My name is Sean (Xiang) Ma, and I work on physical retail technologies at Amazon that enable our customers to shop better.

I’m also currently the Head of Research for Amazon Dash Cart, which is a new product that we’ve just introduced. I’m excited to talk to you about what we’ve been doing and how computer vision and AI have been changing our customers' shopping experience.

I’ve seen the emergence of lots of new applications in recent years. The advancement of transformer neural networks has greatly improved real-world applications, and that's very exciting.
