Machine Learning in Ruby implemented Delta Learning method.
MLDelta is implemented by Ruby and Delta Learning Method in Machine Learning that is also a supervisor and used gradient method to find out the best solution.
require './ml_delta'
delta = MLDelta.new
delta.active_method = MLActiveMethod::TANH
delta.learning_rate = 0.8
delta.convergence_value = 0.001
delta.max_iteration = 1000
delta.add_patterns([1.0, -2.0, 0.0, -1.0], -1.0)
delta.add_patterns([0.0, 1.5, -0.5, -1.0], 1.0)
delta.setup_weights([1.0, -1.0, 0.0, 0.5])
# Setting the block of per iteration training
iteration_block = Proc.new do |iteration, weights|
puts "iteration : #{iteration}, weights : #{weights}"
end
# Setting the block of completion when it finish training
completion_block = Proc.new do |success, weights, total_iteration|
puts "success : #{success}, weights : #{weights}, total_iteration : #{total_iteration}"
# Verifying the pattern
delta.direct_output_by_patterns [1.0, -2.0, 0.0, -1.0] { |predication|
puts "predication result is #{predication}"
}
end
# Start in training
delta.training_with_iteration(iteration_block, completion_block)
1). If you wish automatic setups all weights of pattern that you could use delta.random_weights() to instead of delta.setup_weights().
# The random scopes of weights between (min, max)
delta.setup_random_scopes(-0.5, 0.5)
delta.random_weights()
2). If you just wanna see the result without iteration running that you could directly use the method as below :
delta.training_with_completion {
|success, weights, total_iteration|
puts "success : #{success}, weights : #{weights}, total_iteration : #{total_iteration}"
}
