1 definition of artificial intelligence

Artificial intelligence (AI) is an interdisciplinary subject which combines computer science, physiology and philosophy. ? Artificial intelligence? This word was first put forward at the Dartmouth Society organized by the American Computer Association in 1956. Since then, researchers have developed many theories and principles, and the concept of artificial intelligence has also expanded. Due to the uncertainty of the concept of intelligence, there has never been a unified standard for the concept of artificial intelligence. Professor Nelson, the famous artificial intelligence research center of Stanford University in the United States, has given such a definition to artificial intelligence? Artificial intelligence is a subject about knowledge ―― how to express knowledge and how to acquire and use it. ? Professor Winston of MIT thinks? Artificial intelligence is to study how to make computers do intelligent work that only people can do in the past. ? Tong Tianxiang is in "From? Man-machine war? To define artificial intelligence in man-machine life: Although today's machines can't think, they don't? Intuitive equation? However, the way people deal with problems can be programmed into intelligent programs. Even machines that can't think have intelligence, so that machines can do things that require human intelligence, that is, artificial intelligence. ? These definitions basically reflect the basic ideas and contents of artificial intelligence. That is, artificial intelligence is the basic theory, method and technology to study the law of human intelligence activities, construct an artificial system with certain intelligence, and study how to make computers do the work that needed human intelligence in the past, that is, how to use computer software and hardware to simulate some intelligent behaviors of human beings.

2 Application fields of artificial intelligence

2.2 Application of artificial intelligence expert system in engineering field

Application of artificial intelligence expert system in medicine. MYCIN expert system is the first foreign expert system that applies artificial intelligence to medical diagnosis. 1982, Miller of the University of Pittsburgh published the research results of the famous physician 2I computer-aided diagnosis system as a doctor's consultation. 1977 was improved to internist 2iii, which became CAU-CEUS, 19 1 DEX-PLAIN developed by Barnett of Harvard Medical School in the United States. The development of expert systems based on artificial intelligence in China began in the late 1970s, but it developed rapidly. Was the early one developed by Beijing College of Traditional Chinese Medicine? GuanYouBo hepatitis medical expert system? It is a program that simulates the diagnosis and treatment of liver diseases by Dr. Guan Youbo, a famous old Chinese doctor. In the early 1980s, Fujian College of Traditional Chinese Medicine and Fujian Computer Center developed a computer diagnosis and treatment system for Lin Rugao's bone injury. Other institutions of higher learning, such as Xiamen University, Chongqing University, Henan Medical University and Changchun University, have developed medical computer expert systems based on artificial intelligence, which have been successfully applied in clinic.

Application of artificial intelligence in mining industry. The first artificial intelligence expert system related to mining industry is PROSPECTOR, an expert system for mineral exploration and evaluation of Stanford International Research Institute, which is used for exploration and evaluation, regional resource evaluation and drilling well location selection. Since 1980s, Pittsburgh Research Center of American Bureau of Mining has cooperated with other units to develop expert systems for floor heave prevention, gas control and coal dust control in coal mines. Virginia Tech and State University have developed an expert system Consim, which is used to simulate mining, loading, transportation, roof anchoring and equipment inspection in the process of continuous mining. The University of Alaska has compiled an expert system for selecting mining methods for underground coal mines.

2.3 Application of artificial intelligence in technical research

Application of artificial intelligence in ultrasonic nondestructive testing. In the field of ultrasonic nondestructive testing and NDE, expert system method is widely used to judge and classify the nature, shape and size of defects in ultrasonic damage. Experts have built a bridge between traditional ultrasonic nondestructive testing and intelligent ultrasonic nondestructive testing, which can turn ordinary flaw detectors into skilled flaw detectors. An experienced expert. Therefore, this intelligent ultrasonic nondestructive testing has great practical application value.

Application of artificial intelligence in electronic technology. Shen Xianqing thinks that artificial intelligence and simulation technology can be combined, and the hardware circuit of single chip microcomputer can be used as the knowledge source of expert system, and an expert system of single chip microcomputer hardware configuration can be established to diagnose faults, so as to improve the ability of error correction. Artificial intelligence technology has also been introduced into the field of computer networks. The common technology of computer network security management is firewall technology, and the core part of firewall is intrusion detection technology. With the rapid development of the network, various intrusion means emerge one after another, and the traditional prevention means alone can't meet the needs of reality. The application of artificial intelligence technology in the field of network security management has greatly improved its security. Ma Xiurong and others introduced how to apply artificial intelligence technology to computer network security management in the article "Brief Introduction to the Application of Artificial Intelligence Technology in Network Security Management", which played a good role in security prevention.

3 the development direction of artificial intelligence

3. 1 Development Status of Artificial Intelligence

Present situation of foreign development. At present, AI technology is developing rapidly in the United States, Europe and Japan. IBM, which is very active in the field of AI technology. Have you gone to Lawrence, California? Livermore national laboratory has built a computer that claims to have one thousandth of the intelligence of the human brain? ASCII white Computers, as well as more powerful new supercomputers, are being developed-Bruegen? According to its research director Paul? Horn said that it is expected? Blue cowboy? The level of intelligence will be roughly equal to that of the human brain. The artificial intelligence laboratory of MIT is carrying out a new project code-named cog. Cog project aims to give robots human behavior. One project of this experiment is to let the robot capture eye movements and facial expressions, another project is to let the robot capture things passing by, and another project is to let the robot learn to listen to the rhythm of music and play on the drum. Because artificial intelligence has broad development prospects, the huge development market is favored by countries and companies. In addition to IBM and other companies continue to invest heavily in AI technology to ensure its leading position, other companies also maintain a certain proportion of investment in the branch research of artificial intelligence. Microsoft President Bill? Gates delivered a keynote speech at the AI (Artificial Intelligence) International Conference held in Washington, USA, saying that Microsoft Research Institute is currently working on the research of basic and applied technologies of AI, including self-determination, expression of knowledge and information, information retrieval, mechanical learning, data acquisition, natural language, voice handwriting recognition, etc.

The application of artificial intelligence in network information retrieval mainly shows as follows: ① How to use computer software and hardware systems to imitate, extend and expand the theories, methods and technologies of human intelligence, including machine perception, machine thinking and machine behavior, that is, the process of knowledge acquisition, knowledge processing and knowledge utilization. (2) Because network knowledge information not only contains regular knowledge such as general principles and concepts, but also contains a lot of empirical knowledge, which inevitably brings uncertainties such as fuzziness, randomness and unreliability, it is necessary to use the research results of artificial intelligence for reasoning.

Intrusion detection method based on expert system. Expert system in intrusion detection is a set of inference rules obtained by network security experts after analyzing suspicious behaviors. Rule-based expert system can expand and modify rules with the accumulation of experience under the guidance of experts. Compared with statistical methods, expert system is less dependent on historical records, so it has strong adaptability and can flexibly adapt to Guangpu's security strategy and detection requirements. This is a main direction of the development of artificial intelligence.

Application of artificial intelligence in robots. Robot soccer system is a hot spot in the research of artificial intelligence system at present, and its high-tech and entertaining characteristics have attracted the interest of a large number of scholars at home and abroad.
