GoogleCloudAiplatformV1StudySpecConvexAutomatedStoppingSpec class

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.

learningRateParameterName ↔ String?

The hyper-parameter name used in the tuning job that stands for learning rate.

getter/setter pair

maxStepCount ↔ String?

Steps used in predicting the final objective for early stopped trials.

getter/setter pair

minMeasurementCount ↔ String?

The minimal number of measurements in a Trial.

getter/setter pair

minStepCount ↔ String?

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

updateAllStoppedTrials ↔ bool?

ConvexAutomatedStoppingSpec by default only updates the trials that needs to be early stopped using a newly trained auto-regressive model.

getter/setter pair

useElapsedDuration ↔ bool?

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