Service from afarДистанционный сервисABB’s Remote Service concept is revolutionizing the robotics industryРазработанная АББ концепция дистанционного обслуживания Remote Service революционизирует робототехникуABB robots are found in industrial applications everywhere – lifting, packing, grinding and welding, to name a few. Robust and tireless, they work around the clock and are critical to a company’s productivity. Thus, keeping these robots in top shape is essential – any failure can lead to serious output consequences. But what happens when a robot malfunctions?Роботы АББ используются во всех отраслях промышленности для перемещения грузов, упаковки, шлифовки, сварки – всего и не перечислить. Надежные и неутомимые работники, способные трудиться день и ночь, они представляют большую ценность для владельца. Поэтому очень важно поддерживать их в надлежащей состоянии, ведь любой отказ может иметь серьезные последствия. Но что делать, если робот все-таки сломался?ABB’s new Remote Service concept holds the answer: This approach enables a malfunctioning robot to alarm for help itself. An ABB service engineer then receives whole diagnostic information via wireless technology, analyzes the data on a Web site and responds with support in just minutes. This unique service is paying off for customers and ABB alike, and in the process is revolutionizing service thinking.Ответом на этот вопрос стала новая концепция Remote Service от АББ, согласно которой неисправный робот сам просит о помощи. C помощью беспроводной технологии специалист сервисной службы АББ получает всю необходимую диагностическую информацию, анализирует данные на web-сайте и через считанные минуты выдает рекомендации по устранению отказа. Эта уникальная возможность одинаково ценна как для заказчиков, так и для самой компании АББ. В перспективе она способна в корне изменить весь подход к организации технического обслуживания.Every minute of production downtime can have financially disastrous consequences for a company. Traditional reactive service is no longer sufficient since on-site service engineer visits also demand great amounts of time and money. Thus, companies not only require faster help from the service organization when needed but they also want to avoid disturbances in production.Каждая минута простоя производства может привести к губительным финансовым последствиям. Традиционная организация сервиса, предусматривающая ликвидацию возникающих неисправностей, становится все менее эффективной, поскольку вызов сервисного инженера на место эксплуатации робота сопряжен с большими затратами времени и денег. Предприятия требуют от сервисной организации не только более быстрого оказания помощи, но и предотвращения возможных сбоев производства.In 2006, ABB developed a new approach to better meet customer’s expectations: Using the latest technologies to reach the robots at customer sites around the world, ABB could support them remotely in just minutes, thereby reducing the need for site visits. Thus the new Remote Service concept was quickly brought to fruition and was launched in mid-2007. Statistics show that by using the system the majority of production stoppages can be avoided.В 2006 г. компания АББ разработала новый подход к удовлетворению ожиданий своих заказчиков. Использование современных технологий позволяет специалистам АББ получать информацию от роботов из любой точки мира и в считанные минуты оказывать помощь дистанционно, в результате чего сокращается количество выездов на место установки. Запущенная в середине 2007 г. концепция Remote Service быстро себя оправдала. Статистика показывает, что её применение позволило предотвратить большое число остановок производства.Reactive maintenance The hardware that makes ABB Remote Service possible consists of a communication unit, which has a function similar to that of an airplane’s so-called black box 1. This “service box” is connected to the robot’s control system and can read and transmit diagnostic information. The unit not only reads critical diagnostic information that enables immediate support in the event of a failure, but also makes it possible to monitor and analyze the robot’s condition, thereby proactively detecting the need for maintenance.Устранение возникающих неисправностей Аппаратное устройство, с помощью которого реализуется концепция Remote Service, представляет собой коммуникационный блок, работающий аналогично черному ящику самолета (рис. 1). Этот блок считывает диагностические данные из контроллера робота и передает их по каналу GSM. Считывается не только информация, необходимая для оказания немедленной помощи в случае отказа, но и сведения, позволяющие контролировать и анализировать состояние робота для прогнозирования неисправностей и планирования технического обслуживания.If the robot breaks down, the service box immediately stores the status of the robot, its historical data (as log files), and diagnostic parameters such as temperature and power supply. Equipped with a built-in modem and using the GSM network, the box transmits the data to a central server for analysis and presentation on a dedicated Web site. Alerts are automatically sent to the nearest of ABB’s 1,200 robot service engineers who then accesses the detailed data and error log to analyze the problem.