Specialized bbotk::CallbackAsync for asynchronous tuning.
Callbacks allow to customize the behavior of processes in mlr3tuning.
The callback_async_tuning()
function creates a CallbackAsyncTuning.
Predefined callbacks are stored in the dictionary mlr_callbacks and can be retrieved with clbk()
.
For more information on tuning callbacks see callback_async_tuning()
.
