The largest ever study of facial-recognition data shows how much the rise of deep learning has fueled a loss of privacy.

But according to researchers, including LeCun, deep learning can advance the state of the art---just as it has vastly improved technologies such as image recognition and speech recognition.

Deep learning is a topic that is making big waves at the moment. It is basically a branch of machine learning (another hot topic) that uses algorithms to e.g. recognize objects and understand ...
