ruby-dnn
ruby-dnn is a ruby deep learning library. This library supports full connected neural network and convolution neural network and recurrent neural network. Currently, you can get 99% accuracy with MNIST and 82% with CIFAR 10.
Installation
Add this line to your application's Gemfile:
gem 'ruby-dnn'
And then execute:
$ bundle
Or install it yourself as:
$ gem install ruby-dnn
Usage
MNIST MLP example
model = Sequential.new
model << InputLayer.new(784)
model << Dense.new(256)
model << ReLU.new
model << Dense.new(256)
model << ReLU.new
model << Dense.new(10)
model.setup(Adam.new, SoftmaxCrossEntropy.new)
model.train(x_train, y_train, 10, batch_size: 128, test: [x_test, y_test])
accuracy, loss = model.evaluate(x_test, y_test)
puts "accuracy: #{accuracy}"
puts "loss: #{loss}"
When create a model with 'define by run' style:
class MLP < Model
def initialize
super
@d1 = Dense.new(256)
@d2 = Dense.new(256)
@d3 = Dense.new(10)
end
def forward(x)
x = InputLayer.new(784).(x)
x = @d1.(x)
x = ReLU.(x)
x = @d2.(x)
x = ReLU.(x)
x = @d3.(x)
x
end
end
model = MLP.new
model.setup(Adam.new, SoftmaxCrossEntropy.new)
model.train(x_train, y_train, 10, batch_size: 128, test: [x_test, y_test])
accuracy, loss = model.evaluate(x_test, y_test)
puts "accuracy: #{accuracy}"
puts "loss: #{loss}"

Datasets
By setting the environment variable RUBY_DNN_DOWNLOADS_PATH
, you can specify the path to read dataset.
- Iris
- MNIST
- Fashion-MNIST
- CIFAR-10
- CIFAR-100
- STL-10
Use GPU
If you do require "cumo/narray"
before require "dnn"
, you can run it on GPU.
Or, set the environment variable RUBY_DNN_USE_CUMO
to ENABLE
to force the GPU to be used.
TODO
- Write a test.
- Write a document.
- Improve performance when using GPU.
Development
After checking out the repo, run bin/setup
to install dependencies. Then, run rake "test"
to run the tests. You can also run bin/console
for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install
. To release a new version, update the version number in version.rb
, and then run bundle exec rake release
, which will create a git tag for the version, push git commits and tags, and push the .gem
file to rubygems.org.
