Interfaces

class smac.callback.Callback

Bases: object

Callback interface with several methods that are called at different stages of the optimization process.

on_ask_end(smbo, info)

Called after the intensifier is asked for the next trial.

Return type:

None

on_ask_start(smbo)

Called before the intensifier is asked for the next trial.

Return type:

None

on_end(smbo)

Called after the optimization finished.

Return type:

None

on_iteration_end(smbo)

Called after an iteration ended.

Return type:

None

on_iteration_start(smbo)

Called before the next run is sampled.

Return type:

None

on_next_configurations_end(config_selector, config)

Called after the intensification asks for new configurations. Essentially, this callback is called before the surrogate model is trained and before the acquisition function is called.

Return type:

None

on_next_configurations_start(config_selector)

Called before the intensification asks for new configurations. Essentially, this callback is called before the surrogate model is trained and before the acquisition function is called.

Return type:

None

on_start(smbo)

Called before the optimization starts.

Return type:

None

on_tell_end(smbo, info, value)

Called after the stats are updated and the trial is added to the runhistory. Optionally, returns false to gracefully stop the optimization.

Return type:

Optional[bool]

on_tell_start(smbo, info, value)

Called before the stats are updated and the trial is added to the runhistory. Optionally, returns false to gracefully stop the optimization.

Return type:

Optional[bool]
