How Will AI Affect Our Life Recently, Google’s AlphaGo defeated Lee Sedol, the World Go Champion,4 to 1 in a five-game match. The machine’s sweeping victories have once again made AI (Artificial Intelligence) a hot topic. Some people welcome the progress and expect AI to benefit mankind in more fields. Some others fear that AI will eventually get out control. As we all know using AI is a sword with two blades which has both advantages and disadvantages. On the one hand, nowadays using AI robots in industry area is a common phenomenon. Using AI robots not only reduces the labor of workers, but also saves time and reduces cost. What is more,it can help people to produce high quality https://www.360docs.net/doc/1111471003.html,st but not least, AI robots are capable of many works which are dangerous to humans. In summary, we should make full use of AI robots. On the other hand, recently, there are several events which are AI robots hurt people. A robot killed a worker in 2015 in Germany which have once again arouse people’anxious about the security of using AI robot in production industry. So we should use AI robot with some protection measures. At the meanwhile, we must pay all attention to robot all the time when we use it. ALL in all, though AI robot has benefited us a lot, it also hurt us sometimes. I am in favor of using robotsin a scientific way.

人工智能论文——关于人工智能新突破(1)
人工智能导论 学院：工程学院 班级：软件工程0901 学号：A07090311 姓名：张丹
人工智能技术新突破 摘要：人工智能是当前科学技发展的一门前沿学科，同时也是一门新思想，新观念，新理论，新技术不断出现的新兴学科以及正在发展的学科。它是在计算机科学，控制论，信息论，神经心理学，哲学，语言学等多种学科研究的基础发展起来的，因此又可把它看作是一门综合性的边缘学科。它的出现及所取得的成就引起了人们的高度重视,并取得了很高的评价。有的人把它与空间技术，原子能技术一起并誉为20世纪的三大科学技术成就。 归纳逻辑是人工智能的逻辑基础。伴随人工智能研究的逐步深入，科学哲学、人工智能和归纳逻辑研究相互影响，出现了新的研究方向。以归纳逻辑为基础，多学科相互合作，可以建立新的机器学习系统或归纳学习系统。 关键词：人工智能发展；综合性边缘学科；归纳逻辑；机器学习；专家系统 一、智能计算机的发展 1．1人工智能概述 人工智能的进一步发展是基于归纳逻辑的基础之上的。近年来，人工智能与五代机的研究，所涉及的专家系统、机器学习、知识处理方面都必然运用归纳逻辑。一些研究者试图把归纳逻辑系统带入人工智能研究领域，从而找到一定的正确的方法来发展人工智能研究理论系统。 人工智能（Artificial Intelligence，简称AI）是计算机学科的一个分支，20 世纪70 年代以来，被称为世界三大尖端技术（空间技术、能源技术、人工智能）之一，也被认为是21 世纪三大尖端技术（基因工程、纳米科学、人工智能）之一。近三十年来，人工智能获得了迅速的发展，在很多学科领域都获得了广泛应用，并取得了丰硕的成果，在理论和实践上都已自成一个系统。 美国斯坦福大学人工智能研究中心的尼尔逊教授对人工智能下了这样一个定义：“人工智能是关于知识的学科———怎样表示知识以及怎样获得知识并使用知识的科学。”美国麻省理工学院的温斯顿教授认为：“人工智能就是研究如何使计算机去做过去只有人才能做的智能工作。”[2]普特南指出：“20 世纪早期逻辑领域出现的两位巨人哥德尔（Kurt Godel）和杰克斯·赫伯德（Jacgues Herbrand）对于人工智能研究作出了重要的贡献。”[3]1936 年，由图林提出的图林机器本来是个逻辑学的概念，并非为计算机的研制而提出，但图林机器理论与冯·诺意曼的程序内存思想为计算机科学与技术奠定了重要的理论基础。我国著名逻辑学者陈波教授认为，计算机科学和人工智能研究将是21 世纪早期逻辑学发展的主要动力源泉，并将由此决定21 世纪逻辑学的另一幅面貌[4]。人工智能所具有的独特的学科性质为逻辑学的研究和发展提出了更高的标准和挑战，逻辑学研究的对象、方法和意义都必将取得新的发展与突破。人工智能是用计算机来对人类思维过程和智能进行模拟（如学习、推理、思考、规划等）的学科，主要包括计算机实现智能的原理，制造类似于人脑智能的计算机，使计算机能实现更高层次的应用。人工智能几乎涉及自然科学和社会科学的所有学科，其研究范围非常广阔，包括问题求解、定理证明、专家系统、机器学习、智能控制、智能检索等。在人工智能的发展过程中，虽然对归纳的模拟以及智能化早就开始，但真正受到重视而且取

