TNn

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/t_nn. To experiment with that code, run bin/console for an interactive prompt.

TODO: Delete this and the text above, and describe your gem

Installation

Add this line to your application's Gemfile:

gem 't_nn'

And then execute:

$ bundle

Or install it yourself as:

$ gem install t_nn

Usage

simple feedforward_neural_network

respect for keras.

require "t_nn"

model = TNN::FeedForwardNeuralNetwork.new(learning_rate=0.1)

model.add_layer(node_num=2)
model.add_layer(node_num=3)
model.add_layer(node_num=1)

x_train = [[0.0, 0.0],[0.0, 1.0], [1.0, 0.0], [1.0, 1.0]]
y_train = [[ 0.0 ], [ 1.0 ],[ 1.0 ],[ 0.0 ]]
model.fit(x_train, y_train, epoch=50000)

x_test = x_train
y_test = y_train

err_rate = model.evaluate(x_test, y_test)

puts "err rate: #{err_rate}%"

# p x_test[0]
# model.propagation(x_text[0])
# puts model.get_output_layer[1].w

result

....

hop filed net

sample

require "t_nn"

data = [1.0, 1.0, -1.0, -1.0, 1.0]  # teacher data
hop_field_net = TNN::HopFieldNetwork.new(0.0, data)
hop_field_net.memorize
noisedData = TNN.add_noise_data(data, 0.0) # make test data
puts "======[before]======"
puts "#{TNN.evaluate(data, noisedData)}%"
hop_field_net.remember(noisedData)
puts "======[after]======"
puts "#{ TNN.evaluate(data,hop_field_net.nodes) }%" 

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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.
