Methods

getAutoregressiveOrder()

public abstract long getAutoregressiveOrder()

The number of Trial measurements used in autoregressive model for value prediction. A trial won't be considered early stopping if has fewer measurement points.

int64 autoregressive_order = 3;

Returns

Type	Description
long	The autoregressiveOrder.

getLearningRateParameterName()

public abstract String getLearningRateParameterName()

The hyper-parameter name used in the tuning job that stands for learning rate. Leave it blank if learning rate is not in a parameter in tuning. The learning_rate is used to estimate the objective value of the ongoing trial.

string learning_rate_parameter_name = 4;

Returns

Type	Description
String	The learningRateParameterName.

getLearningRateParameterNameBytes()

public abstract ByteString getLearningRateParameterNameBytes()

The hyper-parameter name used in the tuning job that stands for learning rate. Leave it blank if learning rate is not in a parameter in tuning. The learning_rate is used to estimate the objective value of the ongoing trial.

string learning_rate_parameter_name = 4;

Returns

Type	Description
ByteString	The bytes for learningRateParameterName.

getMaxNumSteps()

public abstract long getMaxNumSteps()

Steps used in predicting the final objective for early stopped trials. In general, it's set to be the same as the defined steps in training / tuning. When use_steps is false, this field is set to the maximum elapsed seconds.

int64 max_num_steps = 1;

Returns

Type	Description
long	The maxNumSteps.

getMinNumSteps()

public abstract long getMinNumSteps()

Minimum number of steps for a trial to complete. Trials which do not have a measurement with num_steps > min_num_steps won't be considered for early stopping. It's ok to set it to 0, and a trial can be early stopped at any stage. By default, min_num_steps is set to be one-tenth of the max_num_steps. When use_steps is false, this field is set to the minimum elapsed seconds.

int64 min_num_steps = 2;

Returns

Type	Description
long	The minNumSteps.

getUseSeconds()

public abstract boolean getUseSeconds()

This bool determines whether or not the rule is applied based on elapsed_secs or steps. If use_seconds

false, the early stopping decision is made according to the predicted objective values according to the target steps. If use_seconds

true, elapsed_secs is used instead of steps. Also, in this case, the parameters max_num_steps and min_num_steps are overloaded to contain max_elapsed_seconds and min_elapsed_seconds.

bool use_seconds = 5;

Returns

Type	Description
boolean	The useSeconds.
