Swift Neural Network

Simple Swift implementation of Neural Network. Any size of network can be created.

Usage

Creates small neural network with four input nodes and two output nodes and two hidden layers with 7 and 5 nodes:

let nn = NeuralNetwork(layers: [4, 7, 5, 2], bias: 0.75, eta: 0.5)

Teaches network with input and expected output

nn.teach(input: data.input, expectedOutput: data.output)

Evaluates some input

nn.eval(input: [0.8, 0.75, 0.1, 0.01])

To do

• make it work on multiple threads and cores
