ContextAsyncTuning | R Documentation |
A CallbackAsyncTuning accesses and modifies data during the optimization via the ContextAsyncTuning
.
See the section on active bindings for a list of modifiable objects.
See callback_async_tuning()
for a list of stages that access ContextAsyncTuning
.
Changes to $instance
and $optimizer
in the stages executed on the workers are not reflected in the main process.

-> ContextAsyncTuning
xs_learner
(list())
The hyperparameter configuration currently evaluated.
Contains the values on the learner scale i.e. transformations are applied.
resample_result
(mlr3::BenchmarkResult)
The resample result of the hyperparameter configuration currently evaluated.
aggregated_performance
(list()
)
Aggregated performance scores and training time of the evaluated hyperparameter configuration.
This list is passed to the archive.
A callback can add additional elements which are also written to the archive.
result_learner_param_vals
(list())
The learner parameter values passed to instance$assign_result()
.
