RandomRecommender¶

class baybe.recommenders.pure.nonpredictive.sampling.RandomRecommender[source]¶

Recommends experiments randomly.

Public methods

`__init__`(*[, ...])	Method generated by attrs for class NonPredictiveRecommender.
`recommend`(batch_size, searchspace[, ...])	Recommend a batch of points from the given search space.

Public attributes and properties

`allow_recommending_already_measured`	Allow to make recommendations that were measured previously.
`allow_repeated_recommendations`	Allow to make recommendations that were already recommended earlier.
`compatibility`	Class variable reflecting the search space compatibility.

__init__(*, allow_repeated_recommendations: bool = False, allow_recommending_already_measured: bool = True)¶

Method generated by attrs for class NonPredictiveRecommender.

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

recommend(batch_size: int, searchspace: SearchSpace, objective: Objective | None = None, measurements: DataFrame | None = None)¶

Recommend a batch of points from the given search space.

Parameters:

batch_size (int) – The number of points to be recommended.
searchspace (SearchSpace) – The search space from which to recommend the points.
objective (Optional[Objective]) – An optional objective to be optimized.
measurements (Optional[DataFrame]) – Optional experimentation data that can be used for model training. The data is to be provided in “experimental representation”: It needs to contain one column for each parameter spanning the search space (column name matching the parameter name) and one column for each target tracked by the objective (column name matching the target name). Each row corresponds to one conducted experiment, where the parameter columns define the experimental setting and the target columns report the measured outcomes.

Return type:

DataFrame

Returns:

A dataframe containing the recommendations in experimental representation as individual rows.

allow_recommending_already_measured: bool¶: Allow to make recommendations that were measured previously. This only has an influence in discrete search spaces.

allow_repeated_recommendations: bool¶: Allow to make recommendations that were already recommended earlier. This only has an influence in discrete search spaces.

compatibility: ClassVar[SearchSpaceType] = 'HYBRID'¶: Class variable reflecting the search space compatibility.
