AWS Certified Machine Learning – Specialty — Question 214

A sports analytics company is providing services at a marathon. Each runner in the marathon will have their race ID printed as text on the front of their shirt. The company needs to extract race IDs from images of the runners.

Which solution will meet these requirements with the LEAST operational overhead?

Answer options

• A. Use Amazon Rekognition.
• B. Use a custom convolutional neural network (CNN).
• C. Use the Amazon SageMaker Object Detection algorithm.
• D. Use Amazon Lookout for Vision.

Correct answer: A

Explanation

Amazon Rekognition is a fully managed service that can quickly and accurately extract text from images with minimal setup, making it ideal for this task with low operational overhead. In contrast, creating a custom CNN or using more complex algorithms like Amazon SageMaker Object Detection requires more time, resources, and maintenance, increasing operational overhead unnecessarily.
