syne_tune.optimizer.schedulers.searchers.gp_searcher_factory module

syne_tune.optimizer.schedulers.searchers.gp_searcher_factory.gp_fifo_searcher_factory(**kwargs)

Returns kwargs for _create_internal(), based on kwargs equal to search_options passed to and extended by scheduler (see FIFOScheduler).

Extensions of kwargs by the scheduler:

• scheduler: Name of scheduler ("fifo", "hyperband_*")

• config_space: Configuration space

Only Hyperband schedulers:

• resource_attr: Name of resource (or time) attribute

• max_epochs: Maximum resource value

Parameters:

kwargs – search_options coming from scheduler

Return type:

Dict[str, Any]

Returns:

kwargs for _create_internal()

syne_tune.optimizer.schedulers.searchers.gp_searcher_factory.gp_multifidelity_searcher_factory(**kwargs)

Returns kwargs for _create_internal(), based on kwargs equal to search_options passed to and extended by scheduler (see HyperbandScheduler).

Parameters:

kwargs – search_options coming from scheduler

Return type:

Dict[str, Any]

Returns:

kwargs for _create_internal()

syne_tune.optimizer.schedulers.searchers.gp_searcher_factory.constrained_gp_fifo_searcher_factory(**kwargs)

Returns kwargs for _create_internal(), based on kwargs equal to search_options passed to and extended by scheduler (see FIFOScheduler).

Parameters:

kwargs – search_options coming from scheduler

Return type:

Dict[str, Any]

Returns:

kwargs for _create_internal()

syne_tune.optimizer.schedulers.searchers.gp_searcher_factory.cost_aware_coarse_gp_fifo_searcher_factory(**kwargs)

Returns kwargs for _create_internal(), based on kwargs equal to search_options passed to and extended by scheduler (see FIFOScheduler).

This is for the coarse-grained variant, where costs \(c(x)\) are obtained together with metric values and are given a GP surrogate model.

Parameters:

kwargs – search_options coming from scheduler

Return type:

Dict[str, Any]

Returns:

kwargs for _create_internal()

syne_tune.optimizer.schedulers.searchers.gp_searcher_factory.cost_aware_fine_gp_fifo_searcher_factory(**kwargs)

Returns kwargs for _create_internal(), based on kwargs equal to search_options passed to and extended by scheduler (see FIFOScheduler).

This is for the fine-grained variant, where costs \(c(x, r)\) are obtained with each report and are represented by a CostModel surrogate model.

Parameters:

kwargs – search_options coming from scheduler

Return type:

Dict[str, Any]

Returns:

kwargs for _create_internal()

syne_tune.optimizer.schedulers.searchers.gp_searcher_factory.cost_aware_gp_multifidelity_searcher_factory(**kwargs)

Parameters:

kwargs – search_options coming from scheduler

Return type:

Dict[str, Any]

Returns:

kwargs for _create_internal()

syne_tune.optimizer.schedulers.searchers.gp_searcher_factory.hypertune_searcher_factory(**kwargs)

Returns kwargs for _create_internal(), based on kwargs equal to search_options passed to and extended by scheduler (see HyperbandScheduler).

Parameters:

Return type:

Dict[str, Any]

Returns:

kwargs for _create_internal()
