Where Computers Defeat Humans, and Where They Can’t AlphaGo是怎么学会下围棋的

ALPHAGO, the artificial intelligence system built by the Google subsidiary DeepMind, has just defeated the human champion, Lee Se-dol, four games to one in the tournament of the strategy game of Go. Why does this matter? After all, computers surpassed humans in chess in 1997, when IBM’s Deep Blue beat Garry Kasparov. So why is AlphaGo’s victory significant?

由Google的子公司DeepMind创建的人工智能系统AlphaGo，刚刚在一场围棋比赛中以四比一的成绩战胜了人类冠军李世石(Lee Se-dol)。此事有何重大意义？毕竟在1997年IBM深蓝(Deep Blue)击败加里·卡斯帕罗夫(Garry Kasparov)后，电脑已经在国际象棋上超越了人类。为什么要对AlphaGo的胜利大惊小怪呢？

Like chess, Go is a hugely complex strategy game in which chance and luck play no role. Two players take turns placing white or black stones on a 19-by-19 grid; when stones are surrounded on all four sides by those of the other color they are removed from the board, and the player with more stones remaining at the game’s end wins.

和国际象棋一样，围棋也是一种高度复杂的策略性游戏，不可能靠巧合和运气取胜。两名棋手轮番将黑色或白色的棋子落在纵横19道线的网格棋盘上；一旦棋子的四面被另一色棋子包围，就要从棋盘上提走，最终在棋盘上留下棋子多的那一方获胜。

Unlike the case with chess, however, no human can explain how to play Go at the highest levels. The top players, it turns out, can’t fully access their own knowledge about how they’re able to perform so well. This self-ignorance is common to many human abilities, from driving a car in traffic to recognizing a face. This strange state of affairs was beautifully summarized by the philosopher and scientist Michael Polanyi, who said, “We know more than we can tell.” It’s a phenomenon that has come to be known as “Polanyi’s Paradox.”

然而和国际象棋不一样的是，没有人能解释顶尖水平的围棋是怎么下的。我们发现，顶级棋手本人也无法解释他们为什么下得那么好。人类的许多能力中存在这样的不自知，从在车流中驾驶汽车，到辨识一张面孔。对于这一怪象，哲学家、科学家迈克尔·波兰尼(Michael Polanyi)有精彩的概括，他说，“我们知道的，比我们可言说的多。”这种现象后来就被称为“波兰尼悖论”。

Polanyi’s Paradox hasn’t prevented us from using computers to accomplish complicated tasks, like processing payrolls, optimizing flight schedules, routing telephone calls and calculating taxes. But as anyone who’s written a traditional computer program can tell you, automating these activities has required painstaking precision to explain exactly what the computer is supposed to do.

波兰尼悖论并没有阻止我们用电脑完成一些复杂的工作，比如处理工资单、优化航班安排、转送电话信号和计算税单。然而，任何一个写过传统电脑程序的人都会告诉你，要想将这些事务自动化，必须极度缜密地向电脑解释要它做什么。

This approach to programming computers is severely limited; it can’t be used in the many domains, like Go, where we know more than we can tell, or other tasks like recognizing common objects in photos, translating between human languages and diagnosing diseases — all tasks where the rules-based approach to programming has failed badly over the years.

这样的电脑编程方式是有很大局限的；在很多领域无法应用，比如我们知道但不可言说的围棋，或者对照片中寻常物品的识别、人类语言间的转译和疾病的诊断等——多年来，基于规则的编程方法在这些事务上几无建树。Deep Blue achieved its superhuman performance almost by sheer computing power: It was fed millions of examples of chess games so it could sift among the possibilities to determine the optimal move. The problem is that there are many more possible Go games than there are atoms in the universe, so even the fastest computers can’t simulate a meaningful fraction of them. To make matters worse, it’s usually far from clear which possible moves to even start exploring.

“深蓝”几乎全凭强大的计算力实现了超人表现：它吸收了数百万份棋局实例，在可能选项中搜索最佳的走法。问题是围棋的可能走法比宇宙间的原子数还多，即使最快的电脑也只能模拟微不足道的一小部分。更糟的是，我们甚至说不清该从哪一步入手进行探索。

What changed? The AlphaGo victories vividly illustrate the power of a new approach in which instead of trying to program smart strategies into a computer, we instead build systems that can learn winning strategies almost entirely on their own, by seeing examples of successes and failures.

