A Learner
that encapsulates a Graph
to be used in
mlr3 resampling and benchmarks.
The Graph must return a single Prediction
on its $predict()
call. The result of the $train()
call is discarded, only the
internal state changes during training are used.
The predict_type
of a GraphLearner
can be obtained or set via it's predict_type
active binding.
Setting a new predict type will try to set the predict_type
in all relevant
PipeOp
/ Learner
encapsulated within the Graph
.
Similarly, the predict_type of a Graph will always be the smallest denominator in the Graph
.