При поломке робота сервисный блок немедленно сохраняет данные о его состоянии, сведения из рабочего журнала, а также значения диагностических параметров (температура и характеристики питания). Эти данные передаются встроенным GSM-модемом на центральный сервер для анализа и представления на соответствующем web-сайте. Аварийные сообщения автоматически пересылаются ближайшему к месту аварии одному из 1200 сервисных инженеров-робототехников АББ, который получает доступ к детальной информации и журналу аварий для анализа возникшей проблемы.A remotely based ABB engineer can then quickly identify the exact fault, offering rapid customer support. For problems that cannot be solved remotely, the service engineer can arrange for quick delivery of spare parts and visit the site to repair the robot. Even if the engineer must make a site visit, service is faster, more efficient and performed to a higher standard than otherwise possible.Специалист АББ может дистанционно идентифицировать отказ и оказать быструю помощь заказчику. Если неисправность не может быть устранена дистанционно, сервисный инженер организовывает доставку запасных частей и выезд ремонтной бригады. Даже если необходимо разрешение проблемы на месте, предшествующая дистанционная диагностика позволяет минимизировать объем работ и сократить время простоя.Remote Service enables engineers to “talk” to robots remotely and to utilize tools that enable smart, fast and automatic analysis. The system is based on a machine-to-machine (M2M) concept, which works automatically, requiring human input only for analysis and personalized customer recommendations. ABB was recognized for this innovative solution at the M2M United Conference in Chicago in 2008 Factbox.Remote Service позволяет инженерам «разговаривать» с роботами на расстоянии и предоставляет в их распоряжение интеллектуальные средства быстрого автоматизированного анализа. Система основана на основе технологии автоматической связи машины с машиной (M2M), где участие человека сводится к анализу данных и выдаче рекомендаций клиенту. В 2008 г. это инновационное решение от АББ получило приз на конференции M2M United Conference в Чикаго (см. вставку).Proactive maintenanceRemote Service also allows ABB engineers to monitor and detect potential problems in the robot system and opens up new possibilities for proactive maintenance.Прогнозирование неисправностейRemote Service позволяет инженерам АББ дистанционно контролировать состояние роботов и прогнозировать возможные неисправности, что открывает новые возможности по организации профилактического обслуживания.The service box regularly takes condition measurements. By monitoring key parameters over time, Remote Service can identify potential failures and when necessary notify both the end customer and the appropriate ABB engineer. The management and storage of full system backups is a very powerful service to help recover from critical situations caused, for example, by operator errors.Сервисный блок регулярно выполняет диагностические измерения. Непрерывно контролируя ключевые параметры, Remote Service может распознать потенциальные опасности и, при необходимости, оповещать владельца оборудования и соответствующего специалиста АББ. Резервирование данных для возможного отката является мощным средством, обеспечивающим восстановление системы в критических ситуациях, например, после ошибки оператора.The first Remote Service installation took place in the automotive industry in the United States and quickly proved its value. The motherboard in a robot cabinet overheated and the rise in temperature triggered an alarm via Remote Service. Because of the alarm, engineers were able to replace a faulty fan, preventing a costly production shutdown.Первая система Remote Service была установлена на автозаводе в США и очень скоро была оценена по достоинству. Она обнаружила перегрев материнской платы в шкафу управления роботом и передала сигнал о превышении допустимой температуры, благодаря чему инженеры смогли заменить неисправный вентилятор и предотвратить дорогостоящую остановку производства.MyRobot: 24-hour remote access
