EvaluationMeasures.F1Score: EvaluationMeasures.F1Score

Description

F1Score of prediction

Usage

EvaluationMeasures.F1Score(Real = NULL, Predicted = NULL, Positive = 1, TP = NULL, TN = NULL, FP = NULL, FN = NULL)

Arguments

Real

Real binary values of the class

Predicted

Predicted binary values of the class

Positive

Consider 1 label as Positive Class unless changing this parameter to 0

TP

Number of True Positives. Number of 1 in real which is 1 in predicted.

TN

Number of True Negatives. Number of 0 in real which is 0 in predicted.

FP

Number of False Positives. Number of 0 in real which is 1 in predicted.

FN

Number of False Negatives. Number of 1 in real which is 0 in predicted.

Value

F1Score

Details

F1Score is Harmonic mean of precision and recall.

By getting the predicted and real values or number of TP,TN,FP,FN return the F1Score or F1Measure of model

Examples

EvaluationMeasures.F1Score(c(1,0,1,0,1,0,1,0),c(1,1,1,1,1,1,0,0))
