Reference documentation and code samples for the Google Cloud Ai Platform V1 Client class DecayCurveAutomatedStoppingSpec.
The decay curve automated stopping rule builds a Gaussian Process
Regressor to predict the final objective value of a Trial based on the
already completed Trials and the intermediate measurements of the current
Trial. Early stopping is requested for the current Trial if there is very
low probability to exceed the optimal value found so far.