In 2016, Google’s AlphaGo defeated Lee Sedol, the World Go Champion, 4 to 1 in a five-game match. The machine’s sweeping victories have once again made AI（artificial intelligence）a hot topic. Some people fear that AI will eventually get out of control. To what extent do you agree or disagree with the opinion？Give reasons for your answer and include any relevant examples from your own knowledge or experience. A lphaGo’s great triumph over Lee Sedol once again draw s persons’ attention to artificial intelligence. And some people assert that AI will pose a threat to human existence if human lose control of it. In my opinion, it will be a long time before artificial intelligence has consciousness itself, not to mention defying human. But in the more distant future, we have reasons to believe that AI will have no distinction from human and disobey human’s orders. Artificial intelligence, in essence, is simulation of human ways of thinking. And its development deals with interdisciplinary of computer

人工智能概述
人工智能 人工智能是20世纪50年代中期兴起的一门新兴边缘科学，它既是计算机科学分支，又是计算机科学、控制论、信息论、语言学、神经生理学、心理学、数学、哲学等多种学科相互参透而发展起来的综合性学科。人工智能又称智能模拟，是用计算机系统模仿人类的感知、思维、推理等思维活动。它研究和应用的领域包括模拟识别、自然语言理解与生成、专家系统、自动程序设计、定理证明、联想与思维的机理、数据智能检索等。例如，用计算机模拟人脑的部分功能进行学习、推理、联想和决策；模拟医生给病人诊病的医疗诊断专家系统；机械手与机器人的研究和应用等。 一、人工智能发展史 50年代人工智能兴起，相继出现了一批显著的成果，如机器定理证明、跳棋程序、通用问题、求解程序LISP表处理语言等。但由于消解法推理能力的有限，以及机器翻译等的失败，使人工智能走入低谷。 60年代末到70年代，专家系统出现，使人工智能研究出现新高潮。并且1969年成立了国际人工智能联合会议。 80年代，随着第五代计算机的研制，人工智能得到了很大发展。日本1982年开始了“第五代计算机研制计划”，即“知识信息处理计算机系统KIPS”，其目的的是使逻辑推理达到数值运算那么快。 80年代末。神经网络飞速发展。1987年，美国召开第一次神经网络国际会议，宣告了这一科学的诞生。 90年代，人工智能出现新研究高潮由于网路技术特别是国际互联网技术的发展，人工智能开始由单个智能主体研究转向基于网络环境下的分布式人工智能研究。 二、人工智能的优越性
人工智能作为本世纪中叶新崛起的、综合性最强的新兴前沿科学，它涉及非常广泛的学科领域，它也可以同各门科技成果相结合，形成独立的综合性智能科学体系。在当代新的科学技术革命浪潮中，它愈来愈显示出强大的生命活力，具有无限广阔的发展前景。 1.人工智能是人类智能的必要补充。人工智能是随着科学技术的发展，在人们创造了各种复杂的机器设备，大大延伸和扩展了自己的手脚功能，迫切需要相应地延伸思维器官和放大智力功能的情况下，产生发展起来的。它是机器进化的结果，也是人类智能的物质化。它和人脑功能相互联系、相互促进，使人类的认识范围不断地向微观和宏观两极扩展，使人能通过间接方式达到对事物更深层次的本质的认识，使意识的内容得到极大丰富和增长。它已成为人类科学认识和社会实践活动不可缺少的技术“助手”。 中国科学院吴文俊在机器证明方面取得的成果，引起了国内外学术界的重视。他在这个领域内找到了一个快速判定过程，将几何问题表示为代数问题，于1977年证明了初等几何主要一类定理证明可以机械化。后又于1978年证明了初等微分几何中主要一类定理证明可以机械化，而且找到了实现机械化证明切实可行的方法。1980年，他只用了几十个小时就在一台微型机上得出一个不算简单的新定理。吴文俊的工作对人工智能有两点启发：一是强调在人工智能研究中从机器模拟人的求解目的转向讨论机器求解问题的方法;二是使人们重新注意定理证明技术在实际中的具体应用，特别是在实现信息检索机械化中的重要作用。 2.人工智能开辟了人类智力解放的道路。人工智能预示着第三次工业革命的到来，成为改变社会生活面 三、发展前景 3.1 人工智能的发展趋势 加强对人脑科学工业领域的应用，深入调研分析，掌握人工神经网络、机器人、新型人工智能产品等的发展和应用，整合现有资源，形成一些这方面的国家级或省级的技术中心和

There is no denying that their concerns is in my point of view,it is not a computer beats the human, but human defeated the human. First of all,the development of artificial intelligence will lead to unemployment in a large is the most direct intelligence can work more efficiently,and nobody can deny that they can work as cheaper , the most affected areas is areas of the economic law can be modeled,society may be last thing is people can be more and more lazy,people who is thinking would be only a violates the original intention of social development. However,artificial intelligence also have the positive side, they won't be tired and food and water become unnecessary,they work by electricity. But we should understand that the advantages should not be abused,if so,there will be an unpredictable ending. To make a long story short,artificial intelligence will become our "invisible assistant" rather than our competitors in within a period of time,we should cooperate fully with artificial intelligence,using it appropriately is the right way in my mind.
