AI and machine learning powers three popular Amazon products: Alexa, the Amazon Go Store, and the Amazon recommendation engine. The Amazon Echo, which features AI bot Alexa, has been one of the company's most popular forays into machine learning.
How does Amazon use Machine Learning?

The e-commerce giant uses AI behind the scenes to grow its marketplace:
- By aggregating and analyzing purchasing data on products using machine learning, Amazon can more accurately forecast demand.
- It also uses machine learning to analyze purchasing patterns and identify fraudulent purchases. Paypal uses the same approach, resulting in a .32% revenue fraud rate, compared with the 1.32% industry average.
- In addition, Amazon utilizes browsing and purchasing data to provide tailored product recommendations and promotions.
Is Alexa AI or ML?
Alexa is neither an AI nor a product of ML - yet. It's speech recognition, natural language processing, Human voice generation. All cool stuff in the hand of everybody.

If you are developing alexa then you can easily see that one just needs to provide questions and answers respectively. Alexa just searches for given query, if found then converts the answer from text to speech.
DANCE OF THE ROBOTS
Deep inside Amazon’s 855,000-square-foot fulfillment center in Kent, Washington, 18 miles south of Seattle, a bunch of orange Amazon robots are doing a dance. Balanced on top of each of the orange machines is a yellow pod with nine rows of product-packed shelves on each of four sides. Powered by AI, each of the robots automatically sprang into action when someone somewhere in the Pacific Northwest purchased something on Amazon.com, and each is now autonomously maneuvering its way around the others in a bid to get to a station at the edge of the fenced-off robotic field where a worker will pluck the item in question and put it on a conveyor belt toward another worker who will box it up.
GRAB AND GO
Given that the heart of the new fulfillment center system involves using cameras and AI software to detect someone holding an item and placing it on a shelf, you might think that the same technology is in use at Amazon Go, Amazon’s automated grocery stores that allow customers to walk in, grab what they want, and simply walk out the door, with everything being charged to their account automatically.
As of now, there are only four Amazon Go outlets–three in Seattle and another in Chicago, with more on the way. But they are able to handle a steady flow of customers who can scan their phone upon entry, shop as much or as little as they want, pick thing off of shelves and put them back, and accurately track what they end up leaving with, regardless of numerous potential pitfalls along the way.