Having regular access to a robot’s condition data is also essential to achieving lean production. At any time, from any location, customers can verify their robots’ status and access maintenance information and performance reports simply by logging in to ABB’s MyRobot Web site. The service enables customers to easily compare performances, identify bottlenecks or developing issues, and initiate the mostСайт MyRobot: круглосуточный дистанционный доступДля того чтобы обеспечить бесперебойное производство, необходимо иметь регулярный доступ к информации о состоянии робота. Зайдя на соответствующую страницу сайта MyRobot компании АББ, заказчики получат все необходимые данные, включая сведения о техническом обслуживании и отчеты о производительности своего робота. Эта услуга позволяет легко сравнивать данные о производительности, обнаруживать возможные проблемы, а также оптимизировать планирование технического обслуживания и модернизации. С помощью MyRobot можно значительно увеличить выпуск продукции и уменьшить количество выбросов.Award-winning solutionIn June 2008, the innovative Remote Service solution won the Gold Value Chain award at the M2M United Conference in Chicago. The value chain award honors successful corporate adopters of M2M (machine–to-machine) technology and highlights the process of combining multiple technologies to deliver high-quality services to customers. ABB won in the categoryof Smart Services.Приз за удачное решениеВ июне 2008 г. инновационное решение Remote Service получило награду Gold Value Chain (Золотая цепь) на конференции M2M United Conference в Чикаго. «Золотая цепь» присуждается за успешное масштабное внедрение технологии M2M (машина – машина), а также за достижения в объединении различных технологий для предоставления высококачественных услуг заказчикам. АББ одержала победу в номинации «Интеллектуальный сервис».Case study: Tetley Tetley GB Ltd is the world’s second-largest manufacturer and distributor of tea. The company’s manufacturing and distribution business is spread across 40 countries and sells over 60 branded tea bags. Tetley’s UK tea production facility in Eaglescliffe, County Durham is the sole producer of Tetley tea bags 2.Пример применения: Tetley Компания TetleyGB Ltd является вторым по величине мировым производителем и поставщиком чая. Производственные и торговые филиалы компании имеются в 40 странах, а продукция распространяется под 60 торговыми марками. Чаеразвесочная фабрика в Иглсклифф, графство Дарем, Великобритания – единственный производитель чая Tetley в пакетиках (рис. 2).ABB offers a flexible choice of service agreements for both new and existing robot installations, which can help extend the mean time between failures, shorten the time to repair and lower the cost of automated production.Предлагаемые АББ контракты на выполнение технического обслуживания как уже имеющихся, так и вновь устанавливаемых роботов, позволяют значительно увеличить среднюю наработку на отказ, сократить время ремонта и общую стоимость автоматизированного производства.Robots in the plant’s production line were tripping alarms and delaying the whole production cycle. The spurious alarms resulted in much unnecessary downtime that was spent resetting the robots in the hope that another breakdown could be avoided. Each time an alarm was tripped, several hours of production time was lost. “It was for this reason that we were keen to try out ABB’s Remote Service agreement,” said Colin Trevor, plant maintenance manager.Установленные в технологической линии роботы выдавали аварийные сигналы, задерживающие выполнение производственного цикла. Ложные срабатывания вынуждали перезапускать роботов в надежде предотвратить возможные отказы, в результате чего после каждого аварийного сигнала производство останавливалось на несколько часов. «Именно поэтому мы решили попробовать заключить с АББ контракт на дистанционное техническое обслуживание», – сказал Колин Тревор, начальник технической службы фабрики.To prevent future disruptions caused by unplanned downtime, Tetley signed an ABB Response Package service agreement, which included installing a service box and system infrastructure into the robot control systems. Using the Remote Service solution, ABB remotely monitors and collects data on the “wear and tear” and productivity of the robotic cells; this data is then shared with the customer and contributes to smooth-running production cycles.Для предотвращения ущерба в результате незапланированных простоев Tetley заключила с АББ контракт на комплексное обслуживание Response Package, согласно которому системы управления роботами были дооборудованы сервисными блоками с необходимой инфраструктурой. С помощью Remote Service компания АББ дистанционно собирает данные о наработке, износе и производительности роботизированных модулей. Эти данные предоставляются заказчику для оптимизации загрузки производственного оборудования.Higher production uptimeSince the implementation of Remote Service, Tetley has enjoyed greatly reduced robot downtime, with no further disruptions caused by unforeseen problems. “The Remote Service package has dramatically changed the plant,” said Trevor. “We no longer have breakdown issues throughout the shift, helping us to achieve much longer periods of robot uptime. As we have learned, world-class manufacturing facilities need world-class support packages. Remote monitoring of our robots helps us to maintain machine uptime, prevent costly downtime and ensures my employees can be put to more valuable use.”