Amazon Go

"Our checkout-free shopping experience is made possible by the same types of technologies used in self-driving cars: computer vision, sensor fusion, and deep learning."

Very interesting choice of comparison ha... I suppose this is Amazon trying to attract the tech crowd? It almost sounds satirical.

Not to downplay the tech -- this looks incredible.

From the rest of the text and the video, I have absolutely zero idea how they are using deep learning here. And let me not even mention that they've used the AI word in the video.

So, I highly doubt that attracting the tech crowd will work if they don't explain the damn thing about how they are using it.

Most people here are assuming there are RFID tags on every product.

But I think they are watching the shelves and visually identifying when a product leaves, what it was and who took it. And if they put it back on a different shelf, a different camera sees that and it is removed from the person's "shopping cart".

They are using their internal employees to train the AI or AI's (maybe one per section of shelf).

Imagine a Kellogg's employee assigned to watch each of their cereal boxes and make a list when someone takes one.

That's how I think they are using AI here. Hundreds of them in the store.
