Configuration for ConvexAutomatedStoppingSpec.
When there are enough completed trials (configured by
min_measurement_count), for pending trials with enough measurements and
steps, the policy first computes an overestimate of the objective value at
max_num_steps according to the slope of the incomplete objective value
curve. No prediction can be made if the curve is completely flat. If the
overestimation is worse than the best objective value of the completed
trials, this pending trial will be early-stopped, but a last measurement
will be added to the pending trial with max_num_steps and predicted
objective value from the autoregression model.

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.
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.
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. If not defined, it will learn it from the completed trials. When
use_steps is false, this field is set to the maximum elapsed seconds.
The minimal number of measurements in a Trial. Early-stopping checks
will not trigger if less than min_measurement_count+1 completed trials or
pending trials with less than min_measurement_count measurements. If not
defined, the default value is 5.
Minimum number of steps for a trial to complete. Trials which do not have
a measurement with step_count > min_step_count 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_step_count is set to be one-tenth of the
max_step_count.
When use_elapsed_duration is true, this field is set to the minimum
elapsed seconds.
This bool determines whether or not the rule is applied based on
elapsed_secs or steps. If use_elapsed_duration
false, the early stopping
decision is made according to the predicted objective values according to
the target steps. If use_elapsed_duration
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.
