Automated Pipeline search.

Methods

__init__

Automated pipeline search

add_to_rankings

Fits and evaluates a given pipeline then adds the results to the automl rankings with the requirement that automl search has been run.

describe_pipeline

Describe a pipeline

get_pipeline

Given the ID of a pipeline training result, returns an untrained instance of the specified pipeline initialized with the parameters used to train that pipeline during automl search.

load

Loads AutoML object at file path

save

Saves AutoML object at file path

score_pipelines

Score a list of pipelines on the given holdout data.

search

Find the best pipeline for the data set.

train_pipelines

Train a list of pipelines on the training data.

Attributes

best_pipeline

Returns a trained instance of the best pipeline and parameters found during automl search.

full_rankings

Returns a pandas.DataFrame with scoring results from all pipelines searched

rankings

Returns a pandas.DataFrame with scoring results from the highest-scoring set of parameters used with each pipeline.

results

Class that allows access to a copy of the results from automl_search.
