Mnist

Utility ruby gem for easily loading and parsing the MNIST Database of handwritten digits for machine learning purposes.

Based on work by kenta murata.

Add this line to your application's Gemfile:

gem 'mnist-learn'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mnist-learn

Load test and training data easily.

require 'mnist-learn'

minst = Mnist.read_data_sets('data', one_hot: false) # auto download test and training archives and store them in /data
images = minst.train.images
labels = minst.train.labels

#you can also iterate in batches

train_images, train_labels = minst.train.next_batch(100)
test_images, test_labels = minst.test.next_batch(100)

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.
