Application VectorRegression

Cédric Traizet requested to merge app_vector_regression into develop


This merge request adds a new application VectorRegression that performs regression on input vector data according to a regression model.

This application is almost the same as VectorClassifier. The differences are:

  • The label types are different in classification and regression (unsigned int vs float), as well as the ogr field type (OFTInteger versus OFTFloat)
  • we need to call SetRegressionMode(1) on the model created by the MachineLearningModelFactory

Instead of creating the VectorRegression by copy-pasting almost all the VectorClassifier application, I tried to factorize the code in VectorClassifier using templates.

  • I created a new application VectorPrediction<bool RegressionMode> that performs regression when RegressionMode =1 and classification when RegressionMode = 0. The code of this application is the code of the old VectorClassifier, whith some modification to use the right types depending on RegressionMode.
  • VectorClassifier is defined VectorPrediction<0> and VectorRegression as VectorPrediction<1>.
  • The DoInit method is defined differently for VectorClassifier and VectorRegression using template specialization, to generate different documentations for the two applications
