--
-- Starts a hyperparameter tuning job. A hyperparameter tuning job finds
-- the best version of a model by running many training jobs on your
-- dataset using the algorithm you choose and values for hyperparameters
-- within ranges that you specify. It then chooses the hyperparameter
-- values that result in a model that performs the best, as measured by an
-- objective metric that you choose.
--
-- A hyperparameter tuning job automatically creates Amazon SageMaker
-- experiments, trials, and trial components for each training job that it
-- runs. You can view these entities in Amazon SageMaker Studio. For more
-- information, see
-- <https://docs.aws.amazon.com/sagemaker/latest/dg/experiments-view-compare.html#experiments-view View Experiments, Trials, and Trial Components>.
--
-- Do not include any security-sensitive information including account
-- access IDs, secrets or tokens in any hyperparameter field. If the use of
-- security-sensitive credentials are detected, SageMaker will reject your
-- training job request and return an exception error.
