number of hidden layer perceptrons is the independent variable and the average accuracy is the dependent variable.
Question 6: Varying the Hidden Layers For testCarData , discuss any notable trends you saw related to increasing the size of the hidden layers in your neural net. Answer: As the size of the hidden layers increase, the average accuracy increases sharply and then levels out. The learning curve is not consistent and does not showcase a specific relationship with the number of hidden layers.
Question 7 (extra credit): Learning XOR Report the max accuracy, average accuracy, and standard deviation of the neural net that you have trained with 1) no hidden layer, and 2) a hidden layer with various amount of perceptrons (at least 3 different amounts) No Hidden Layer Hidden Layer ___ perceptrons ___ perceptrons ___ perceptrons Max Accuracy Avg Accuracy Standard Deviation
