mlr_measures_surv.mae: Mean Absolute Error Survival Measure

In mlr3proba: Probabilistic Supervised Learning for 'mlr3'

Mean Absolute Error Survival Measure

Description

Calculates the mean absolute error (MAE).

The MAE is defined by

1/n ∑ |t - t*|

where t is the true value and t* is the prediction.

Censored observations in the test set are ignored.

Dictionary

This Measure can be instantiated via the dictionary mlr_measures or with the associated sugar function msr():

mlr_measures$get("surv.mae")
msr("surv.mae")