这次有什么不同？AlphaGo的胜利清晰地呈现了一种新方法的威力，这种方法并不是将聪明的策略编入电脑中，而是建造了一个能学习制胜策略的系统，系统在几乎完全自主的情况下，通过观看胜负实例来学习。

Since these systems don’t rely on human knowledge about the task at hand, they’re not limited by the

fact that we know more than we can tell.

由于这些系统并不依赖人类对这项工作的已有知识，即使我们知道的比可言说的更多，也不会对它构成限制。AlphaGo does use simulations and traditional search algorithms to help it decide on some moves, but its real breakthrough is its ability to overcome Polanyi’s Paradox. It did this by figuring out winning strategies for itself, both by example and from experience. The examples came from huge libraries of Go matches between top players amassed over the game’s 2,500-year history. To understand the strategies that led to victory in these games, the system made use of an approach known as deep learning, which has demonstrated remarkable abilities to tease out patterns and understand what’s important in large pools of information.

AlphaGo的确会在某几步棋中使用模拟和传统搜索算法来辅助决策，但它真正的突破在于它有能力克服“波兰尼悖论”。它能通过实例和经验自行得出制胜策略。这些实例来自2500年围棋历史积累下来的高人对局。为了理解这些棋局的制胜策略，系统采用了一种叫做“深度学习”的方法，经证明这种方法可以对规律进行有效梳理，在大量信息中认清哪些是重要的东西。

Learning in our brains is a process of forming and strengthening connections among neurons. Deep learning systems take an analogous approach, so much so that they used to be called “neural nets.”They set up billions of nodes and connections in software, use “training sets”of examples to strengthen connections among stimuli (a Go game in process) and responses (the next move), then expose the system to a new stimulus and see what its response is. AlphaGo also played millions of games against itself, using another technique called reinforcement learning to remember the moves and strategies that worked well.

在我们的大脑中，学习是神经元间形成和巩固关系的过程。深度学习系统采用的方法与此类似，以至于这种系统一度被称为“神经网络”。系统在软件中设置了数十亿个节点和连结，使用对弈实例组成的“训练集合”来强化刺激（一盘正在进行的围棋）和反应（下一步棋）的连结，然后让系统接收一次新的刺激，看看它的反应是什么。通过另一种叫做“强化学习”的技术，AlphaGo还和自己下了几百万盘棋，从而记住哪些走法和策略是有效的。Deep learning and reinforcement learning have both been around for a while, but until recently it was not at all clear how powerful they were, and how far they could be extended. In fact, it’s still not,

but applications are improving at a gallop, with no end in sight. And the applications are broad, including speech recognition, credit card fraud detection, and radiology and pathology. Machines can now recognize faces and drive cars, two of the examples that Polanyi himself noted as areas where we know more than we can tell.

深度学习和强化学习都是早已提出的技术，但我们直到近年才意识到它们的威力，以及它们能走多远。事实上我们还是不清楚，但对这些技术的应用正取得飞速的进步，而且看不到终点在哪里。它们的应用很广泛，包括语音识别、信用卡欺诈侦测、放射学和病理学。机器现在已经可以识别面孔、驾驶汽车，它们都曾被波兰尼本人归为知道但不可言说的领域。

We still have a long way to go, but the implications are profound. As when James Watt introduced his steam engine 240 years ago, technology-fueled changes will ripple throughout our economy in the years ahead, but there is no guarantee that everyone will benefit equally. Understanding and addressing the societal challenges brought on by rapid technological progress remain tasks that no machine can do for us.

我们还有很长的路要走，但潜能是十分可观的。就像240年前詹姆斯·瓦特(James Watt)首次推出蒸汽机，技术推动的变革在未来几年里将会波及我们的整个经济，但不能保证每个人都能从中得到同等的好处。快速的技术进步带来的社会挑战，依然是需要我们去理解和应对的，这方面不能指望机器。

