Inverts target-transformations done during training based on a supplied inversion
function. Typically should be used in combination with a subclass of PipeOpTargetTrafo.
During prediction phase the function supplied through "fun" is called with a list containing
the "prediction" as a single element, and should return a list with a single element
(a Prediction) that is returned by PipeOpTargetInvert.
Construction
id::character(1)
Identifier of resulting object, default"targetinvert".param_vals:: namedlist
List of hyperparameter settings, overwriting the hyperparameter settings that would otherwise be set during construction. Defaultlist().
Input and Output Channels
PipeOpTargetInvert has two input channels named "fun" and "prediction". During
training, both take NULL as input. During prediction, "fun" takes a function and
"prediction" takes a Prediction.
PipeOpTargetInvert has one output channel named "output" and returns NULL during
training and a Prediction during prediction.
State
The $state is left empty (list()).
