  A channel is a named input source that training algorithms can consume. This channel is used for AutoML jobs V2 (jobs created by calling CreateAutoMLJobV2).
  - ChannelType (string) –
    
    The type of channel. Defines whether the data are used for training or validation. The default value is training. Channels for training and validation must share the same ContentType
    
    Note
    The type of channel defaults to training for the time-series forecasting problem type.
  - ContentType (string) –
    
    The content type of the data from the input source. The following are the allowed content types for different problems:
    - For tabular problem types: text/csv;header=present or x-application/vnd.amazon+parquet. The default value is text/csv;header=present.

        If you choose ManifestFile, S3Uri identifies an object that is a manifest file containing a list of object keys that you want SageMaker to use for model training. A ManifestFile should have the format shown below: [ {"prefix": "s3://DOC-EXAMPLE-BUCKET/DOC-EXAMPLE-FOLDER/DOC-EXAMPLE-PREFIX/"}, "DOC-EXAMPLE-RELATIVE-PATH/DOC-EXAMPLE-FOLDER/DATA-1", "DOC-EXAMPLE-RELATIVE-PATH/DOC-EXAMPLE-FOLDER/DATA-2", ... "DOC-EXAMPLE-RELATIVE-PATH/DOC-EXAMPLE-FOLDER/DATA-N" ]
        
        If you choose AugmentedManifestFile, S3Uri identifies an object that is an augmented manifest file in JSON lines format. This file contains the data you want to use for model training. AugmentedManifestFile is available for V2 API jobs only (for example, for jobs created by calling CreateAutoMLJobV2). Here is a minimal, single-record example of an AugmentedManifestFile: {"source-ref": "s3://DOC-EXAMPLE-BUCKET/DOC-EXAMPLE-FOLDER/cats/cat.jpg", "label-metadata": {"class-name": "cat" } For more information on AugmentedManifestFile, see Provide Dataset Metadata to Training Jobs with an Augmented Manifest File.

  - FeatureSpecificationS3Uri (string) –
    
    A URL to the Amazon S3 data source containing selected features from the input data source to run an Autopilot job V2. 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" ... } }
    
    Note
    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.
  - Mode (string) –
    
    The method that Autopilot uses to train the data. You can either specify the mode manually or let Autopilot choose for you based on the dataset size by selecting AUTO. In AUTO mode, Autopilot chooses ENSEMBLING for datasets smaller than 100 MB, and HYPERPARAMETER_TUNING for larger ones.
    
    The ENSEMBLING mode uses a multi-stack ensemble model to predict classification and regression tasks directly from your dataset. This machine learning mode combines several base models to produce an optimal predictive model. It then uses a stacking ensemble method to combine predictions from contributing members. A multi-stack ensemble model can provide better performance over a single model by combining the predictive capabilities of multiple models. See Autopilot algorithm support for a list of algorithms supported by ENSEMBLING mode.
    
    The HYPERPARAMETER_TUNING (HPO) mode uses the best hyperparameters to train the best version of a model. HPO automatically selects an algorithm for the type of problem you want to solve. Then HPO finds the best hyperparameters according to your objective metric. See Autopilot algorithm support for a list of algorithms supported by HYPERPARAMETER_TUNING mode.
  - GenerateCandidateDefinitionsOnly (boolean) –
    
    Generates possible candidates without training the models. A model candidate is a combination of data preprocessors, algorithms, and algorithm parameter settings.
  - ProblemType (string) –
    
    The type of supervised learning problem available for the model candidates of the AutoML job V2. For more information, see Amazon SageMaker Autopilot problem types.
    
    Note
    You must either specify the type of supervised learning problem in ProblemType and provide the AutoMLJobObjective metric, or none at all.
  - TargetAttributeName (string) – [REQUIRED]
    
    The name of the target variable in supervised learning, usually represented by ‘y’.
  - SampleWeightAttributeName (string) –
    
    If specified, this column name indicates which column of the dataset should be treated as sample weights for use by the objective metric during the training, evaluation, and the selection of the best model. This column is not considered as a predictive feature. For more information on Autopilot metrics, see Metrics and validation.
    
    Sample weights should be numeric, non-negative, with larger values indicating which rows are more important than others. Data points that have invalid or no weight value are excluded.
    
    Support for sample weights is available in Ensembling mode only.
- TimeSeriesForecastingJobConfig (dict) –
  
  Settings used to configure an AutoML job V2 for a time-series forecasting problem type.
  - FeatureSpecificationS3Uri (string) –
    
    A URL to the Amazon S3 data source containing additional selected features that complement the target, itemID, timestamp, and grouped columns set in TimeSeriesConfig. When not provided, the AutoML job V2 includes all the columns from the original dataset that are not already declared in TimeSeriesConfig. If provided, the AutoML job V2 only considers these additional columns as a complement to the ones declared in TimeSeriesConfig.
    
