#algorithms_config ⇒ Array<Types::AutoMLAlgorithmConfig>
Stores the configuration information for the selection of algorithms used to train the model candidates.

A URL to the Amazon S3 data source containing selected features from the input data source to run an Autopilot job.

Instance Attribute Details

#algorithms_config ⇒ `Array<Types::AutoMLAlgorithmConfig>`

Stores the configuration information for the selection of algorithms used to train the model candidates.

The list of available algorithms to choose from depends on the training mode set in AutoMLJobConfig.Mode .

AlgorithmsConfig should not be set in AUTO training mode.
When AlgorithmsConfig is provided, one AutoMLAlgorithms attribute must be set and one only.

If the list of algorithms provided as values for AutoMLAlgorithms is empty, AutoMLCandidateGenerationConfig uses the full set of algorithms for the given training mode.
When AlgorithmsConfig is not provided, AutoMLCandidateGenerationConfig uses the full set of algorithms for the given training mode.

For the list of all algorithms per training mode, see AutoMLAlgorithmConfig.

For more information on each algorithm, see the Algorithm support section in Autopilot developer guide.

Returns:

#feature_specification_s3_uri ⇒ `String`

A URL to the Amazon S3 data source containing selected features from the input data source to run an Autopilot job. You can input FeatureAttributeNames (optional) in JSON format as shown below:

\{ "FeatureAttributeNames":["col1", "col2", ...] \}.

You can also specify the data type of the feature (optional) in the format shown below:

\{ "FeatureDataTypes":\{"col1":"numeric", "col2":"categorical" ... \} \}

These column keys may not include the target column.

In ensembling mode, Autopilot only supports the following data types: numeric, categorical, text, and datetime. In HPO mode, Autopilot can support numeric, categorical, text, datetime, and sequence.

If only FeatureDataTypes is provided, the column keys (col1, col2,..) should be a subset of the column names in the input data.

If both FeatureDataTypes and FeatureAttributeNames are provided, then the column keys should be a subset of the column names provided in FeatureAttributeNames.

The key name FeatureAttributeNames is fixed. The values listed in ["col1", "col2", ...] are case sensitive and should be a list of strings containing unique values that are a subset of the column names in the input data. The list of columns provided must not include the target column.
