Basic example

require "google/cloud/ai_platform/v1"

# Call the lookup_study method.
result = client.lookup_study request

# The returned object is of type Google::Cloud::AIPlatform::V1::Study.

#operations_client

def operations_client() -> ::Google::Cloud::AIPlatform::V1::VizierService::Rest::Operations

Get the associated client for long-running operations.

Returns

#stop_trial

def stop_trial(request, options = nil) -> ::Google::Cloud::AIPlatform::V1::Trial
def stop_trial(name: nil) -> ::Google::Cloud::AIPlatform::V1::Trial

Stops a Trial.

Overloads 
def stop_trial(request, options = nil) -> ::Google::Cloud::AIPlatform::V1::Trial
Pass arguments to stop_trial via a request object, either of type StopTrialRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::AIPlatform::V1::StopTrialRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def stop_trial(name: nil) -> ::Google::Cloud::AIPlatform::V1::Trial
Pass arguments to stop_trial via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameter
  • name (::String) — Required. The Trial's name. Format: projects/{project}/locations/{location}/studies/{study}/trials/{trial}
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
Returns
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.

#suggest_trials

def suggest_trials(request, options = nil) -> ::Gapic::Operation
def suggest_trials(parent: nil, suggestion_count: nil, client_id: nil, contexts: nil) -> ::Gapic::Operation

Adds one or more Trials to a Study, with parameter values suggested by Vertex AI Vizier. Returns a long-running operation associated with the generation of Trial suggestions. When this long-running operation succeeds, it will contain a SuggestTrialsResponse.

Overloads 
def suggest_trials(request, options = nil) -> ::Gapic::Operation
Pass arguments to suggest_trials via a request object, either of type SuggestTrialsRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::AIPlatform::V1::SuggestTrialsRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def suggest_trials(parent: nil, suggestion_count: nil, client_id: nil, contexts: nil) -> ::Gapic::Operation
Pass arguments to suggest_trials via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • parent (::String) — Required. The project and location that the Study belongs to. Format: projects/{project}/locations/{location}/studies/{study}
  • suggestion_count (::Integer) — Required. The number of suggestions requested. It must be positive.
  • client_id (::String) — Required. The identifier of the client that is requesting the suggestion.

    If multiple SuggestTrialsRequests have the same client_id, the service will return the identical suggested Trial if the Trial is pending, and provide a new Trial if the last suggested Trial was completed.

  • contexts (::Array<::Google::Cloud::AIPlatform::V1::TrialContext, ::Hash>) — Optional. This allows you to specify the "context" for a Trial; a context is a slice (a subspace) of the search space.

    Typical uses for contexts: 1) You are using Vizier to tune a server for best performance, but there's a strong weekly cycle. The context specifies the day-of-week. This allows Tuesday to generalize from Wednesday without assuming that everything is identical. 2) Imagine you're optimizing some medical treatment for people. As they walk in the door, you know certain facts about them (e.g. sex, weight, height, blood-pressure). Put that information in the context, and Vizier will adapt its suggestions to the patient. 3) You want to do a fair A/B test efficiently. Specify the "A" and "B" conditions as contexts, and Vizier will generalize between "A" and "B" conditions. If they are similar, this will allow Vizier to converge to the optimum faster than if "A" and "B" were separate Studies. NOTE: You can also enter contexts as REQUESTED Trials, e.g. via the CreateTrial() RPC; that's the asynchronous option where you don't need a close association between contexts and suggestions.

    NOTE: All the Parameters you set in a context MUST be defined in the Study. NOTE: You must supply 0 or $suggestion_count contexts. If you don't supply any contexts, Vizier will make suggestions from the full search space specified in the StudySpec; if you supply a full set of context, each suggestion will match the corresponding context. NOTE: A Context with no features set matches anything, and allows suggestions from the full search space. NOTE: Contexts MUST lie within the search space specified in the StudySpec. It's an error if they don't. NOTE: Contexts preferentially match ACTIVE then REQUESTED trials before new suggestions are generated. NOTE: Generation of suggestions involves a match between a Context and (optionally) a REQUESTED trial; if that match is not fully specified, a suggestion will be geneated in the merged subspace.
