Composer

class fedot.core.composer.composer.Composer(optimizer, composer_requirements=None)

Bases: ABC

Base class used for receiving composite operations via optimization

Parameters

• optimizer (GraphOptimizer) – optimizer generated in ComposerBuilder

• composer_requirements (Optional[OptimizationParameters]) – requirements for composition process

abstract compose_pipeline(data)

Run composition process for optimal pipeline structure search

Parameters

data (Union[InputData, MultiModalData]) – Data used for problem solving

Returns

For single-objective optimization -> the best pipeline.

For multi-objective optimization -> a list of the best pipelines is returned.

Return type

Union[Pipeline, List[Pipeline]]

Notes

Returned pipelines are ordered by the descending primary metric (the first is the best).
