The Ultimate NanoBook to understand Deep Learning based Image Classifier

In today's world, we are making extensive use of images. Have you ever wonder how Facebook automatically detects faces in an image and then tells who is in the image like it did in the above figure. When I move the pointer near to one of the faces in the image, it automatically tells the name of the person and which is none other than Yann LeCun (who proposed the CNN Architecture). Have you ever used Snapchat? It automatically first detects your face and then accordingly apply the selected filter chosen by you. Something similar is also done by Apple's Face ID which will automatically unlock your phone when it founds your face in front of the device.
