Properties

f1Score → double?

A measure of how accurate the recognizer results are for the test data. It is derived from the Precision and Recall values. The F1Score is the harmonic average of the two scores. The highest score is 1, and the worst score is 0.

final

hashCode → int

precision → double?

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.

final

recall → double?

A measure of how complete the recognizer results are for the test data. High recall means that the recognizer returned most of the relevant results.
