Instead, I believe FaceID is powered by a siamese-like convolutional neural network that is trained “…ne”, i.e. in their laboratories, and then ship it already trained and ready to use in their phones. Instead, I believe FaceID is powered by a siamese-like convolutional neural network that is trained “offline” by Apple to map faces into a low-dimensional latent space shaped to maximize distances between faces of different people, using a contrastive loss. What happens is that you get an architecture capable of doing one shot learning, as they very brief…
