  Type: DOUBLE
  Provider name: MicroF1Score
  Description: A measure of how accurate the classifier results are for the test data. It is a combination of the Micro Precision and Micro Recall values. The Micro F1Score is the harmonic mean of the two scores. The highest score is 1, and the worst score is 0.

  Type: DOUBLE
  Provider name: MicroPrecision
  Description: A measure of the usefulness of the recognizer results in the test data. High precision means that the recognizer returned substantially more relevant results than irrelevant ones.
