The "hello world" of neural networks: a simple 3-layer feed-forward | |
network that implements an XOR logic gate. | |
The first layer is the input layer. It has two neurons a and b, which | |
are the two inputs to the XOR gate. | |
The middle layer is the hidden layer. This has two neurons h1, h2 that | |
will learn what it means to be an XOR gate. | |
