Syntax

[BindServiceMethod(typeof(PredictionService), "BindService")]
public abstract class PredictionServiceBase

Methods

BatchPredict(BatchPredictRequest, ServerCallContext)

Perform a batch prediction. Unlike the online [Predict][google.cloud.automl.v1.PredictionService.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][google.longrunning.Operations.GetOperation] method. Once the operation is done, [BatchPredictResult][google.cloud.automl.v1.BatchPredictResult] is returned in the [response][google.longrunning.Operation.response] field. Available for following ML scenarios:

• AutoML Vision Classification
• AutoML Vision Object Detection
• AutoML Video Intelligence Classification
• AutoML Video Intelligence Object Tracking * AutoML Natural Language Classification
• AutoML Natural Language Entity Extraction
• AutoML Natural Language Sentiment Analysis
• AutoML Tables

Declaration

public virtual Task<Operation> BatchPredict(BatchPredictRequest request, ServerCallContext context)

Parameters

Type	Name	Description
BatchPredictRequest	request	The request received from the client.
ServerCallContext	context	The context of the server-side call handler being invoked.

Returns

Type	Description
System.Threading.Tasks.Task<Operation>	The response to send back to the client (wrapped by a task).

Predict(PredictRequest, ServerCallContext)

Perform an online prediction. The prediction result is directly returned in the response. Available for following ML scenarios, and their expected request payloads:

AutoML Vision Classification

• An image in .JPEG, .GIF or .PNG format, image_bytes up to 30MB.

AutoML Vision Object Detection

• An image in .JPEG, .GIF or .PNG format, image_bytes up to 30MB.

AutoML Natural Language Classification

• A TextSnippet up to 60,000 characters, UTF-8 encoded or a document in .PDF, .TIF or .TIFF format with size upto 2MB.

AutoML Natural Language Entity Extraction

• A TextSnippet up to 10,000 characters, UTF-8 NFC encoded or a document in .PDF, .TIF or .TIFF format with size upto 20MB.

AutoML Natural Language Sentiment Analysis

• A TextSnippet up to 60,000 characters, UTF-8 encoded or a document in .PDF, .TIF or .TIFF format with size upto 2MB.

AutoML Translation

• A TextSnippet up to 25,000 characters, UTF-8 encoded.

AutoML Tables

• A row with column values matching the columns of the model, up to 5MB. Not available for FORECASTING prediction_type.

Declaration
