Abstract:

Deep learning, which is a branch of machine learning, inaugurates new era in the development of neural
network. As a key component of deep structure, the deep auto-encoder is used to fulfill a task of transforming
learning and plays important role in both unsupervised learning and non-linear characters extraction. We firstly
introduced the origin of deep auto-encoder as well as its basic concept and principle, secondly, the construction
procedure, pre-training and fine-tune procedure of depth auto-encoders were generally introduced, meanwhile, a
comprehensive summarization of different kinds of DAE was made. At last, the direction of future work was proposed
based on an in-depth study of current DAE researches.

Key words: deep learning, deep auto-encoder(DAE), pre-train, fine-tune, neural network
