AnnotationConsolidationLambdaArn

The Amazon Resource Name (ARN) of a Lambda function implements the logic for annotation consolidation.

For the built-in bounding box, image classification, semantic segmentation, and text classification task types, Amazon SageMaker Ground Truth provides the following Lambda functions:

  • Bounding box - Finds the most similar boxes from different workers based on the Jaccard index of the boxes.

    arn:aws:lambda:us-east-1:432418664414:function:ACS-BoundingBox

    arn:aws:lambda:us-east-2:266458841044:function:ACS-BoundingBox

    arn:aws:lambda:ca-central-1:918755190332:function:ACS-BoundingBox

  • Image classification - Uses a variant of the Expectation Maximization approach to estimate the true class of an image based on annotations from individual workers.

    arn:aws:lambda:us-east-1:432418664414:function:ACS-ImageMultiClass

    arn:aws:lambda:us-east-2:266458841044:function:ACS-ImageMultiClass

    arn:aws:lambda:ca-central-1:918755190332:function:ACS-ImageMultiClass

  • Semantic segmentation - Treats each pixel in an image as a multi-class classification and treats pixel annotations from workers as "votes" for the correct label.

    arn:aws:lambda:us-east-1:432418664414:function:ACS-SemanticSegmentation

  • Text classification - Uses a variant of the Expectation Maximization approach to estimate the true class of text based on annotations from individual workers.

    arn:aws:lambda:us-east-1:432418664414:function:ACS-TextMultiClass
