Full resource name of the format: # \\{name=projects/*/locations/global/catalogs/default_catalog/eventStores/default_event_store/placements/*} # The id of the recommendation engine placement. This id is used to identify # the set of models that will be used to make the prediction. # # We currently support three placements with the following IDs by default: # # * `shopping_cart`: Predicts items frequently bought together with one or # more catalog items in the same shopping session. Commonly displayed after # `add-to-cart` events, on product detail pages, or on the shopping cart # page. # # * `home_page`: Predicts the next product that a user will most likely # engage with or purchase based on the shopping or viewing history of the # specified `userId` or `visitorId`. For example - Recommendations for you. # # * `product_detail`: Predicts the next product that a user will most likely # engage with or purchase. The prediction is based on the shopping or # viewing history of the specified `userId` or `visitorId` and its # relevance to a specified `CatalogItem`. Typically used on product detail # pages. For example - More items like this. # # * `recently_viewed_default`: Returns up to 75 items recently viewed by the # specified `userId` or `visitorId`, most recent ones first. Returns # nothing if neither of them has viewed any items yet. For example - # Recently viewed. # # The full list of available placements can be seen at # https://console.cloud.google.com/recommendation/datafeeds/default_catalog/dashboard # @param user_event [::Google::Cloud::RecommendationEngine::V1beta1::UserEvent, ::Hash] # Required. Context about the user, what they are looking at and what action # they took to trigger the predict request. Note that this user event detail # won't be ingested to userEvent logs. Thus, a separate userEvent write # request is required for event logging. # @param page_size [::Integer] # Optional. Maximum number of results to return per page. Set this property # to the number of prediction results required. If zero, the service will # choose a reasonable default. # @param page_token [::String] # Optional. The previous PredictResponse.next_page_token. # @param filter [::String] # Optional. Filter for restricting prediction results. Accepts values for # tags and the `filterOutOfStockItems` flag. # # * Tag expressions. Restricts predictions to items that match all of the # specified tags. Boolean operators `OR` and `NOT` are supported if the # expression is enclosed in parentheses, and must be separated from the # tag values by a space. `-"tagA"` is also supported and is equivalent to # `NOT "tagA"`. Tag values must be double quoted UTF-8 encoded strings # with a size limit of 1 KiB. # # * filterOutOfStockItems. Restricts predictions to items that do not have a # stockState value of OUT_OF_STOCK. # # Examples: # # * tag=("Red" OR "Blue") tag="New-Arrival" tag=(NOT "promotional") # * filterOutOfStockItems tag=(-"promotional") # * filterOutOfStockItems # @param dry_run [::Boolean] # Optional. Use dryRun mode for this prediction query. If set to true, a # dummy model will be used that returns arbitrary catalog items. # Note that the dryRun mode should only be used for testing the API, or if # the model is not ready. # @param params [::Hash{::String => ::Google::Protobuf::Value, ::Hash}] # Optional. Additional domain specific parameters for the predictions. # # Allowed values: # # * `returnCatalogItem`: Boolean. If set to true, the associated catalogItem # object will be returned in the # `PredictResponse.PredictionResult.itemMetadata` object in the method # response. # * `returnItemScore`: Boolean. If set to true, the prediction 'score' # corresponding to each returned item will be set in the `metadata` # field in the prediction response. The given 'score' indicates the # probability of an item being clicked/purchased given the user's context # and history. # @param labels [::Hash{::String => ::String}] # Optional. The labels for the predict request. # # * Label keys can contain lowercase letters, digits and hyphens, must start # with a letter, and must end with a letter or digit. # * Non-zero label values can contain lowercase letters, digits and hyphens, # must start with a letter, and must end with a letter or digit. # * No more than 64 labels can be associated with a given request. # # See https://goo.gl/xmQnxf for more information on and examples of labels. # # @yield [response, operation] Access the result along with the RPC operation # @yieldparam response [::Gapic::PagedEnumerable<::Google::Cloud::RecommendationEngine::V1beta1::PredictResponse::PredictionResult>] # @yieldparam operation [::GRPC::ActiveCall::Operation] # # @return [::Gapic::PagedEnumerable<::Google::Cloud::RecommendationEngine::V1beta1::PredictResponse::PredictionResult>] # # @raise [::Google::Cloud::Error] if the RPC is aborted. # def predict request, options = nil raise ::ArgumentError, "request must be provided" if request.nil? request = ::Gapic::Protobuf.coerce request, to: ::Google::Cloud::RecommendationEngine::V1beta1::PredictRequest # Converts hash and nil to an options object options = ::Gapic::CallOptions.new(**options.to_h) if options.respond_to? :to_h # Customize the options with defaults metadata = @config.rpcs.predict.metadata.to_h # Set x-goog-api-client and x-goog-user-project headers metadata[:"x-goog-api-client"] ||= ::Gapic::Headers.x_goog_api_client \ lib_name: @config.lib_name, lib_version: @config.lib_version, gapic_version: ::Google::Cloud::RecommendationEngine::V1beta1::VERSION metadata[:"x-goog-user-project"] = @quota_project_id if @quota_project_id header_params = { "name" => request.name } request_params_header = header_params.map { |k, v| "#{k}=#{v}" }.join("&") metadata[:"x-goog-request-params"] ||= request_params_header options.apply_defaults timeout: @config.rpcs.predict.timeout, metadata: metadata, retry_policy: @config.rpcs.predict.retry_policy options.apply_defaults metadata: @config.metadata, retry_policy: @config.retry_policy @prediction_service_stub.call_rpc :predict, request, options: options do |response, operation| response = ::Gapic::PagedEnumerable.new @prediction_service_stub, :predict, request, response, operation, options yield response, operation if block_given? return response end rescue ::GRPC::BadStatus => e raise ::Google::Cloud::Error.from_error(e) end ## # Configuration class for the PredictionService API. # # This class represents the configuration for PredictionService, # providing control over timeouts, retry behavior, logging, transport # parameters, and other low-level controls.
