Facebook uses a deep learning algorithm called Deep Face for face recognition.
Deep Face is a convolutional neural network (CNN) based algorithm that has been developed by Facebook's AI research team.
When you submit a photo to Facebook, Facebook employs the DeepFace feature, which uses deep learning algorithms for face verification and photo tag recommendations. The deep face uses neural network models to identify faces in digital pictures. The following are the steps that DeepFace takes to work:
Facebook primarily uses a deep learning algorithm called DeepFace for face recognition. DeepFace works by first detecting faces in images using a deep neural network, then normalizing and aligning them for consistency. Next, it employs a deep convolutional neural network to generate a numerical representation of each face, which is compared to a database of known faces to identify matches.
