Instructions: Choose either the Red or Blue class and then click on the canvas to add points for the chosen class. You can change the architecture of the nework by adding/removing numbers from the 'Hidden' textbox. Each number is the number of neurons in that hidden layer. It begins with '4 4' which means you have 4 neurons in the first hidden layer and 4 neurons in the second hidden layer. If you delete the hidden layers you are left with a linear classifier.