Увеличение полезного времениС момента внедрения Remote Service компания Tetley была приятно удивлена резким сокращением простоя роботов и отсутствием незапланированных остановок производства. «Пакет Remote Service резко изменил ситуацию на предприятии», – сказал Тревор. «Мы избавились от простоев роботов и смогли резко увеличить их эксплуатационную готовность. Мы поняли, что для производственного оборудования мирового класса необходим сервисный пакет мирового класса. Дистанционный контроль роботов помогает нам поддерживать их в рабочем состоянии, предотвращать дорогостоящие простои и задействовать наш персонал для выполнения более важных задач».Service accessRemote Service is available worldwide, connecting more than 500 robots. Companies that have up to 30 robots are often good candidates for the Remote Service offering, as they usually have neither the engineers nor the requisite skills to deal with robotics faults themselves. Larger companies are also enthusiastic about Remote Service, as the proactive services will improve the lifetime of their equipment and increase overall production uptime.Доступность сервисаСеть Remote Service охватывает более 700 роботов по всему миру. Потенциальными заказчиками Remote Service являются компании, имеющие до 30 роботов, но не имеющие инженеров и техников, способных самостоятельно устранять их неисправности. Интерес к Remote Service проявляют и более крупные компании, поскольку они заинтересованы в увеличении срока службы и эксплуатационной готовности производственного оборудования.In today’s competitive environment, business profitability often relies on demanding production schedules that do not always leave time for exhaustive or repeated equipment health checks. ABB’s Remote Service agreements are designed to monitor its customers’ robots to identify when problems are likely to occur and ensure that help is dispatched before the problem can escalate. In over 60 percent of ABB’s service calls, its robots can be brought back online remotely, without further intervention.В условиях современной конкуренции окупаемость бизнеса часто зависит от соблюдения жестких графиков производства, не оставляющих времени для полномасштабных или периодических проверок исправности оборудования. Контракт Remote Service предусматривает мониторинг состояния роботов заказчика для прогнозирования возможных неисправностей и принятие мер по их предотвращению. В более чем 60 % случаев для устранения неисправности достаточно дистанционной консультации в сервисной службе АББ, дальнейшего вмешательства не требуется.ABB offers a flexible choice of service agreements for both new and existing robot installations, which helps extend the mean time between failures, shorten the time to repair and lower the total cost of ownership. With four new packages available – Support, Response, Maintenance and Warranty, each backed up by ABB’s Remote Service technology – businesses can minimize the impact of unplanned downtime and achieve improved production-line efficiency.Компания АББ предлагает гибкий выбор контрактов на выполнение технического обслуживания как уже имеющихся, так и вновь устанавливаемых роботов, которые позволяют значительно увеличить среднюю наработку на отказ, сократить время ремонта и эксплуатационные расходы. Четыре новых пакета на основе технологии Remote Service – Support, Response, Maintenance и Warranty – позволяют минимизировать внеплановые простои и значительно повысить эффективность производства.The benefits of Remote Sevice are clear: improved availability, fewer service visits, lower maintenance costs and maximized total cost of ownership. This unique service sets ABB apart from its competitors and is the beginning of a revolution in service thinking. It provides ABB with a great opportunity to improve customer access to its expertise and develop more advanced services worldwide.Преимущества дистанционного технического обслуживания очевидны: повышенная надежность, уменьшение выездов ремонтных бригад, уменьшение затрат на обслуживание и общих эксплуатационных расходов. Эта уникальная услуга дает компании АББ преимущества над конкурентами и демонстрирует революционный подход к организации сервиса. Благодаря ей компания АББ расширяет доступ заказчиков к опыту своих специалистов и получает возможность более эффективного оказания технической помощи по всему миру.Тематики

6 Artificial Intelligence
