| mlr_measures_dens.logloss {mlr3proba} | R Documentation |
Calculates the cross-entropy, or logarithmic (log), loss.
The logloss, in the context of probabilistic predictions, is defined as the negative log probability density function, f, evaluated at the observed value, y,
L(f, y) = -log(f(y))
Type: "density"
Range: [0, Inf)
Minimize: TRUE
Required prediction: pdf
