Methods
#disable_early_stopping
def disable_early_stopping() -> ::Boolean- (::Boolean) — Use the entire training budget. This disables the early stopping feature. By default, the early stopping feature is enabled, which means that AutoML Tables might stop training before the entire training budget has been used.
#disable_early_stopping=
def disable_early_stopping=(value) -> ::Boolean- value (::Boolean) — Use the entire training budget. This disables the early stopping feature. By default, the early stopping feature is enabled, which means that AutoML Tables might stop training before the entire training budget has been used.
- (::Boolean) — Use the entire training budget. This disables the early stopping feature. By default, the early stopping feature is enabled, which means that AutoML Tables might stop training before the entire training budget has been used.
#input_feature_column_specs
def input_feature_column_specs() -> ::Array<::Google::Cloud::AutoML::V1beta1::ColumnSpec>-
(::Array<::Google::Cloud::AutoML::V1beta1::ColumnSpec>) —
Column specs of the dataset's primary table's columns, on which the model is trained and which are used as the input for predictions. The
target_column as well as, according to dataset's state upon model creation,
weight_column, and
ml_use_column must never be included here.
Only 3 fields are used:
name - May be set on CreateModel, if set only the columns specified are used, otherwise all primary table's columns (except the ones listed above) are used for the training and prediction input.
display_name - Output only.
data_type - Output only.
#input_feature_column_specs=
def input_feature_column_specs=(value) -> ::Array<::Google::Cloud::AutoML::V1beta1::ColumnSpec>-

#optimization_objective
def optimization_objective() -> ::String-
(::String) — Objective function the model is optimizing towards. The training process
creates a model that maximizes/minimizes the value of the objective
function over the validation set.
The supported optimization objectives depend on the prediction type. If the field is not set, a default objective function is used.
CLASSIFICATION_BINARY: "MAXIMIZE_AU_ROC" (default) - Maximize the area under the receiver operating characteristic (ROC) curve. "MINIMIZE_LOG_LOSS" - Minimize log loss. "MAXIMIZE_AU_PRC" - Maximize the area under the precision-recall curve. "MAXIMIZE_PRECISION_AT_RECALL" - Maximize precision for a specified recall value. "MAXIMIZE_RECALL_AT_PRECISION" - Maximize recall for a specified precision value.
CLASSIFICATION_MULTI_CLASS : "MINIMIZE_LOG_LOSS" (default) - Minimize log loss.
REGRESSION: "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).
