Class PredictionServiceClient

  • All Implemented Interfaces:
    com.google.api.gax.core.BackgroundResource, AutoCloseable

    @BetaApi

    public class PredictionServiceClient
    extends Object
    implements com.google.api.gax.core.BackgroundResource
    Service Description: AutoML Prediction API.

    On any input that is documented to expect a string parameter in snake_case or kebab-case, either of those cases is accepted.

    This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

    
     // This snippet has been automatically generated and should be regarded as a code template only.
     // It will require modifications to work:
     // - It may require correct/in-range values for request initialization.
     // - It may require specifying regional endpoints when creating the service client as shown in
     // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
     try (PredictionServiceClient predictionServiceClient = PredictionServiceClient.create()) {
       ModelName name = ModelName.of("[PROJECT]", "[LOCATION]", "[MODEL]");
       ExamplePayload payload = ExamplePayload.newBuilder().build();
       Map<String, String> params = new HashMap<>();
       PredictResponse response = predictionServiceClient.predict(name, payload, params);
     }
     

    Note: close() needs to be called on the PredictionServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

    The surface of this class includes several types of Java methods for each of the API's methods:

    1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
    2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
    3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

    See the individual methods for example code.

    Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

    This class can be customized by passing in a custom instance of PredictionServiceSettings to create(). For example:

    To customize credentials:

    
     // This snippet has been automatically generated and should be regarded as a code template only.
     // It will require modifications to work:
     // - It may require correct/in-range values for request initialization.
     // - It may require specifying regional endpoints when creating the service client as shown in
     // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
     PredictionServiceSettings predictionServiceSettings =
         PredictionServiceSettings.newBuilder()
             .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
             .build();
     PredictionServiceClient predictionServiceClient =
         PredictionServiceClient.create(predictionServiceSettings);
     

    To customize the endpoint:

    
     // This snippet has been automatically generated and should be regarded as a code template only.
     // It will require modifications to work:
     // - It may require correct/in-range values for request initialization.
     // - It may require specifying regional endpoints when creating the service client as shown in
     // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
     PredictionServiceSettings predictionServiceSettings =
         PredictionServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
     PredictionServiceClient predictionServiceClient =
         PredictionServiceClient.create(predictionServiceSettings);
     

    To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:

    
     // This snippet has been automatically generated and should be regarded as a code template only.
     // It will require modifications to work:
     // - It may require correct/in-range values for request initialization.
     // - It may require specifying regional endpoints when creating the service client as shown in
     // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
     PredictionServiceSettings predictionServiceSettings =
         PredictionServiceSettings.newHttpJsonBuilder().build();
     PredictionServiceClient predictionServiceClient =
         PredictionServiceClient.create(predictionServiceSettings);

Once the operation is done, [BatchPredictResult][google.cloud.automl.v1beta1.BatchPredictResult] is returned in the [response][google.longrunning.Operation.response] field. Available for following ML problems:
        • Image Classification
        • Image Object Detection
        • Video Classification
        • Video Object Tracking * Text Extraction
        • Tables

           BatchPredictInputConfig inputConfig = BatchPredictInputConfig.newBuilder().build();
           BatchPredictOutputConfig outputConfig = BatchPredictOutputConfig.newBuilder().build();
           Map<String, String> params = new HashMap<>();
           BatchPredictResult response =
               predictionServiceClient.batchPredictAsync(name, inputConfig, outputConfig, params).get();
         }
         
        Parameters:
        name - Required. Name of the model requested to serve the batch prediction.
        inputConfig - Required. The input configuration for batch prediction.
        outputConfig - Required. The Configuration specifying where output predictions should be written.
        params - Required. Additional domain-specific parameters for the predictions, any string must be up to 25000 characters long.
        • For Text Classification:

        `score_threshold` - (float) A value from 0.0 to 1.0. When the model makes predictions for a text snippet, it will only produce results that have at least this confidence score. The default is 0.5.

        • For Image Classification:

        `score_threshold` - (float) A value from 0.0 to 1.0. When the model makes predictions for an image, it will only produce results that have at least this confidence score. The default is 0.5.

        • For Image Object Detection:

        `score_threshold` - (float) When Model detects objects on the image, it will only produce bounding boxes which have at least this confidence score. Value in 0 to 1 range, default is 0.5. `max_bounding_box_count` - (int64) No more than this number of bounding boxes will be produced per image. Default is 100, the requested value may be limited by server.

        • For Video Classification :

        `score_threshold` - (float) A value from 0.0 to 1.0. When the model makes predictions for a video, it will only produce results that have at least this confidence score. The default is 0.5. `segment_classification` - (boolean) Set to true to request segment-level classification. AutoML Video Intelligence returns labels and their confidence scores for the entire segment of the video that user specified in the request configuration. The default is "true". `shot_classification` - (boolean) Set to true to request shot-level classification. AutoML Video Intelligence determines the boundaries for each camera shot in the entire segment of the video that user specified in the request configuration. AutoML Video Intelligence then returns labels and their confidence scores for each detected shot, along with the start and end time of the shot. WARNING: Model evaluation is not done for this classification type, the quality of it depends on training data, but there are no metrics provided to describe that quality. The default is "false". `1s_interval_classification` - (boolean) Set to true to request classification for a video at one-second intervals. AutoML Video Intelligence returns labels and their confidence scores for each second of the entire segment of the video that user specified in the request configuration. WARNING: Model evaluation is not done for this classification type, the quality of it depends on training data, but there are no metrics provided to describe that quality. The default is "false".

        • For Tables:

        feature_imp<span>ortan</span>ce - (boolean) Whether feature importance should be populated in the returned TablesAnnotations. The default is false.

        • For Video Object Tracking:

        `score_threshold` - (float) When Model detects objects on video frames, it will only produce bounding boxes which have at least this confidence score. Value in 0 to 1 range, default is 0.5. `max_bounding_box_count` - (int64) No more than this number of bounding boxes will be returned per frame. Default is 100, the requested value may be limited by server. `min_bounding_box_size` - (float) Only bounding boxes with shortest edge at least that long as a relative value of video frame size will be returned. Value in 0 to 1 range. Default is 0.