In my opinion, none of [these programs] does even remote justice to the complexity of human mental processes. Unlike men, "artificially intelligent" programs tend to be single minded, undistractable, and unemotional. (Neisser, 1967, p. 9)Future progress in [artificial intelligence] will depend on the development of both practical and theoretical knowledge.... As regards theoretical knowledge, some have sought a unified theory of artificial intelligence. My view is that artificial intelligence is (or soon will be) an engineering discipline since its primary goal is to build things. (Nilsson, 1971, pp. vii-viii)Most workers in AI [artificial intelligence] research and in related fields confess to a pronounced feeling of disappointment in what has been achieved in the last 25 years. Workers entered the field around 1950, and even around 1960, with high hopes that are very far from being realized in 1972. In no part of the field have the discoveries made so far produced the major impact that was then promised.... In the meantime, claims and predictions regarding the potential results of AI research had been publicized which went even farther than the expectations of the majority of workers in the field, whose embarrassments have been added to by the lamentable failure of such inflated predictions....When able and respected scientists write in letters to the present author that AI, the major goal of computing science, represents "another step in the general process of evolution"; that possibilities in the 1980s include an all-purpose intelligence on a human-scale knowledge base; that awe-inspiring possibilities suggest themselves based on machine intelligence exceeding human intelligence by the year 2000 [one has the right to be skeptical]. (Lighthill, 1972, p. 17)4) Just as Astronomy Succeeded Astrology, the Discovery of Intellectual Processes in Machines Should Lead to a Science, EventuallyJust as astronomy succeeded astrology, following Kepler's discovery of planetary regularities, the discoveries of these many principles in empirical explorations on intellectual processes in machines should lead to a science, eventually. (Minsky & Papert, 1973, p. 11)5) Problems in Machine Intelligence Arise Because Things Obvious to Any Person Are Not Represented in the ProgramMany problems arise in experiments on machine intelligence because things obvious to any person are not represented in any program. One can pull with a string, but one cannot push with one.... Simple facts like these caused serious problems when Charniak attempted to extend Bobrow's "Student" program to more realistic applications, and they have not been faced up to until now. (Minsky & Papert, 1973, p. 77)What do we mean by [a symbolic] "description"? We do not mean to suggest that our descriptions must be made of strings of ordinary language words (although they might be). The simplest kind of description is a structure in which some features of a situation are represented by single ("primitive") symbols, and relations between those features are represented by other symbols-or by other features of the way the description is put together. (Minsky & Papert, 1973, p. 11)[AI is] the use of computer programs and programming techniques to cast light on the principles of intelligence in general and human thought in particular. (Boden, 1977, p. 5)The word you look for and hardly ever see in the early AI literature is the word knowledge. They didn't believe you have to know anything, you could always rework it all.... In fact 1967 is the turning point in my mind when there was enough feeling that the old ideas of general principles had to go.... I came up with an argument for what I called the primacy of expertise, and at the time I called the other guys the generalists. (Moses, quoted in McCorduck, 1979, pp. 228-229)9) Artificial Intelligence Is Psychology in a Particularly Pure and Abstract FormThe basic idea of cognitive science is that intelligent beings are semantic engines-in other words, automatic formal systems with interpretations under which they consistently make sense. We can now see why this includes psychology and artificial intelligence on a more or less equal footing: people and intelligent computers (if and when there are any) turn out to be merely different manifestations of the same underlying phenomenon. Moreover, with universal hardware, any semantic engine can in principle be formally imitated by a computer if only the right program can be found. And that will guarantee semantic imitation as well, since (given the appropriate formal behavior) the semantics is "taking care of itself" anyway. Thus we also see why, from this perspective, artificial intelligence can be regarded as psychology in a particularly pure and abstract form. The same fundamental structures are under investigation, but in AI, all the relevant parameters are under direct experimental control (in the programming), without any messy physiology or ethics to get in the way. (Haugeland, 1981b, p. 31)There are many different kinds of reasoning one might imagine:Formal