]`. Omitting other members, this is exactly how our neural network is defined:

Additionally, each node within the network is defined by its activation function. This function defines what a node outputs to the next layer given the sum of the inputs it received from the previous layer. It applies to all layers except the input layer whose value is set by the input vector. In our implementation we use the following code for our n
