ObservationNoise(value)

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.

Values: OBSERVATION_NOISE_UNSPECIFIED (0): The default noise level chosen by Vertex AI. LOW (1): Vertex AI assumes that the objective function is (nearly) perfectly reproducible, and will never repeat the same Trial parameters. HIGH (2): Vertex AI will estimate the amount of noise in metric evaluations, it may repeat the same Trial parameters more than once.
