CallbackAsyncTuning {mlr3tuning}

Create Asynchronous Tuning Callback

Description

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().
