Is Deep Learning Really a Good Solution?

Deep learning is something that's more easily usable across different industries and different projects. It turns out that one of the keys to mastering deep learning is to find a way to describe the work you want it to do in terms of mapping from an input domain to an output domain. The first step would just be to go through all the pictures and find where the faces are. You'd want to figure out who that is actually a picture of. Where the first deep learning task was detecting, you were just detecting where the faces were. Second deep learning task is one of classification, where you're trying to tell the difference between lots of different faces.
