score = c("mae", "mse", "rec", "rroc"),
new_score = NULL
)
object |
An object of class |
score |
Vector of score names to be calculated. Possible values: |
new_score |
A named list of functions that take one argument: object of class 'explainer' and return a numeric value. The measure calculated by the function should have the property that lower score value indicates better model. |
data |
New data that will be used to calculate scores. Pass |
... |
Other arguments dependent on the score list. |
