Religious hatred put school kids in blood shed
Z.R.Hong 2012-3-22 21:43
http://edition.cnn.com/2012/03/22/world/europe/france-shooting/index.html?hpt=hp_t1 We can see from this link the most bloody massacre ever in an elementary school committed by aldult(s). How much hatred do humans have against others due to some reasons or non? How much the price did the murderers pay for his insane achievement? Lives of innocent children and himself. That is too much. How much love is need to devour the hatred. How can we bound wounded hearts, and put crazy souls into peace? Just too many questions at this moment. It reminds me that similar mishap happened in China recently. A jobless man cut throats of the school children, because of the strong willing to revenge the society, putting beast anger on irrelevant infants. What should we do to cure the disease?

Please upgrade your browser and return later. Health and Safety in the Home The au pair will learn how to prevent disease and keep their host family and home safe and healthy. Teachers discuss and demonstrate universal health precautions such as hand washing and disinfecting. These are both important techniques to utilize in order to keep germs and bacteria from spreading. They should be practiced regularly and when working with children should be especially careful while diapering and disposing of diapers as well as when feeding infants. This careful attention to eliminating germs and bacteria coupled with an emphasis on exercise, fresh air and rest will maintain a healthy safe home. Food Nutrition Au pairs will learn that a child needs nutritious meals and snacks in order to grow and develop. While living with their host family and taking care of children they will be actively participating in the provision of good nutrition each and every day. As a class they will cover various scenarios and situations that they may encounter during their year as an au pair. Starting solid food will certainly be an important topic for those au pairs who will be caring for infants. They will learn about developmental feeding milestones so that they know what children of all ages should be consuming. A close study of the food pyramid will supplement this knowledge as the au pairs learn about food groups, serving sizes and fun food activities to help their children eat healthy food. Also, an important subject when discussing food and nutrition is eating disorders. This is a topic that the au pairs will become familiar with in order to keep themselves and their friends healthy as well as their host families. Common Childhood Diseases As the Au Pairs experience a full year with their host family they will encounter many days when they need to identify symptoms of an illness. Teachers will discuss general warning signs of common illnesses followed by tips and helpful hints for taking care of sick children. They will also cover common childhood health problems such as allergies, asthma, chicken pox, diaper rash, and the common cold which many au pairs will encounter with their host children. They will learn about a wide variety of health problems in order to be better prepared for a year of childcare in the US. In addition they will learn about immunizations that can help prevent many childhood diseases. As vaccinations vary from country to country it is important that Au Pairs know what their children are immunized against. Safety and Emergency Education Teachers give au pairs and overview of basic first aid and what to do in case of an emergency. There is a strong emphasis on the fact that this is not a first aid course and the au pairs are encouraged to take a first aid course within the first 3 months of their stay in the United States. The key points of this segment of the training are being prepared; having first aid kits stocked and accessible and to always check with parents before administering medicine to a child. Au pairs are taught how to make a home safety checklist and to childproof the various rooms in the home. While discussing safety at home, teachers touch upon gun safety and the risks around home exercise equipment as well. Risks outside of the home are covered as well. Vehicle safety, school bus safety, bicycle safety and other topics that pertain to daily life with a child are covered. Effective Communication Tips for good communication with host children and host parents are given an practiced in order to be prepared to begin the year as an au pair. Effective communication is broken down into categories that are easy to understand and put into practice: never assume, be pleasant, think, listen and understand, respect and facial expressions and body language. Each of these subcategories is practiced during class and in the communication workshop. Other techniques such as frequent sharing and a daily communication log are suggested. The importance of verbal and non-verbal as well as written communication is stressed as English levels vary and not everything will be interpreted the way it was intended by the host family and/or the au pair. Au Pairs as Role Models As a day to day influence in their host families’ life each au pair is a role model in their home. The au pairs learn that host children will look up to them and imitate their attitudes and behaviors. It is important for au pairs to work closely with the host parents and to look at them as partners. From