reasoning involves the syntactic manipulation of data structures to deduce new ones following prespecified rules of inference. Mathematical logic is the archetypical formal representation. Procedural reasoning uses simulation to answer questions and solve problems. When we use a program to answer What is the sum of 3 and 4? it uses, or "runs," a procedural model of arithmetic. Reasoning by analogy seems to be a very natural mode of thought for humans but, so far, difficult to accomplish in AI programs. The idea is that when you ask the question Can robins fly? the system might reason that "robins are like sparrows, and I know that sparrows can fly, so robins probably can fly."Generalization and abstraction are also natural reasoning process for humans that are difficult to pin down well enough to implement in a program. If one knows that Robins have wings, that Sparrows have wings, and that Blue jays have wings, eventually one will believe that All birds have wings. This capability may be at the core of most human learning, but it has not yet become a useful technique in AI.... Meta- level reasoning is demonstrated by the way one answers the question What is Paul Newman's telephone number? You might reason that "if I knew Paul Newman's number, I would know that I knew it, because it is a notable fact." This involves using "knowledge about what you know," in particular, about the extent of your knowledge and about the importance of certain facts. Recent research in psychology and AI indicates that meta-level reasoning may play a central role in human cognitive processing. (Barr & Feigenbaum, 1981, pp. 146-147)Suffice it to say that programs already exist that can do things-or, at the very least, appear to be beginning to do things-which ill-informed critics have asserted a priori to be impossible. Examples include: perceiving in a holistic as opposed to an atomistic way; using language creatively; translating sensibly from one language to another by way of a language-neutral semantic representation; planning acts in a broad and sketchy fashion, the details being decided only in execution; distinguishing between different species of emotional reaction according to the psychological context of the subject. (Boden, 1981, p. 33)Can the synthesis of Man and Machine ever be stable, or will the purely organic component become such a hindrance that it has to be discarded? If this eventually happens-and I have... good reasons for thinking that it must-we have nothing to regret and certainly nothing to fear. (Clarke, 1984, p. 243)The thesis of GOFAI... is not that the processes underlying intelligence can be described symbolically... but that they are symbolic. (Haugeland, 1985, p. 113)14) Artificial Intelligence Provides a Useful Approach to Psychological and Psychiatric Theory FormationIt is all very well formulating psychological and psychiatric theories verbally but, when using natural language (even technical jargon), it is difficult to recognise when a theory is complete; oversights are all too easily made, gaps too readily left. This is a point which is generally recognised to be true and it is for precisely this reason that the behavioural sciences attempt to follow the natural sciences in using "classical" mathematics as a more rigorous descriptive language. However, it is an unfortunate fact that, with a few notable exceptions, there has been a marked lack of success in this application. It is my belief that a different approach-a different mathematics-is needed, and that AI provides just this approach. (Hand, quoted in Hand, 1985, pp. 6-7)We might distinguish among four kinds of AI.Research of this kind involves building and programming computers to perform tasks which, to paraphrase Marvin Minsky, would require intelligence if they were done by us. Researchers in nonpsychological AI make no claims whatsoever about the psychological realism of their programs or the devices they build, that is, about whether or not computers perform tasks as humans do.Research here is guided by the view that the computer is a useful tool in the study of mind. In particular, we can write computer programs or build devices that simulate alleged psychological processes in humans and then test our predictions about how the alleged processes work. We can weave these programs and devices together with other programs and devices that simulate different alleged mental processes and thereby test the degree to which the AI system as a whole simulates human mentality. According to weak psychological AI, working with computer models is a way of refining and testing hypotheses about processes that are allegedly realized in human minds.... According to this view, our minds are computers and therefore can be duplicated by other computers. Sherry Turkle writes that the "real ambition is of mythic proportions, making a general purpose