observationNoise property

String? observationNoise
getter/setter pair

The observation noise level of the study.

Currently only supported by the Vertex AI Vizier service. Not supported by HyperparameterTuningJob or TrainingPipeline. Possible string values are:

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

Implementation
