SubspaceContinuous

class baybe.searchspace.continuous.SubspaceContinuous

Bases: SerialMixin

Class for managing continuous subspaces.

Builds the subspace from parameter definitions, keeps track of search metadata, and provides access to candidate sets and different parameter views.

Method generated by attrs for class SubspaceContinuous.

classmethod empty()

Create an empty continuous subspace.

Return type:

SubspaceContinuous

classmethod from_bounds(bounds: DataFrame)

Create a hyperrectangle-shaped continuous subspace with given bounds.

Parameters:

bounds (DataFrame) – The bounds of the parameters.

Return type:

SubspaceContinuous

Returns:

The constructed subspace.

classmethod from_dataframe(df: DataFrame, parameters: Sequence[ContinuousParameter] | None = None)

Create a hyperrectangle-shaped continuous subspace from a dataframe.

More precisely, create the smallest axis-aligned hyperrectangle-shaped continuous subspace that contains the points specified in the given dataframe.

Parameters:

• df (DataFrame) – The dataframe specifying the points spanning the subspace.

• parameters (Optional[Sequence[ContinuousParameter]]) – Optional parameter objects corresponding to the columns in the given dataframe that can be provided to explicitly control parameter attributes. If a match between column name and parameter name is found, the corresponding parameter object is used. If a column has no match in the parameter list, a new baybe.parameters.numerical.NumericalContinuousParameter is created with default optional arguments. For more details, see baybe.parameters.utils.get_parameters_from_dataframe().

Raises:

ValueError – If parameter types other than baybe.parameters.numerical.NumericalContinuousParameter are provided.

Return type:

SubspaceContinuous

Returns:

The created continuous subspace.

classmethod from_dict(dictionary: dict)

Create an object from its dictionary representation.

Parameters:

dictionary (dict) – The dictionary representation.

Return type:

TypeVar(_T)

Returns:

The reconstructed object.

classmethod from_json(string: str)

Create an object from its JSON representation.

Parameters:

string (str) – The JSON representation of the object.

Return type:

TypeVar(_T)

Returns:

The reconstructed object.

classmethod from_parameter(parameter: ContinuousParameter)

Create a subspace from a single parameter.

Parameters:

parameter (ContinuousParameter) – The parameter to span the subspace.

Return type:

SubspaceContinuous

Returns:

The created subspace.
