__init__(beta=0.2)

Method generated by attrs for class qUpperConfidenceBound.

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

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.

to_botorch(surrogate: Surrogate, searchspace: SearchSpace, train_x: DataFrame, train_y: DataFrame)

Create the botorch-ready representation of the function.

to_dict()

Create an object’s dictionary representation.

Return type:

dict

to_json()

Create an object’s JSON representation.

Return type:

str

Returns:

The JSON representation as a string.

abbreviation: ClassVar[str] = 'qUCB'

An alternative name for type resolution.

beta: float

Trade-off parameter for mean and variance.

A value of zero makes the acquisition mechanism consider the posterior predictive mean only, resulting in pure exploitation. Higher values shift the focus more and more toward exploration.
