Hi, I’m Suchen Wang.

I'm a Senior Applied Scientist at Amazon AWS, working on Just Walk Out (JWO) autonomous retail technology. I received my Ph.D. from Nanyang Technological University (NTU), Singapore in 2022, advised by Prof. Junsong Yuan and Prof. Yap-Peng Tan. My research interests span action recognition, object detection, human–object interaction (HOI), large-scale video understanding, and visual reasoning.

Just Walk Out (JWO) is Amazon’s checkout-free retail technology that uses machine learning and computer vision to create a checkout-free shopping experience. This system allows shoppers to enter a store, take the items they want, and simply walk out without having to use a traditional checkout. The total for their items is automatically charged to their payment method after they exit. I'm working at the shopping team with mission of generating accurate receipts. As shoppers pick up items, overhead cameras and the shopping model running behind will add the picked products to their virtual cart. Our shopping model continuously recognizes shopping activities to maintain individual virtual cart for each shopper. Since joining Amazon, I'm contributing to JWO’s large-scale perception systems. We have built and developed visual reasoning models that power 300+ JWO stores across the United States, United Kingdom, Canada, Australia, and France, etc.