考博英语翻译笔记

考博英语翻译笔记 倒装和分割结构 为了强调句子的某些部分，或是为了保持句子平衡，英语中常常使用倒装。大体说来，倒装可以分为主谓倒装和非主谓倒装。主谓倒装里又分为完全倒装和部分倒装。在翻译的时候，既可以按照主谓语的顺序翻译，也可以按照字面意思翻译。非主谓倒装只是将强调部分前置，以保持句子平衡或是起强调作用。翻译时可以采用顺序译法或是倒序译法。 1. For example, they do not compensate for social inequality, and thus do not tell how able an underprivileged youngster might have been had he grown up under more favorable circumstances. 分析：本句中had he grown up under more favorable circumstances 属于部分倒装。正常语序为：if he had grown up under more favorable circumstances 。在正式文体中，可以将虚拟条件句中的if 省略，并将助动词提前。 译文：例如，它们(指测试)并不弥补社会的不公，因此不能说明一个贫困青年，要是在比较有利的境况下长大，会有多大才干。 2. Nonstop waves of immigrants played a role, too and so did bigger crops of babies as yesterday's “baby boom ” generation reached its child-bearing years. 分析：该句中so did bigger crops of babies 属于语法倒装。用so 来代替前述肯定句谓语部分所说情况。 译文：不间断的移民浪潮也起了作用——而且随着昔日在“ 生育高峰期” 出生的 一代人达到生育年龄，婴儿的出生数量增加了，这同样起了作用。 3. Much as I have traveled, I have never seen anyone to equal her in thoroughness, whatever the job. 分析：该句的Much as I have traveled 是一个由as 引导的让步状语从句。相当于though I have traveled much ，但语气要比后者强。这种结构要求部分倒装。 译文：我虽然见多识广，但还从未见过比她细心的人，不管什么职业 4. Only when you have acquired a good knowledge of grammar can you write correctly. 分析：相信大家对这种结构都不陌生。Only 后加副词、介词、状语从句时要用部分倒装。但是要注意的是，如果only 修饰的不是状语，则不用倒装。 译文：只有很好地掌握了语法知识，写出来的东西才会正确。 5. Nowhere do 1980 census statistics dramatize more the American search for spacious living than in the Far West . 分析：当句首是否定副词或含有否定词的词语时，一般要部分倒装。 译文：1980 年哪里的人口普查统计资料也不如远西地区的更能生动地说明美国人对宽敞的生活环境的追求。 6. Hardly had he began to speak when the audience interrupted him. 分析：hardly…when的结构表示“冈U…就…”。含有这种结构的句子常将hardly 置于句首，而采用部分倒装的语序。此外，hardly分句中一般采用过去完成时，而when (或before )分句中使用过去时。还有，与hardly…when… 结构类似的用法还有barely (scarcely)…whe n … 译文：他刚开始讲，听众就打断了他的话。 7. To such length did she go in rehearsal that two actors walked out.

考博英语翻译策略

2012年考博考试英语翻译策略 无论是英汉翻译，还是汉英翻译，就翻译的过程而言，只有两个：一是对原文的理解，二是用译文来表达。 汉英翻译三步策略之一：定主语 1．翻译的单位 在翻译中，最小的翻译单位是什么？是篇章吗？是段落吗？是句子吗？是单词吗？甚至是音节吗？这是一个翻译理论家长期以来争论不休的一个话题。现在大多数翻译家、翻译理论家和翻译实践家都趋向于以篇章或者是整个问题为基本的翻译单位。但是，对于初学翻译的人来说，或者那些根本没有掌握翻译的人，要去应付一个翻译考试的时候，笔者认为，句子可能是最好的翻译单位。 什么是句子？或者具体说来，在汉英翻译中，要把汉语翻译成英语，究竟什么是英语的句子？ 柯林斯词典对英语句子的定义是这样的：A sentence is a group of words which，when they are written down，begin with a capital letter and end with a full stop，question mark or exclamation mark. Most sentences contain a subject and a verb.具体说来，英语的句子可以这样来定义：一个句子就是一组词，在书面语中，每一个句子首词的第一个字母大写，句末用句号、问号或者感叹号；大多数句子有主语和谓语。 根据英语句子的定义，我们可以清楚的知道，英语的句子中，大多数句子都有主语和谓语。那么汉英翻译，只要我们能把汉语转变成为准确通顺的英语，就需要搭建英语的主语和谓语等句式结构。而英语本身语法非常严谨，逻辑非常严密的特点，所以，在汉英翻译中，主语的确定和谓语的选择就是成功构建英语句式结构的关键，也是保证英语译文和汉语原文功能对等的关键。 2．确定汉语原文的主语为英语译文的主语 1）把汉语原文中的主语直接翻译成英语充当译文的主语，这是一种最简单、最可靠的对应方法，也是我们做汉英翻译“定主语”的时候首先应该考虑的方法。如： 例1．当前，国际形势正经历着自冷战结束以后最复杂、最深刻的变化。（中国

