Reference documentation and code samples for the Vertex AI v1beta1 API class StudySpec.Types.MedianAutomatedStoppingSpec.
The median automated stopping rule stops a pending Trial if the Trial's
best objective_value is strictly below the median 'performance' of all
completed Trials reported up to the Trial's last measurement.
Currently, 'performance' refers to the running average of the objective
values reported by the Trial in each measurement.
True if median automated stopping rule applies on
[Measurement.elapsed_duration][google.cloud.aiplatform.v1beta1.Measurement.elapsed_duration].
It means that elapsed_duration field of latest measurement of current
Trial is used to compute median objective value for each completed
Trials.
