Final answer:
The correct answer is option c. machine learning.
Step-by-step explanation:
The new Amazon Go concept store is pioneering changes in physical retail, particularly through the use of machine learning and other advanced technologies. Unlike traditional retail checkouts, Amazon Go stores allow customers to simply walk out with their purchases without the need for a traditional checkout process.
The system automatically detects what products are taken off the shelves and charges the customer's Amazon account as they leave the store. This checkout-free shopping experience is made possible by a combination of technologies including computer vision, sensor fusion, and deep learning.
