next steps, make the tools available in auto-ml

  • create a parameter to say that the classification is ordinal (not sure we can that)
  • add 'composition' step that make the transformation of the underlying model
  • add condition : regressor model should be drawn if 'ClassifierFromRegressor'
  • add condition : classifier that allow multi-output be drawn if 'ClassifierORdinal'
