measure_accuracy: Performance measures used in classifier evaluation

Description

Classification accuracy on test set and other performance measure that can be used in CrossValidationSSL and LearningCurveSSL

Usage

measure_accuracy(trained_classifier, X_l = NULL, y_l = NULL, X_u = NULL,
  y_u = NULL, X_test = NULL, y_test = NULL)
measure_error(trained_classifier, X_l = NULL, y_l = NULL, X_u = NULL,
  y_u = NULL, X_test = NULL, y_test = NULL)
measure_losstest(trained_classifier, X_l = NULL, y_l = NULL, X_u = NULL,
  y_u = NULL, X_test = NULL, y_test = NULL)
measure_losslab(trained_classifier, X_l = NULL, y_l = NULL, X_u = NULL,
  y_u = NULL, X_test = NULL, y_test = NULL)
measure_losstrain(trained_classifier, X_l = NULL, y_l = NULL, X_u = NULL,
  y_u = NULL, X_test = NULL, y_test = NULL)

Arguments
