• python >= 2.6
• numpy
• matplotlib

Usage

python main.py mnist_path valid_count test_count train_count network_width

• mnist_path: the cpickled mnist database
• valid_count: the size of the validation dataset (<= 10000)
• test_count: the size of the testing dataset (<= 10000)
• train_count: the size of the training dataset (<= 60000)
• network_width: the size of the neural network (between 4 and 30 is good)

For example:

python main.py data/mnist.pkl.gz 100 100 600 10

is a good starting point