    You can input FeatureAttributeNames (optional) in JSON format as shown below:
    
    { "FeatureAttributeNames":["col1", "col2", ...] }.

    The transformations modifying specific attributes of the time-series, such as filling strategies for missing values.
    - Filling (dict) –
      
      A key value pair defining the filling method for a column, where the key is the column name and the value is an object which defines the filling logic. You can specify multiple filling methods for a single column.
      
      The supported filling methods and their corresponding options are:
      - frontfill: none (Supported only for target column)
      - middlefill: zero, value, median, mean, min, max
      - backfill: zero, value, median, mean, min, max
      - futurefill: zero, value, median, mean, min, max
      To set a filling method to a specific value, set the fill parameter to the chosen filling method value (for example "backfill" : "value"), and define the filling value in an additional parameter prefixed with “_value”. For example, to set backfill to a value of 2, you must include two parameters: "backfill": "value" and "backfill_value":"2".

      - CountryCode (string) –
        
        The country code for the holiday calendar.
        
        For the list of public holiday calendars supported by AutoML job V2, see Country Codes. Use the country code corresponding to the country of your choice.
RoleArn (string) –
[REQUIRED]

The ARN of the role that is used to access the data.
Tags (list) –
An array of key-value pairs. You can use tags to categorize your Amazon Web Services resources in different ways, such as by purpose, owner, or environment. For more information, see Tagging Amazon Web ServicesResources. Tag keys must be unique per resource.
- (dict) –
  
  A tag object that consists of a key and an optional value, used to manage metadata for SageMaker Amazon Web Services resources.
  
  You can add tags to notebook instances, training jobs, hyperparameter tuning jobs, batch transform jobs, models, labeling jobs, work teams, endpoint configurations, and endpoints. For more information on adding tags to SageMaker resources, see AddTags.
  
  For more information on adding metadata to your Amazon Web Services resources with tagging, see Tagging Amazon Web Services resources. For advice on best practices for managing Amazon Web Services resources with tagging, see Tagging Best Practices: Implement an Effective Amazon Web Services Resource Tagging Strategy.

    - (string) –
  - Subnets (list) – [REQUIRED]
    
    The ID of the subnets in the VPC to which you want to connect your training job or model. For information about the availability of specific instance types, see Supported Instance Types and Availability Zones.
    - (string) –
AutoMLJobObjective (dict) –
Specifies a metric to minimize or maximize as the objective of a job. If not specified, the default objective metric depends on the problem type. For the list of default values per problem type, see AutoMLJobObjective.

Note
For tabular problem types, you must either provide both the AutoMLJobObjective and indicate the type of supervised learning problem in AutoMLProblemTypeConfig ( TabularJobConfig.ProblemType), or none at all.
- MetricName (string) – [REQUIRED]
  
  The name of the objective metric used to measure the predictive quality of a machine learning system. During training, the model’s parameters are updated iteratively to optimize its performance based on the feedback provided by the objective metric when evaluating the model on the validation dataset.
  
  For the list of all available metrics supported by Autopilot, see Autopilot metrics.
  
  If you do not specify a metric explicitly, the default behavior is to automatically use:
  - For tabular problem types:
    - Regression: MSE.
    - Binary classification: F1.
    - Multiclass classification: Accuracy.
  - For image or text classification problem types: Accuracy
  - For time-series forecasting problem types: AverageWeightedQuantileLoss
ModelDeployConfig (dict) –
Specifies how to generate the endpoint name for an automatic one-click Autopilot model deployment.
- AutoGenerateEndpointName (boolean) –
  
  Set to True to automatically generate an endpoint name for a one-click Autopilot model deployment; set to False otherwise. The default value is False.
  
  Note
  If you set AutoGenerateEndpointName to True, do not specify the EndpointName; otherwise a 400 error is thrown.
- EndpointName (string) –
  
  Specifies the endpoint name to use for a one-click Autopilot model deployment if the endpoint name is not generated automatically.
  
  Note
  Specify the EndpointName if and only if you set AutoGenerateEndpointName to False; otherwise a 400 error is thrown.
DataSplitConfig (dict) –
This structure specifies how to split the data into train and validation datasets.

The validation and training datasets must contain the same headers. For jobs created by calling CreateAutoMLJob, the validation dataset must be less than 2 GB in size.

Note
This attribute must not be set for the time-series forecasting problem type, as Autopilot automatically splits the input dataset into training and validation sets.
- ValidationFraction (float) –
  
  The validation fraction (optional) is a float that specifies the portion of the training dataset to be used for validation. The default value is 0.2, and values must be greater than 0 and less than 1. We recommend setting this value to be less than 0.5.
