Parameters:

• options (Hash)

Options Hash (options):

• :credentials (required, Aws::CredentialProvider) —

  Your AWS credentials. This can be an instance of any one of the following classes:

  • Aws::Credentials - Used for configuring static, non-refreshing credentials.

  • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

  • Aws::SharedCredentials - Used for loading credentials from a shared file, such as ~/.aws/config.

  • Aws::AssumeRoleCredentials - Used when you need to assume a role.

  When :credentials are not configured directly, the following locations will be searched for credentials:

  • Aws.config[:credentials]
  • The :access_key_id, :secret_access_key, and :session_token options.
  • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
  • ~/.aws/credentials
  • ~/.aws/config
  • EC2 IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentails to enable retries and extended timeouts.
• :region (required, String) —

  The AWS region to connect to. The configured :region is used to determine the service :endpoint. When not passed, a default :region is search for in the following locations:

  • Aws.config[:region]

  • ENV['AWS_DEFAULT_REGION']
  • ~/.aws/credentials
  • ~/.aws/config

• :disable_host_prefix_injection (Boolean) — default: false —

  Set to true to disable SDK automatically adding host prefix to default service endpoint when available.

• :endpoint (String) —

  The client endpoint is normally constructed from the :region option. You should only configure an :endpoint when connecting to test endpoints. This should be avalid HTTP(S) URI.

• :endpoint_cache_max_entries (Integer) — default: 1000 —

  Used for the maximum size limit of the LRU cache storing endpoints data for endpoint discovery enabled operations. Defaults to 1000.

• :endpoint_cache_max_threads (Integer) — default: 10 —

  Used for the maximum threads in use for polling endpoints to be cached, defaults to 10.

  When set to true, endpoint discovery will be enabled for operations when available. Defaults to false.

• :log_formatter (Aws::Log::Formatter) — default: Aws::Log::Formatter.default —

  The log formatter.

• :log_level (Symbol) — default: :info —

  The log level to send messages to the :logger at.

• :profile (String) — default: "default" —

  Used when loading credentials from the shared credentials file at HOME/.aws/credentials. When not specified, 'default' is used.

• :retry_base_delay (Float) — default: 0.3 —

  The base delay in seconds used by the default backoff function.

• :retry_jitter (Symbol) — default: :none —

  A delay randomiser function used by the default backoff function. Some predefined functions can be referenced by name - :none, :equal, :full, otherwise a Proc that takes and returns a number.

  @see https://www.awsarchitectureblog.com/2015/03/backoff.html

• :retry_limit (Integer) — default: 3 —

  The maximum number of times to retry failed requests. Only ~ 500 level server errors and certain ~ 400 level client errors are retried. Generally, these are throttling errors, data checksum errors, networking errors, timeout errors and auth errors from expired credentials.

• :retry_max_delay (Integer) — default: 0 —

  The maximum number of seconds to delay between retries (0 for no limit) used by the default backoff function.

• :secret_access_key (String)
• :session_token (String)
• :stub_responses (Boolean) — default: false —

  Causes the client to return stubbed responses. By default fake responses are generated and returned. You can specify the response data to return or errors to raise by calling ClientStubs#stub_responses. See ClientStubs for more information.

  Please note When response stubbing is enabled, no HTTP requests are made, and retries are disabled.

• :validate_params (Boolean) — default: true —

  When true, request parameters are validated before sending the request.

• :http_proxy (URI::HTTP, String) —

  A proxy to send requests through. Formatted like 'http://proxy.com:123'.

• :http_open_timeout (Float) — default: 15 —

  The number of seconds to wait when opening a HTTP session before rasing a Timeout::Error.

• :http_read_timeout (Integer) — default: 60 —

  The default number of seconds to wait for response data. This value can safely be set per-request on the session yeidled by #session_for.

• :http_idle_timeout (Float) — default: 5 —

  The number of seconds a connection is allowed to sit idble before it is considered stale. Stale connections are closed and removed from the pool before making a request.

• :http_continue_timeout (Float) — default: 1 —

  The number of seconds to wait for a 100-continue response before sending the request body. This option has no effect unless the request has "Expect" header set to "100-continue". Defaults to nil which disables this behaviour. This value can safely be set per request on the session yeidled by #session_for.

• :http_wire_trace (Boolean) — default: false —

  When true, HTTP debug output will be sent to the :logger.

• :ssl_verify_peer (Boolean) — default: true —

  When true, SSL peer certificates are verified when establishing a connection.

• :ssl_ca_bundle (String) —

• :ssl_ca_directory (String) —

  Full path of the directory that contains the unbundled SSL certificate authority files for verifying peer certificates. If you do not pass :ssl_ca_bundle or :ssl_ca_directory the the system default will be used if available.

Instance Method Details

#get_personalized_ranking(params = {}) ⇒ Types::GetPersonalizedRankingResponse

Re-ranks a list of recommended items for the given user. The first item in the list is deemed the most likely item to be of interest to the user.

The solution backing the campaign must have been created using a recipe of type PERSONALIZED_RANKING.

Examples:

Request syntax with placeholder values

resp = client.get_personalized_ranking({
  campaign_arn: "Arn", # required
  input_list: ["ItemID"], # required
  user_id: "UserID", # required
})

Response structure

resp.personalized_ranking #=> Array
resp.personalized_ranking[0].item_id #=> String

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :campaign_arn (required, String) —

  The Amazon Resource Name (ARN) of the campaign to use for generating the personalized ranking.

• :input_list (required, Array<String>) —

  A list of items (itemId's) to rank. If an item was not included in the training dataset, the item is appended to the end of the reranked list.

• :user_id (required, String) —

  The user for which you want the campaign to provide a personalized ranking.

Returns:

• (Types::GetPersonalizedRankingResponse) —

  Returns a response object which responds to the following methods:

  • #personalized_ranking => Array<Types::PredictedItem>

• AWS API Documentation

# File 'gems/aws-sdk-personalizeruntime/lib/aws-sdk-personalizeruntime/client.rb', line 300

def get_personalized_ranking(params = {}, options = {})
  req = build_request(:get_personalized_ranking, params)
  req.send_request(options)
end

#get_recommendations(params = {}) ⇒ Types::GetRecommendationsResponse

Returns a list of recommended items. The required input depends on the recipe type used to create the solution backing the campaign, as follows:

• RELATED_ITEMS - itemId required, userId not used

• USER_PERSONALIZATION - itemId optional, userId required

Campaigns that are backed by a solution created using a recipe of type PERSONALIZED_RANKING use the API.

Examples:

Request syntax with placeholder values

resp = client.get_recommendations({
  campaign_arn: "Arn", # required
  item_id: "ItemID",
  user_id: "UserID",
  num_results: 1,
})

Response structure

resp.item_list #=> Array
