Configure the PredictionService
Client

Public Instance Methods
Perform a batch prediction. Unlike the online {::Google::Cloud::AutoML::V1beta1::PredictionService::Client#predict Predict}, batch prediction result won't be immediately available in the response. Instead, a long running operation object is returned. User can poll the operation result via GetOperation method. Once the operation is done, {::Google::Cloud::AutoML::V1beta1::BatchPredictResult BatchPredictResult} is returned in the {::Google::Longrunning::Operation#response response} field. Available for following ML problems:
-
Image Classification
-
Image Object Detection
-
Video Classification
-
Video Object Tracking * Text Extraction
-
Tables
@overload batch_predict
(request, options = nil)
Pass arguments to `batch_predict` via a request object, either of type {::Google::Cloud::AutoML::V1beta1::BatchPredictRequest} or an equivalent Hash. @param request [::Google::Cloud::AutoML::V1beta1::BatchPredictRequest, ::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. @param options [::Gapic::CallOptions, ::Hash] Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.
@overload batch_predict
(name: nil, input_config: nil, output_config: nil, params: nil)
Pass arguments to `batch_predict` 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). @param name [::String] Required. Name of the model requested to serve the batch prediction. @param input_config [::Google::Cloud::AutoML::V1beta1::BatchPredictInputConfig, ::Hash] Required. The input configuration for batch prediction. @param output_config [::Google::Cloud::AutoML::V1beta1::BatchPredictOutputConfig, ::Hash] Required. The Configuration specifying where output predictions should be written. @param params [::Hash{::String => ::String}] 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.

Client
instance.
The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on {Client.configure}.
See {::Google::Cloud::AutoML::V1beta1::PredictionService::Client::Configuration} for a description of the configuration fields.
