Neural network implemented in Java to recognize digits for academic purposes. The implemented artificial neural network achieved an error rate of 3.4% on the MNIST dataset.
#MNIST database Link to MNIST dataset: http://yann.lecun.com/exdb/mnist. The files should be placed in the same directory.
#Code example XOR Here is an example on the XOR problem.

public static void main(String[] args) {
//Creating a new feed-forward neural network with 3 layers
Network n = new Network(new int[] {2,2,1});
//Add training data
n.addTrainingData(new double[] {0,0}, new double[] {0});
n.addTrainingData(new double[] {1,0}, new double[] {1});
n.addTrainingData(new double[] {0,1}, new double[] {1});
n.addTrainingData(new double[] {1,1}, new double[] {0});
//Train network for 500 epoches, 0.3 learning rate
n.train(500,0.3);
