What is Deep Learning, and what is it based on?
Reviewed by Jason Burns, Editorial Steward · Last updated
Deep learning is a branch of machine learning that uses artificial neural networks with many layers to learn hierarchical representations of data, and it is based on backpropagation, gradient-based optimization, and large-scale training. As Yann LeCun, Yoshua Bengio & Geoffrey Hinton, put it on the record: "Deep learning allows computational models that are composed of multiple processing layers to learn representations of data with multiple levels of abstraction."
