public String getOptimizationObjective()
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).

public ColumnSpec getTargetColumnSpec()
Column spec of the dataset's primary table's column the model is
predicting. Snapshotted when model creation started.
Only 3 fields are used:

corresponding to the current target_column_spec_id of the dataset
the model is trained from is used.
If neither is set, CreateModel will error.

public long getTrainBudgetMilliNodeHours()
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.

| Type | Description |
long | The trainBudgetMilliNodeHours.

public long getTrainCostMilliNodeHours()
Output only. The actual training cost of the model, expressed in milli
node hours, i.e. 1,000 value in this field means 1 node hour. Guaranteed
to not exceed the train budget.