intelligence, a mind." (Turkle, 1984, p. 240) The authors of a major text announce that "the ultimate goal of AI research is to build a person or, more humbly, an animal." (Charniak & McDermott, 1985, p. 7)Research in this field, like strong psychological AI, takes seriously the functionalist view that mentality can be realized in many different types of physical devices. Suprapsychological AI, however, accuses strong psychological AI of being chauvinisticof being only interested in human intelligence! Suprapsychological AI claims to be interested in all the conceivable ways intelligence can be realized. (Flanagan, 1991, pp. 241-242)16) Determination of Relevance of Rules in Particular ContextsEven if the [rules] were stored in a context-free form the computer still couldn't use them. To do that the computer requires rules enabling it to draw on just those [ rules] which are relevant in each particular context. Determination of relevance will have to be based on further facts and rules, but the question will again arise as to which facts and rules are relevant for making each particular determination. One could always invoke further facts and rules to answer this question, but of course these must be only the relevant ones. And so it goes. It seems that AI workers will never be able to get started here unless they can settle the problem of relevance beforehand by cataloguing types of context and listing just those facts which are relevant in each. (Dreyfus & Dreyfus, 1986, p. 80)Perhaps the single most important idea to artificial intelligence is that there is no fundamental difference between form and content, that meaning can be captured in a set of symbols such as a semantic net. (G. Johnson, 1986, p. 250)Artificial intelligence is based on the assumption that the mind can be described as some kind of formal system manipulating symbols that stand for things in the world. Thus it doesn't matter what the brain is made of, or what it uses for tokens in the great game of thinking. Using an equivalent set of tokens and rules, we can do thinking with a digital computer, just as we can play chess using cups, salt and pepper shakers, knives, forks, and spoons. Using the right software, one system (the mind) can be mapped into the other (the computer). (G. Johnson, 1986, p. 250)19) A Statement of the Primary and Secondary Purposes of Artificial IntelligenceThe primary goal of Artificial Intelligence is to make machines smarter.The secondary goals of Artificial Intelligence are to understand what intelligence is (the Nobel laureate purpose) and to make machines more useful (the entrepreneurial purpose). (Winston, 1987, p. 1)The theoretical ideas of older branches of engineering are captured in the language of mathematics. We contend that mathematical logic provides the basis for theory in AI. Although many computer scientists already count logic as fundamental to computer science in general, we put forward an even stronger form of the logic-is-important argument....AI deals mainly with the problem of representing and using declarative (as opposed to procedural) knowledge. Declarative knowledge is the kind that is expressed as sentences, and AI needs a language in which to state these sentences. Because the languages in which this knowledge usually is originally captured (natural languages such as English) are not suitable for computer representations, some other language with the appropriate properties must be used. It turns out, we think, that the appropriate properties include at least those that have been uppermost in the minds of logicians in their development of logical languages such as the predicate calculus. Thus, we think that any language for expressing knowledge in AI systems must be at least as expressive as the first-order predicate calculus. (Genesereth & Nilsson, 1987, p. viii)21) Perceptual Structures Can Be Represented as Lists of Elementary PropositionsIn artificial intelligence studies, perceptual structures are represented as assemblages of description lists, the elementary components of which are propositions asserting that certain relations hold among elements. (Chase & Simon, 1988, p. 490)Artificial intelligence (AI) is sometimes defined as the study of how to build and/or program computers to enable them to do the sorts of things that minds can do. Some of these things are commonly regarded as requiring intelligence: offering a medical diagnosis and/or prescription, giving legal or scientific advice, proving theorems in logic or mathematics. Others are not, because they can be done by all normal adults irrespective of educational background (and sometimes by non-human animals too), and typically involve no conscious control: seeing things in sunlight and shadows, finding a path through cluttered terrain, fitting pegs into holes, speaking one's own native tongue, and using one's