Deep learning is a hot topic in the machine-learning world today. We could say that there’s a deep-learning revolution going on. Deep learning is a general term denoting a family of machine-learning methods characterized by the use of multiple processing layers of nonlinear transformations. These layers are almost universally implemented as neural networks.

Although the core principles aren’t new, a lack of computing power and efficient ...