我的一个好朋友最近接受了白血病测试。她对我说，最令人痛苦的折磨就是苦苦等待测试结果的那一周时间。我朋友说，她可能会学着直面坏结果。但真正让人煎熬焦虑的是那种茫然的感觉。 孟克(Edvard Munch)的名画《呐喊》哈佛大学心理学家吉尔伯特(Daniel Gilbert)不久前在《纽约时报》(New York Times)的专栏中写道，不知道要发生什么坏事比知道什么坏事要发生的感觉更糟。我们大多数人之所以会夜不能寐、抽烟发泄，并不是因为道琼斯指数要再跌1000点，而是因为我们不知道道指会不会下跌──不确定的感觉比不确定的事情本身更折磨人。【英文】 A close friend of mine recently underwent tests for leukemia. The most agonizing part of the ordeal, she said, was the week-long wait for the test results. A bad outcome she could learn to cope with, my friend said. It was the not knowing, the uncertainty, that was so difficult. 'People feel worse when something bad might occur than when something bad will occur,' wrote Harvard psychologist Daniel Gilbert in a recent New York Times op-ed. 'Most of us aren't losing sleep and sucking down Marlboros because the Dow is going to fall another thousand points, but because we don't know whether it will fall or not ─ and human beings find uncertainty more painful than the things they're uncertain about.'

2013年 同济大学 考博英语翻译原文

同济大学2013年考博英语翻译 I am far from thinking, that all those, who have depreciated our species, have been enemies to virtue, and have exposed the frailties of their fellow creatures with any bad intention. On the contrary, I am sensible that a delicate sense of morals, especially when attended with a splenetic temper, is apt to give a man a disgust of the world, and to make him consider the common course of human affairs with too much indignation. I must, however, be of opinion, that the sentiments of those,who are inclined to think favourably of mankind, are more advantageous to virtue, than the contrary principles, which give us a mean opinion of our nature. When a man is prepossessed with a high notion of his rank and character in the creation, he will naturally endeavour to act up to it, and will scorn to do a base or vicious action, which might sink him below that figure which he makes in his own imagination. Accordingly we find, that all our polite and fashionable moralists insist upon this topic, and endeavour to represent vice as unworthy of man, as well as odious in itself. We find few disputes, that are not founded on some ambiguity in the expression; and I am persuaded, that the present dispute, concerning the dignity or meanness of human nature, is not more exempt from it than any other. It may, therefore, be worth while to consider, what is real, and what is only verbal, in this controversy.

北京师范大学考博英语翻译试题及其解析Investigators of monkey’s social behavior have always been struck by monkeys’aggressive potential and the consequent need for social control of their aggressive behavior.Studies directed at describing aggressive behavior and the situations that elicit it,as well as the social mechanisms that control it,were therefore among the first investigations of monkeys’social behavior. Investigators initially believed that monkeys would compete for any resource in the environment:hungry monkeys would fight over food, thirsty monkeys would fight over water,and,in general,at time more than one monkey in a group sought the same incentive simultaneously, a dispute would result and would be resolved through some form of aggression.However,the motivating force of competition for Geng duo yuan xiao wan zheng kao bo ying yu zhen ti ji qi jie xi qing lian xi quan guo mian fei zi xun dian hua:si ling ling liu liu ba liu jiu qi ba,huo jia zi xun qq:qi qi er liu qi ba wu san qi incentives began to be doubted when experiments like Southwick’s on the reduction of space or the withholding of food failed to produce more than temporary increases in intragroup aggression.Indeed,food deprivation not only failed to increase aggression but in some cases actually resulted in decreased frequencies of aggression. Studies of animals in the wild under conditions of extreme food deprivation likewise revealed that starving monkeys devoted almost all available energy to foraging,with little energy remaining for aggressive interaction.Furthermore,accumulating evidence from

