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.

Installation

Add this line to your application's Gemfile:

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)
