Vertex AI Vizier
Vertex AI Vizier is a black-box optimization service that helps tune hyperparameters in complex machine learning (ML) models.
Vertex AI Vizier optimizes your model’s output by tuning the hyperparameters for you.
Black-box optimization is the optimization of a system that meets either of the following criteria:
- Doesn’t have a known objective function to evaluate.
- Is too costly to evaluate by using the objective function, usually due to the complexity of the system.
How Vertex AI Vizier works
The following sections define terms, behavior, and available values that you can use with Vertex AI Vizier to optimize your ML model or function.
Study configurations
A study configuration is the definition of the optimization problem that you are trying to solve. It includes the result you would like to optimize and the hyperparameters or parameters that affect that result.
Studies and trials
A study is the implementation of a study configuration.
A trial is a specific set of input values that produce a measured outcome relative to your goals.