AlphaGo是怎么学会下围棋的 2017北京地大考博群 221616188 Where Computers Defeat Humans, and Where They Can’t AlphaGo是怎么学会下围棋的 ALPHAGO, the artificial intelligence system built by the Google subsidiary DeepMind, has just defeated the human champion, Lee Se-dol, four games to one in the tournament of the strategy game of Go. Why does this matter? After all, computers surpassed humans in chess in 1997, when IBM’s Deep Blue beat Garry Kasparov. So why is AlphaGo’s victory significant? 由Google的子公司DeepMind创建的人工智能系统AlphaGo，刚刚在一场围棋比赛中以四比一的成绩战胜了人类冠军李世石(Lee Se-dol)。此事有何重大意义？毕竟在1997年IBM深蓝(Deep Blue)击败加里·卡斯帕罗夫(Garry Kasparov)后，电脑已经在国际象棋上超越了人类。为什么要对AlphaGo的胜利大惊小怪呢？ Like chess, Go is a hugely complex strategy game in which chance and luck play no role. Two players take turns placing white or black stones on a 19-by-19 grid; when stones are surrounded on all four sides by those of the other color they are removed from the board, and the player with more stones remaining at the game’s end wins. 和国际象棋一样，围棋也是一种高度复杂的策略性游戏，不可能靠巧合和运气取胜。两名棋手轮番将黑色或白色的棋子落在纵横19道线的网格棋盘上；一旦棋子的四面被另一色棋子包围，就要从棋盘上提走，最终在棋盘上留下棋子多的那一方获胜。 Unlike the case with chess, however, no human can explain how to play Go at the highest levels. The top players, it turns out, can’t fully access their own knowledge about how they’re able to perform so well. This self-ignorance is common to many human abilities, from driving a car in traffic to recognizing a face. This strange state of affairs was beautifully summarized by the philosopher and scientist Michael Polanyi, who said, “We know more than we can tell.” It’s a phenomenon that has come to be known as “Polanyi’s Paradox.” 然而和国际象棋不一样的是，没有人能解释顶尖水平的围棋是怎么下的。我们发现，顶级棋手本人也无法解释他们为什么下得那么好。人类的许多能力中存在这样的不自知，从在车流中驾驶汽车，到辨识一张面孔。对于这一怪象，哲学家、科学家迈克尔·波兰尼(Michael Polanyi)有精彩的概括，他说，“我们知道的，比我们可言说的多。”这种现象后来就被称为“波兰尼悖论”。 Polanyi’s Paradox hasn’t prevented us from using computers to accomplish complicated tasks, like processing payrolls, optimizing flight schedules, routing telephone calls and calculating taxes. But as anyone who’s written a traditional computer program can tell you, automating these activities has required painstaking precision to explain exactly what the computer is supposed to do. 波兰尼悖论并没有阻止我们用电脑完成一些复杂的工作，比如处理工资单、优化航班安排、转送电话信号和计算税单。然而，任何一个写过传统电脑程序的人都会告诉你，要想将这些事务自动化，必须极度缜密地向电脑解释要它做什么。 This approach to programming computers is severely limited; it can’t be used in the many domains, like Go, where we know more than we can tell, or other tasks like recognizing common objects in photos, translating between human languages and diagnosing diseases — all tasks where the rules-based approach to programming has failed badly over the years. 这样的电脑编程方式是有很大局限的；在很多领域无法应用，比如我们知道但不可言说的围棋，或者对照片中寻常物品的识别、人类语言间的转译和疾病的诊断等——多年来，基于规则的编程方法在这些事务上几无建树。Deep Blue achieved its superhuman performance almost by sheer computing power: It was fed millions of examples of chess games so it could sift among the possibilities to determine the optimal move. The problem is that there are many more possible Go games than there are atoms in the universe, so even the fastest computers can’t simulate a meaningful fraction of them. To make matters worse, it’s usually far from clear which possible moves to even start exploring. “深蓝”几乎全凭强大的计算力实现了超人表现：它吸收了数百万份棋局实例，在可能选项中搜索最佳的走法。问题是围棋的可能走法比宇宙间的原子数还多，即使最快的电脑也只能模拟微不足道的一小部分。更糟的是，我们甚至说不清该从哪一步入手进行探索。 What changed? The AlphaGo victories vividly illustrate the power of a new approach in which instead of trying to program smart strategies into a computer, we instead build systems that can learn winning strategies almost entirely on their own, by seeing examples of successes and failures. 这次有什么不同？AlphaGo的胜利清晰地呈现了一种新方法的威力，这种方法并不是将聪明的策略编入电脑中，而是建造了一个能学习制胜策略的系统，系统在几乎完全自主的情况下，通过观看胜负实例来学习。 Since these systems don’t rely on human knowledge about the task at hand, they’re not limited by the
