12 Artificial Intelligence Terms You Need to Know - InformationWeek

Just like machine learning is a subset of artificial intelligence, deep learning is a subset of machine learning. Going back to that workshop definition, deep learning is the part of machine learning that focuses on forming "abstractions and concepts." Deep learning systems ingest large quantities of data and generalize categories and features related to that data through supervised or unsupervised learning. To understand how this works, consider the problem of teaching a computer to distinguish pictures of cats from pictures of dogs. Programmers could try to come up with a set of rules that explains exactly what a cat is and exactly what a dog is, but even though humans can easily distinguish a cat from a dog, it's really hard to explain that difference using algorithms that a computer can understand. However, a deep learning system can analyze a whole bunch of pictures of animals and come to its own generalizations about what distinguishes a cat from a dog.
