What is deep learning?

Most of the time when we are talking about AI, we are thinking about a very specific form of AI called machine learning. Machine learning systems use a range of mathematical processes to learn procedures and perform tasks automatically. You don't need to exactly mimic human intelligence in order to create a system that appears intelligent. Instead, you can model a range of problem solving architectures that are comparatively simple to understand. One type of machine learning approach that is very important at the moment is deep learning.
