# Example

Want to setup a simple network using Juggernaut? 

This sample creates a random binary operation network with one hidden layer:

```rust
fn main() {
    let dataset = vec![
        Sample::new(vec![0f64, 0f64, 1f64], vec![0f64]),
        Sample::new(vec![0f64, 1f64, 1f64], vec![0f64]),
        Sample::new(vec![1f64, 0f64, 1f64], vec![1f64]),
        Sample::new(vec![1f64, 1f64, 1f64], vec![1f64])
    ];
    
    let mut test = NeuralNetwork::new();

    let sig_activation = Sigmoid::new();

    // 1st layer = 2 neurons - 3 inputs
    test.add_layer(NeuralLayer::new(2, 3, sig_activation));

    // 2nd layer = 1 neuron - 2 inputs
    test.add_layer(NeuralLayer::new(1, 2, sig_activation));

    test.error(|err| {
        println!("error({})", err.to_string());
    });

    test.train(dataset, 1000, 0.1f64);
    
    let think = test.evaluate(Sample::predict(vec![1f64, 0f64, 1f64]));

    println!("Evaluate [1, 0, 1] = {:?}", think.get(0, 0));

}

```

and the output of `think` is the prediction of the network after training.
