Specifies ranges of integer, continuous, and categorical hyperparameters that a hyperparameter tuning job searches. The hyperparameter tuning job launches training jobs with hyperparameter values within these ranges to find the combination of values that result in the training job with the best performance as measured by the objective metric of the hyperparameter tuning job.

Note
You can specify a maximum of 20 hyperparameters that a hyperparameter tuning job can search over. Every possible value of a categorical parameter range counts against this limit.

CategoricalParameterRanges The array of CategoricalParameterRange objects that specify ranges of categorical hyperparameters that a hyperparameter tuning job searches.
Type: Array of CategoricalParameterRange objects
Array Members: Minimum number of 0 items. Maximum number of 20 items.
Required: No

ContinuousParameterRanges The array of ContinuousParameterRange objects that specify ranges of continuous hyperparameters that a hyperparameter tuning job searches.
Type: Array of ContinuousParameterRange objects
Array Members: Minimum number of 0 items. Maximum number of 20 items.
Required: No

IntegerParameterRanges The array of IntegerParameterRange objects that specify ranges of integer hyperparameters that a hyperparameter tuning job searches.
Type: Array of IntegerParameterRange objects
Array Members: Minimum number of 0 items. Maximum number of 20 items.
Required: No
