    Attributes:
        target_column (str):
            The name of the column that the model is to
            predict.
        time_series_identifier_column (str):
            The name of the column that identifies the
            time series.
        time_column (str):
            The name of the column that identifies time
            order in the time series.
        transformations (Sequence[google.cloud.aiplatform.v1beta1.schema.trainingjob.definition_v1beta1.types.AutoMlForecastingInputs.Transformation]):
            Each transformation will apply transform
            function to given input column. And the result
            will be used for training. When creating
            transformation for BigQuery Struct column, the
            column should be flattened using "." as the
            delimiter.
        optimization_objective (str):
            Objective function the model is optimizing towards. The
            training process creates a model that optimizes the value of
            the objective function over the validation set.

            The supported optimization objectives:

            -  "minimize-rmse" (default) - Minimize root-mean-squared
               error (RMSE).

            -  "minimize-mae" - Minimize mean-absolute error (MAE).

            -  "minimize-rmsle" - Minimize root-mean-squared log error
               (RMSLE).

            -  "minimize-rmspe" - Minimize root-mean-squared percentage
               error (RMSPE).

            -  "minimize-wape-mae" - Minimize the combination of
               weighted absolute percentage error (WAPE) and
               mean-absolute-error (MAE).

            -  "minimize-quantile-loss" - Minimize the quantile loss at
               the quantiles defined in ``quantiles``.
        train_budget_milli_node_hours (int):
            Required. The train budget of creating this
            model, expressed in milli node hours i.e. 1,000
            value in this field means 1 node hour.
            The training cost of the model will not exceed
            this budget. The final cost will be attempted to
            be close to the budget, though may end up being
            (even) noticeably smaller - at the backend's
            discretion. This especially may happen when
            further model training ceases to provide any
            improvements.
            If the budget is set to a value known to be
            insufficient to train a model for the given
            dataset, the training won't be attempted and
            will error.

            The train budget must be between 1,000 and
            72,000 milli node hours, inclusive.
        weight_column (str):
            Column name that should be used as the weight
            column. Higher values in this column give more
            importance to the row during model training. The
            column must have numeric values between 0 and
            10000 inclusively; 0 means the row is ignored
            for training. If weight column field is not set,
            then all rows are assumed to have equal weight
            of 1.
        time_series_attribute_columns (Sequence[str]):
            Column names that should be used as attribute
            columns. The value of these columns does not
            vary as a function of time. For example, store
            ID or item color.
        unavailable_at_forecast_columns (Sequence[str]):
            Names of columns that are unavailable when a forecast is
            requested. This column contains information for the given
            entity (identified by the time_series_identifier_column)
            that is unknown before the forecast For example, actual
            weather on a given day.
        available_at_forecast_columns (Sequence[str]):
            Names of columns that are available and provided when a
            forecast is requested. These columns contain information for
            the given entity (identified by the
            time_series_identifier_column column) that is known at
            forecast. For example, predicted weather for a specific day.
        data_granularity (google.cloud.aiplatform.v1beta1.schema.trainingjob.definition_v1beta1.types.AutoMlForecastingInputs.Granularity):
            Expected difference in time granularity
            between rows in the data.
        forecast_horizon (int):
            The amount of time into the future for which forecasted
            values for the target are returned. Expressed in number of
            units defined by the ``data_granularity`` field.
        context_window (int):
            The amount of time into the past training and prediction
            data is used for model training and prediction respectively.
            Expressed in number of units defined by the
            ``data_granularity`` field.
        export_evaluated_data_items_config (google.cloud.aiplatform.v1beta1.schema.trainingjob.definition_v1beta1.types.ExportEvaluatedDataItemsConfig):
            Configuration for exporting test set
            predictions to a BigQuery table. If this
            configuration is absent, then the export is not
            performed.
        quantiles (Sequence[float]):
            Quantiles to use for minimize-quantile-loss
            ``optimization_objective``. Up to 5 quantiles are allowed of
            values between 0 and 1, exclusive. Required if the value of
            optimization_objective is minimize-quantile-loss. Represents
            the percent quantiles to use for that objective. Quantiles
            must be unique.
        validation_options (str):
            Validation options for the data validation component. The
            available options are:

            -  "fail-pipeline" - default, will validate against the
               validation and fail the pipeline if it fails.

            -  "ignore-validation" - ignore the results of the
               validation and continue
        additional_experiments (Sequence[str]):
            Additional experiment flags for the time
            series forcasting training.
