F_beta {hypergate} | R Documentation |
F_beta
Description
Compute a F_beta score comparing two boolean vectors
Usage
F_beta(pred, truth, beta = 1)
Arguments
pred |
boolean vector of predicted values |
truth |
boolean vector of true values |
beta |
Weighting of yield as compared to precision. Increase beta so that the optimization favors yield, or decrease to favor purity. |
Examples
data(Samusik_01_subset)
truth=c(rep(TRUE,40),rep(FALSE,60))
pred=rep(c(TRUE,FALSE),50)
table(pred,truth) ##40% purity, 50% yield
#' F_beta(pred=pred,truth=truth,beta=2) ##Closer to yield
F_beta(pred=pred,truth=truth,beta=1.5) ##Closer to yield
F_beta(pred=pred,truth=truth,beta=1) ##Harmonic mean
F_beta(pred=pred,truth=truth,beta=0.75) ##Closer to purity
F_beta(pred=pred,truth=truth,beta=0.5) ##Closer to purity
