Unidom Stapar 统计模式识别模型引擎

Unidom (UNIfied Domain Object Model) is a series of domain model engines. The StAPaR (Statistical Approach of Pattern Recognition) domain model engine includes Classifier, Sample, Feature, Pattern Library, Pattern Library Inclusion, and Pattern Matching models. Unidom (统一领域对象模型)是一系列的领域模型引擎。统计模式识别领域模型引擎包括采样和匹配的模型。

Usage in Gemfile

gem 'unidom-stapar'

Run the Database Migration

rake db:migrate

The migration versions start with 200601.

Call the Model

Classifier

matched = nil
similarity_percentage = 0
valve = 60
candidates.each do |candidate|
  similarity = recognize input, candidate
  if similarity > valve
    if similarity > similarity_percentage
      matched = candidate
      similarity_percentage = similarity
    end
  end
end

if matched.present?
  PatternMatching.match!(input, matched: matched, with: similarity_percentage, above: valve, at: Time.now)
else
  false
end

Include the Concerns

include Unidom::Stapar::Concerns::AsSample
include Unidom::Stapar::Concerns::AsFeature

As Feature

The As Feature concern do the following tasks for the includer automatically:

1. Define the belongs_to :classifier macro as: belongs_to :classifier, class_name: 'Unidom::Stapar::Classifier'
2. Define the belongs_to :sample macro as: belongs_to :sample, polymorphic: true

Disable the Model & Migration

If you only need the app components other than models, the migrations should be neglected, and the models should not be loaded.

# config/initializers/unidom.rb
Unidom::Common.configure do |options|

  options[:neglected_namespaces] = %w{
    Unidom::Stapar
  }

end
