What is Deep Learning? - OpenMind

Deep learning is an emerging topic in artificial intelligence (AI). A subcategory of machine learning, deep learning deals with the use of neural networks to improve things like speech recognition, computer vision, and natural language processing. In the last few years, deep learning has helped forge advances in areas as diverse as object perception, machine translation, and voice recognition-all research topics that have long been difficult for AI researchers to crack. In information technology, a neural network is a system of programs and data structures that approximates the operation of the human brain. A neural network usually involves a large number of processors operating in parallel, each with its own small sphere of knowledge and access to data in its local memory.
