Max Absolute Error

Source: R/MeasureSimple.R
mlr_measures_regr.maxae.Rd

Measure to compare true observed response with predicted response in regression tasks.

Details

The Max Absolute Error is defined as $$ \max \left( \left| t_i - r_i \right| \right). $$

Note

The score function calls mlr3measures::maxae() from package mlr3measures.

If the measure is undefined for the input, NaN is returned. This can be customized by setting the field na_value.

msr("regr.maxae")
