Instances
newClassifierEvaluationMetrics :: ClassifierEvaluationMetrics Source #
Create a value of ClassifierEvaluationMetrics
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:microPrecision:ClassifierEvaluationMetrics'
, classifierEvaluationMetrics_microPrecision
- 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. Unlike the Precision metric which
comes from averaging the precision of all available labels, this is
based on the overall score of all precision scores added together.
$sel:microF1Score:ClassifierEvaluationMetrics'
, classifierEvaluationMetrics_microF1Score
- 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.
$sel:recall:ClassifierEvaluationMetrics'
, classifierEvaluationMetrics_recall
- A measure of how complete the classifier results are for the test data.
High recall means that the classifier returned most of the relevant
results.
$sel:precision:ClassifierEvaluationMetrics'
, classifierEvaluationMetrics_precision
- A measure of the usefulness of the classifier results in the test data.
High precision means that the classifier returned substantially more
relevant results than irrelevant ones.
$sel:microRecall:ClassifierEvaluationMetrics'
, classifierEvaluationMetrics_microRecall
- A measure of how complete the classifier results are for the test data.
High recall means that the classifier returned most of the relevant
results. Specifically, this indicates how many of the correct categories
in the text that the model can predict. It is a percentage of correct
categories in the text that can found. Instead of averaging the recall
scores of all labels (as with Recall), micro Recall is based on the
overall score of all recall scores added together.
$sel:f1Score:ClassifierEvaluationMetrics'
, classifierEvaluationMetrics_f1Score
- A measure of how accurate the classifier 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.
$sel:hammingLoss:ClassifierEvaluationMetrics'
, classifierEvaluationMetrics_hammingLoss
- Indicates the fraction of labels that are incorrectly predicted. Also
seen as the fraction of wrong labels compared to the total number of
labels. Scores closer to zero are better.
$sel:accuracy:ClassifierEvaluationMetrics'
, classifierEvaluationMetrics_accuracy
- The fraction of the labels that were correct recognized. It is computed
by dividing the number of labels in the test documents that were
correctly recognized by the total number of labels in the test
documents.
