Instagram is a platform where people share and post over a billion photos on a daily basis which include sceneries, mountains, pugs, Ferraris, brunches, and babies. Most people use this app for sharing photos because these photos are the memories of all of us. Instagram has become the number 1 image database all over the world over the last decade. Now the owner company of Instagram is trying to teach machines what are the importance of photos in our life and what photos show us, how these present the memories, and how what is inside the photos. Therefore, Facebook researchers are training a self-supervised algorithm using over a billion images on Instagram provided that this algorithm will not need human-labeled images to recognize what is inside the image.