common sense. Because it covers AI research dealing with both these classes of mental capacity, this definition is preferable to one describing AI as making computers do "things that would require intelligence if done by people." However, it presupposes that computers could do what minds can do, that they might really diagnose, advise, infer, and understand. One could avoid this problematic assumption (and also side-step questions about whether computers do things in the same way as we do) by defining AI instead as "the development of computers whose observable performance has features which in humans we would attribute to mental processes." This bland characterization would be acceptable to some AI workers, especially amongst those focusing on the production of technological tools for commercial purposes. But many others would favour a more controversial definition, seeing AI as the science of intelligence in general-or, more accurately, as the intellectual core of cognitive science. As such, its goal is to provide a systematic theory that can explain (and perhaps enable us to replicate) both the general categories of intentionality and the diverse psychological capacities grounded in them. (Boden, 1990b, pp. 1-2)Because the ability to store data somewhat corresponds to what we call memory in human beings, and because the ability to follow logical procedures somewhat corresponds to what we call reasoning in human beings, many members of the cult have concluded that what computers do somewhat corresponds to what we call thinking. It is no great difficulty to persuade the general public of that conclusion since computers process data very fast in small spaces well below the level of visibility; they do not look like other machines when they are at work. They seem to be running along as smoothly and silently as the brain does when it remembers and reasons and thinks. On the other hand, those who design and build computers know exactly how the machines are working down in the hidden depths of their semiconductors. Computers can be taken apart, scrutinized, and put back together. Their activities can be tracked, analyzed, measured, and thus clearly understood-which is far from possible with the brain. This gives rise to the tempting assumption on the part of the builders and designers that computers can tell us something about brains, indeed, that the computer can serve as a model of the mind, which then comes to be seen as some manner of information processing machine, and possibly not as good at the job as the machine. (Roszak, 1994, pp. xiv-xv)The inner workings of the human mind are far more intricate than the most complicated systems of modern technology. Researchers in the field of artificial intelligence have been attempting to develop programs that will enable computers to display intelligent behavior. Although this field has been an active one for more than thirty-five years and has had many notable successes, AI researchers still do not know how to create a program that matches human intelligence. No existing program can recall facts, solve problems, reason, learn, and process language with human facility. This lack of success has occurred not because computers are inferior to human brains but rather because we do not yet know in sufficient detail how intelligence is organized in the brain.

c black fonction [fɔ̃ksjɔ̃]feminine nouna. functionc black b. ( = métier) office━━━━━━━━━━━━━━━━━✎ Le mot anglais s'écrit avec - un- au début.━━━━━━━━━━━━━━━━━The term la fonction publique has great cultural significance in France, and covers a much broader range of activities than the English term « civil service ». There are almost three million « fonctionnaires » (also known as « agents de l'État ») in France. They include teachers, social services staff, post office workers and employees of the French rail service.Because this status theoretically guarantees total job security, « fonctionnaires » are sometimes stereotyped as being unfairly privileged compared to private sector employees. → CONCOURS* * *fɔ̃ksjɔ̃prendre ses fonctions, entrer en fonctions — to take up one's post

10 адаптивная программа
Адаптивной называется та программа, которая изменяет свой уровень трудности в зависимости от характера ответов учащегося. Такие программы обычно включаются в механизмы управления машинами, обучающими навыкам ручного труда или другим навыкам. Скорость работы учащегося или частота появления ошибок распознаются машиной, параметры которой изменяются соответствующим образом. — The adaptive program is one which alters its own level of difficulty according to the student's level of performance. Such programs are normally incorporated the control mechanisms of machines which teach manual or other skills. The learner's speed or error-rate are detected by the machine, the parameters of which are altered as appropriate.
