#add_trial_measurement(request, options = nil) ⇒ ::Google::Cloud::AIPlatform::V1::Trial #add_trial_measurement(trial_name: nil, measurement: nil) ⇒ ::Google::Cloud::AIPlatform::V1::Trial

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

Examples:

Basic example

require "google/cloud/ai_platform/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AIPlatform::V1::VizierService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AIPlatform::V1::AddTrialMeasurementRequest.new

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

# The returned object is of type Google::Cloud::AIPlatform::V1::Trial.
p result

Overloads:

  • #add_trial_measurement(request, options = nil) ⇒ ::Google::Cloud::AIPlatform::V1::Trial

    Pass arguments to add_trial_measurement via a request object, either of type AddTrialMeasurementRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::AIPlatform::V1::AddTrialMeasurementRequest, ::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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #add_trial_measurement(trial_name: nil, measurement: nil) ⇒ ::Google::Cloud::AIPlatform::V1::Trial

    Pass arguments to add_trial_measurement 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:

    • trial_name (::String) (defaults to: nil) —

      Required. The name of the trial to add measurement. Format: projects/{project}/locations/{location}/studies/{study}/trials/{trial}

    • measurement (::Google::Cloud::AIPlatform::V1::Measurement, ::Hash) (defaults to: nil) —

      Required. The measurement to be added to a Trial.

#list_optimal_trials(request, options = nil) ⇒ ::Google::Cloud::AIPlatform::V1::ListOptimalTrialsResponse #list_optimal_trials(parent: nil) ⇒ ::Google::Cloud::AIPlatform::V1::ListOptimalTrialsResponse

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

Examples:

Basic example

require "google/cloud/ai_platform/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AIPlatform::V1::VizierService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AIPlatform::V1::ListOptimalTrialsRequest.new

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

# The returned object is of type Google::Cloud::AIPlatform::V1::ListOptimalTrialsResponse.
p result

Overloads:

  • #list_optimal_trials(request, options = nil) ⇒ ::Google::Cloud::AIPlatform::V1::ListOptimalTrialsResponse

    Pass arguments to list_optimal_trials via a request object, either of type ListOptimalTrialsRequest or an equivalent Hash.

    Parameters:

#suggest_trials(request, options = nil) ⇒ ::Gapic::Operation #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.

Examples:

Basic example

require "google/cloud/ai_platform/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AIPlatform::V1::VizierService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AIPlatform::V1::SuggestTrialsRequest.new

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

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #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) (defaults to: nil) —

      Required. The project and location that the Study belongs to. Format: projects/{project}/locations/{location}/studies/{study}

    • suggestion_count (::Integer) (defaults to: nil) —

      Required. The number of suggestions requested. It must be positive.

    • client_id (::String) (defaults to: nil) —

      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>) (defaults to: nil) —

      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.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
