Gportrait is an online platform that uses deep learning to discover the relationship between genes and phenotypes. It can simulate human faces with 2D pictures and 3D structure according to genetic data. It can also generate faces taking into consideration postnatal factors such as weight and age. Gportrait can predict a child’s face for parents and even assist in the search for children gone missing for years. Moreover, from DNA left behind by crime suspects, Gportrait can predict their faces to help to catch them.
