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

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

  • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

  • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

  • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

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

  • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

  • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

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

  • Aws.config[:credentials]

  • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
  • ~/.aws/credentials
  • ~/.aws/config
  • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentails or Aws::ECSCredentials 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 searched for in the following locations:

  Required for publishing client metrics. The port that the client side monitoring agent is running on, where client metrics will be published via UDP.

• :client_side_monitoring_publisher (Aws::ClientSideMonitoring::Publisher) — default: Aws::ClientSideMonitoring::Publisher —

  Allows you to provide a custom client-side monitoring publisher class. By default, will use the Client Side Monitoring Agent Publisher.

• :convert_params (Boolean) — default: true —

  When true, an attempt is made to coerce request parameters into the required types.

• :correct_clock_skew (Boolean) — default: true —

  Used only in standard and adaptive retry modes. Specifies whether to apply a clock skew correction and retry requests with skewed client clocks.

• :disable_host_prefix_injection (Boolean) — default: false —

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

  • legacy - The pre-existing retry behavior. This is default value if no retry mode is provided.

  • standard - A standardized set of retry rules across the AWS SDKs. This includes support for retry quotas, which limit the number of unsuccessful retries a client can make.

  • adaptive - An experimental retry mode that includes all the functionality of standard mode along with automatic client side throttling. This is a provisional mode that may change behavior in the future.

• :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.

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

• :http_idle_timeout (Float) — default: 5 —

  The number of seconds a connection is allowed to sit idle 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.

• :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.

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
  context: {
    "AttributeName" => "AttributeValue",
  },
  filter_arn: "Arn",
  filter_values: {
    "FilterAttributeName" => "FilterAttributeValue",
  },
})

Response structure

resp.personalized_ranking #=> Array
resp.personalized_ranking[0].item_id #=> String
resp.personalized_ranking[0].score #=> Float
resp.recommendation_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 (by itemId) to rank. If an item was not included in the training dataset, the item is appended to the end of the reranked list. The maximum is 500.

• :user_id (required, String) —

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

• :context (Hash<String,String>) —

  The contextual metadata to use when getting recommendations. Contextual metadata includes any interaction information that might be relevant when getting a user's recommendations, such as the user's current location or device type.

• :filter_arn (String) —

  The Amazon Resource Name (ARN) of a filter you created to include items or exclude items from recommendations for a given user. For more information, see Filtering Recommendations.

• :filter_values (Hash<String,String>) —

  The values to use when filtering recommendations. For each placeholder parameter in your filter expression, provide the parameter name (in matching case) as a key and the filter value(s) as the corresponding value. Separate multiple values for one parameter with a comma.

  For filter expressions that use an INCLUDE element to include items, you must provide values for all parameters that are defined in the expression. For filters with expressions that use an EXCLUDE element to exclude items, you can omit the filter-values.In this case, Amazon Personalize doesn't use that portion of the expression to filter recommendations.

  For more information, see Filtering Recommendations.

Returns:

• (Types::GetPersonalizedRankingResponse) —

  Returns a response object which responds to the following methods:

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