Creating Artificial Intelligence (AI) comparable to human Intelligence is an old dream which we name it as AI problem. Many scientists have tried to solve it. The traditional method is Rule Based, which some rules with the other techniques such as search methods are used to solve the problems. Although it could some problems, however many challenges still remain unsolved. The other important technique is machine learning method. In this approach, the system based on the training data or examples, tries to learn and sole similar tasks or queries. The success of this method was also limited, until recent years, where a new kind of learning, named deep learning was introduced. The success of this method is so significant that somebody named it as a revolution in AI, and now, people are much closer to solve of AI problem. Simply Deep learning is a multi-layer system, where each layer extracts a level of abstraction of the input data. in Continue of this presentation, more detail and explanation of deep learning and its applications and success are presented.
