Methods

#disable_early_stopping

def disable_early_stopping() -> ::Boolean
Returns
  • (::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
Parameter
  • 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.
Returns
  • (::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>
Returns
  • (::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.
