Method Detail

getPrecision

public Double getPrecision()

Gets the precision.

A metric that measures how many of the overall documents are classified correctly.

Returns:

the precision

getRecall

public Double getRecall()

Gets the recall.

A metric that measures how often documents that should be classified into certain classes are classified into those classes.

Returns:

the recall

getF1

public Double getF1()

Gets the f1.

A metric that measures whether the optimal balance between precision and recall is reached. The F1 score can be interpreted as a weighted average of the precision and recall values. An F1 score reaches its best value at 1 and worst value at 0.

Returns:

the f1
