An example digit (labeled as a 2) from the MNIST dataset. I was pretty surprised that with the current release of scikit-learn (0.17 at the time of writing), a c3.8xlarge EC2 instance , and about 1.5 hours of processing time, I could obtain above 98% accuracy on the test data (and win the competition).
The MNIST database, an extension of the NIST database, is a low-complexity data collection of handwritten digits used to train and test various supervised machine learning algorithms. The database contains 70,000 28x28 black and white images representing the digits zero through nine. The data is split into two subsets, with 60,000 images belonging to the training set and 10,000 ... An example digit (labeled as a 2) from the MNIST dataset.
