人工智能

ABSTRACT In recent years data mining gets more and more attention and becomes one of the hottest spot in IT research field. Researchers from various fields show great enthusiasm for the subjects in data mining and are willing to devote themselves to the new field because data mining syncretizes artificial intelligence, statistics, database, and machine study. At the beginning of this new century, it is a large-scale amalgamation of subjects.

短短的几年时间，数据挖掘风靡全球，成为IT业近年来非常热门和前沿的研究方向之一，由于数据挖掘融合了人工智能、统计学、数据库、机器学习等各个领域的理论与技术，使得不同学科领域的学者对DM的研究表现出了前所未有的热情和参与精神，在世纪交替的特殊时期，这是又一轮规模空前的学科大融合。

At the present day, computer is becoming universalizing, and technology of Expert System , Artificial Intelligent and-other science is developing and coming to maturity, which provide well material foundation and technological support for solving problem of collision prevention.

当前，计算机在各类船舶中的普及与应用，专家系统技术及人工智能领域内的其它技术的发展、成熟，为解决避碰这一难题提供了良好的物质基础与技术支持。

To avoid the collision accidents of ships at sea, with the universalizing and application of computer, and the development and maturity of the technology of Expert System and Artificial Intelligent, this paper developed an intelligent collision avoidance expert system for navigation. The main research work centers on several aspects, which will be represented as below:By the navigation rules" understanding and analyzing, and by the navigation experience and navigation samples" collecting and trimming, we put forth and build a multi-unit and layering KB systematic structure, and implement the KBM. According to features of different knowledge, we adopt multifarious KR, such as: frame KR, production rule KR, procedure KR. We also build a multi-inference system, which based on analog inference, forward illation inference, conversion inference and meta-rule inference. At the same time, we develop each reasoning algorithm. For some problems in collision avoidance region during the building of the expert system, we put forth and build a set of models to solve them using neural network technology.
