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.
Note the predict_type
of a GraphLearner
does currently not track the predict_type
of any Learner
encapsulated within the Graph
. Therefore, when requesting
e.g. "prob"
predictions, the predict_type
of both the encapsulated Learner
and the wrapping GraphLearner
need to be set to "prob"
.
