The Loss Function In order for our neural net to “learn” we first need some measure of how it is doing. This is called the loss function. It measures how far off the output of our net is from what we expect it to be. There are many kinds of loss function but they all…

In this post we will begin implementing our neural net. We will start by implementing the basic data structures that comprise our neural net. Then I explain what exactly happens during the forward pass, followed by the code. The Neural Net Class First thing’s first we need a neural net: Each layer in our net…
