Implementing Neural Networks in Javascript

The MNIST database containing 60,000 examples for training and 10,000 examples for testing can be downloaded from LeCun's website. Instead of downloading the database and converting the data to actual images, we can use the helpful library MNIST digits, which creates test- and training sets automatically. If you're using the MNIST digits library, this is checked automatically. To improve the results, the number of elements in the training set and the iterations for the training should be increased.
