Deep learning has recently received widespread attention. Using a model structure, this paper gives a summarization and analysis on deep learning by describing and reviewing the structure and characteristics of different models. The paper firstly introduces the concept and significance of deep learning, and then reviews four typical models:a convolutional neural network; deep belief networks; the deep Boltzmann machine; and an automatic stacking encoder. The paper then concludes by reviewing the applications of deep learning as regards speech processing, computer vision, natural language processing, medical science, and other aspects. Finally, the existing deep learning model is summarized and future challenges discussed
