Which of the following is a service that facilitates human review in ML predictions?

Amazon Augmented AI (Amazon A2I) is a service designed specifically to facilitate human review in machine learning predictions. This service allows organizations to integrate human oversight into their machine learning workflows.

When ML models generate predictions, there may be instances where the outcomes require further validation or review by human experts, especially in cases where the stakes are high, such as in healthcare or financial applications. Amazon A2I provides a simple way to implement a human review process, enabling businesses to create workflows that determine when human input is needed, thereby improving the overall accuracy and trustworthiness of the ML predictions.

The other services listed, while powerful in their respective domains, serve different primary functions. For instance, Amazon Comprehend focuses on natural language processing tasks, such as sentiment analysis and entity recognition, while Amazon Rekognition specializes in image and video analysis. Amazon SageMaker is a comprehensive platform for building, training, and deploying machine learning models but does not inherently provide a mechanism for human review of predictions. Thus, Amazon A2I is uniquely suited for the task of incorporating human oversight into machine learning predictions.
