MirrorSymmetry

class baybe.symmetries.MirrorSymmetry[source]

Bases: Symmetry

Class for representing mirror symmetries.

A mirror symmetry expresses that certain parameters can be inflected at a mirror point without affecting the outcome of the model. For instance, this is the case if $f(x,y) = f(-x,y)$ (mirror point is 0).

Public attributes and properties

mirror_point

The mirror point.

parameter_names

The names of the parameters affected by the symmetry.

use_data_augmentation

Flag indicating whether data augmentation would be used with surrogates that support this.

__init__(parameter_name: str, *, use_data_augmentation: bool = True, mirror_point=0.0)

Method generated by attrs for class MirrorSymmetry.

For details on the parameters, see Public attributes and properties.

augment_measurements(df: pd.DataFrame, _: Iterable[Parameter])[source]

Augment the given measurements according to the symmetry.

Parameters:
  • df (pd.DataFrame) – The dataframe containing the measurements to be augmented.

  • parameters – Parameter objects carrying additional information (might not be needed by all augmentation implementations).

Return type:

pd.DataFrame

Returns:

The augmented dataframe including the original measurements.

classmethod from_dict(dictionary: dict)

Create an object from its dictionary representation.

Parameters:

dictionary (dict) – The dictionary representation.

Return type:

TypeVar(_T, bound= SerialMixin)

Returns:

The reconstructed object.

classmethod from_json(source: str | Path | SupportsRead[str], /)

Create an object from its JSON representation.

Parameters:

source (str | Path | SupportsRead[str]) –

The JSON source. Can be:

  • A string containing JSON content.

  • A file path or Path object pointing to a JSON file.

  • A file-like object with a read() method.

Raises:

ValueError – If source is not one of the allowed types.

Return type:

_T

Returns:

The reconstructed object.

summary()

Return a custom summarization of the symmetry.

Return type:

dict

to_dict()

Create an object’s dictionary representation.

Return type:

dict

Returns:

The dictionary representation of the object.

to_json(sink: str | Path | SupportsWrite[str] | None = None, /, *, overwrite: bool = False, **kwargs: Any)

Create an object’s JSON representation.

Parameters:
  • sink (str | Path | SupportsWrite[str] | None) –

    The JSON sink. Can be:

    • None (only returns the JSON string).

    • A file path or Path object pointing to a location where to write the JSON content.

    • A file-like object with a write() method.

  • overwrite (bool) – Boolean flag indicating if to overwrite the file if it already exists. Only relevant if sink is a file path or Path object.

  • **kwargs (Any) – Additional keyword arguments to pass to json.dumps().

Raises:

FileExistsError – If sink points to an already existing file but overwrite is False.

Return type:

str

Returns:

The JSON representation as a string.

validate_searchspace_context(searchspace: SearchSpace)[source]

See base class.

Parameters:

searchspace (SearchSpace) – The searchspace to validate against.

Raises:

TypeError – If the affected parameter is not numerical.

Return type:

None

mirror_point: float

The mirror point.

property parameter_names: tuple[str]

The names of the parameters affected by the symmetry.

use_data_augmentation: bool

Flag indicating whether data augmentation would be used with surrogates that support this.
