Reference documentation and code samples for the Vertex AI V1 API module Google::Cloud::AIPlatform::V1::StudySpec::ObservationNoise.
Describes the noise level of the repeated observations.
"Noisy" means that the repeated observations with the same Trial parameters
may lead to different metric evaluations.
Constants
OBSERVATION_NOISE_UNSPECIFIED
value: 0 The default noise level chosen by Vertex AI.
LOW
value: 1 Vertex AI assumes that the objective function is (nearly)
perfectly reproducible, and will never repeat the same Trial
parameters.
HIGH
value: 2 Vertex AI will estimate the amount of noise in metric
evaluations, it may repeat the same Trial parameters more than once.
