public static interface VizierServiceGrpc.AsyncService

Vertex AI Vizier API. Vertex AI Vizier is a service to solve blackbox optimization problems, such as tuning machine learning hyperparameters and searching over deep learning architectures.

Methods

addTrialMeasurement(AddTrialMeasurementRequest request, StreamObserver<Trial> responseObserver)

public default void addTrialMeasurement(AddTrialMeasurementRequest request, StreamObserver<Trial> responseObserver)

Adds a measurement of the objective metrics to a Trial. This measurement is assumed to have been taken before the Trial is complete.

Parameters
Name	Description
request	AddTrialMeasurementRequest
responseObserver	io.grpc.stub.StreamObserver<Trial>

checkTrialEarlyStoppingState(CheckTrialEarlyStoppingStateRequest request, StreamObserver<Operation> responseObserver)

public default void checkTrialEarlyStoppingState(CheckTrialEarlyStoppingStateRequest request, StreamObserver<Operation> responseObserver)

Checks whether a Trial should stop or not. Returns a long-running operation. When the operation is successful, it will contain a CheckTrialEarlyStoppingStateResponse.

Parameters
Name	Description
request	CheckTrialEarlyStoppingStateRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>

completeTrial(CompleteTrialRequest request, StreamObserver<Trial> responseObserver)

public default void completeTrial(CompleteTrialRequest request, StreamObserver<Trial> responseObserver)

Marks a Trial as complete.

Parameters
Name	Description
request	CompleteTrialRequest
responseObserver	io.grpc.stub.StreamObserver<Trial>

createStudy(CreateStudyRequest request, StreamObserver<Study> responseObserver)

public default void createStudy(CreateStudyRequest request, StreamObserver<Study> responseObserver)

Creates a Study. A resource name will be generated after creation of the Study.

Parameters
Name	Description
request	CreateStudyRequest
responseObserver	io.grpc.stub.StreamObserver<Study>

createTrial(CreateTrialRequest request, StreamObserver<Trial> responseObserver)

public default void createTrial(CreateTrialRequest request, StreamObserver<Trial> responseObserver)

Adds a user provided Trial to a Study.

Parameters
Name	Description
request	CreateTrialRequest
responseObserver	io.grpc.stub.StreamObserver<Trial>

deleteStudy(DeleteStudyRequest request, StreamObserver<Empty> responseObserver)

public default void deleteStudy(DeleteStudyRequest request, StreamObserver<Empty> responseObserver)

Deletes a Study.

Parameters
Name	Description
request	DeleteStudyRequest
responseObserver	io.grpc.stub.StreamObserver<Empty>

deleteTrial(DeleteTrialRequest request, StreamObserver<Empty> responseObserver)

public default void deleteTrial(DeleteTrialRequest request, StreamObserver<Empty> responseObserver)

Deletes a Trial.

Parameters
Name	Description
request	DeleteTrialRequest
responseObserver	io.grpc.stub.StreamObserver<Empty>

getStudy(GetStudyRequest request, StreamObserver<Study> responseObserver)

public default void getStudy(GetStudyRequest request, StreamObserver<Study> responseObserver)

Gets a Study by name.

Parameters
Name	Description
request	GetStudyRequest
responseObserver	io.grpc.stub.StreamObserver<Study>

getTrial(GetTrialRequest request, StreamObserver<Trial> responseObserver)

public default void getTrial(GetTrialRequest request, StreamObserver<Trial> responseObserver)

Gets a Trial.

Parameters
Name	Description
request	GetTrialRequest
responseObserver	io.grpc.stub.StreamObserver<Trial>

listOptimalTrials(ListOptimalTrialsRequest request, StreamObserver<ListOptimalTrialsResponse> responseObserver)

public default void listOptimalTrials(ListOptimalTrialsRequest request, StreamObserver<ListOptimalTrialsResponse> responseObserver)

Lists the pareto-optimal Trials for multi-objective Study or the optimal Trials for single-objective Study. The definition of pareto-optimal can be checked in wiki page. https://en.wikipedia.org/wiki/Pareto_efficiency

Parameters
