Reference documentation and code samples for the Google Cloud Ai Platform V1 Client class 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.
