We've expanded our simple example from the Chapter 2, What is a Neural Network and How Do I Train One? quite a bit. At this point, it would be a good idea to have a little fun. Try the following and observe for yourself what happens, in order to get a better understanding of the impact your choices may have. For example, you should try all of the following:

• Change the loss function
• Change the number of units in each layer
• Change the number of layers
• Change the number of epochs
• Change the batch size