the first time they meet an au pair should get to know each family member and learn about their interests and values so that the au pair can incorporate them into the daily activities so that she can reciprocate by sharing her culture with them in a fun way. An au pair must be very aware of her habits and appearance. Smoking can be a sensitive issue with a host family especially concerning host children and exposure to second hand smoke. Not only can this affect the children's health but having a smoker in the house can influence their attitude towards smoking, making it an attractive option. Au pairs must also be sure to present themselves appropriately being careful to dress reasonably and to consult host parents about any piercings or tattoos that the children may see. Another concern is computer safety. An au pair can help to monitor her host children's computer use but she should also be careful when she is using the computer so as to not put herself or her host children in danger. Being an au pair can be stressful. There is a lot of responsibility and the au pair has to think about how she is influencing her host children at all times. It is important to be able to identify and manage stress so that it will not affect her health, behavior or quality of care. Ages Stages: Birth to Teenage Years The au pairs learn that children continue to develop from birth through their teenage years. The teachers emphasize that each child develops at his or her own pace. Development is broken down into different categories that can be followed during each year of a child's life. These categories are: physical development, language development, cognitive development, social-emotional development. Within each of these categories au pairs learn about important development landmarks to watch for. Each age group is discussed in terms of these four categories. Au pairs split up to do extensive research on the ages groups that they will be caring for so that they have a better idea of what to expect during their year as an au pair. Age-appropriate Materials and Activities Au pairs learn about toys, learning materials, and activities that are age appropriate in order to help their host children learn, have fun and stay safe throughout their year together. General interests of children in each age group are discussed, with the understanding that children's interest vary and may not fit neatly into these categories. Next, the teachers discuss how to select safe toys for their host children. They go over resources for creative development that may prove as an alternative for TV or video games and will help them to get involved in their local community. Finally, they are presented with a reading list for children which provides titles and authors of books for a wide range of ages. Building Self-esteem in Children Au pairs learn to emphasize the importance of beginning at the earliest age to develop a child's positive self-concept and to explore ways to do this. An au pair, a major influence in the life of a host child, has the task of supporting development by modeling skills of compassion, tolerance and love. These actions help to build a positive self-concept in children which will help determine the child's success in both school and later in life. The au pairs are taught how to respect children's identities and help to support children when they are hurt and to make it clear when behavior is unacceptable leading toward conflict resolution. They learn to teach fairness and to answer questions directly, encourage pride and finally to help children help themselves. It is important to be aware of the other influences in the host children's lives including friends, books and toys to help evaluate them for bias and stereotyping. Behavior Management Au pairs learn to emphasize the importance of beginning at the earliest age to develop a child's positive self-concept and ways to do this. Teachers provide hints for positive behavior management. They learn how to structure a child's environment in order to make it safe and child friendly. Au pairs learn to use natural or logical consequences, a system of punishments and rewards that are appropriate for the situation. Next, they learn to offer the children choices whenever possible and, when a child's behavior is inappropriate, to talk about the behavior and not the child. Au pairs are reminded to use positive statements, to expect cooperation and to be consistent in enforcing rules. Au pairs can also help their host children to use their words instead of force and to solve problems democratically. A variety of common behavioral issues and disciplinary approaches are discussed in order to give an overview of what the au pairs may encounter throughout their year. Cultural Care Au Pair * Cultural Care Au Pair is the largest and most experienced au pair organization in the U.S., having successfully placed more than 75,000 au pairs in welcoming American homes since 1989. http://www.aupairtrainingschool.com/classes.html

[转载]Waldorf school (給人腦一個受教育的空間)
tsowungwai 2011-10-24 05:54
今日纽约时报报导,美国有一个叫 waldorf school 组织。 旗下有一百九十多个学校。但不用电脑,也不允许小孩用电脑, 而用传统的教学方法 来教育小孩。送子女去上学的家长,大多数是 高科技公司主管,都在 google,apple,ebay 及许多其它高科技公司任高职。 这些人为什么不要自己小孩接触电脑?答案很简单。因为电脑限制小孩的创作能力。 限制小孩的思维方式,限制小孩的正常成长。限制小孩与他人的正常交往。 小孩每时每刻对着电脑,只会为社会制造社会自闭症。 只有传统教育方式才能启发孩子。 成年人已定型,可接受电脑。 但孩子一上来用电脑则腐其心志,有何好处? 吴先生对这么清楚的事还要问,是不是论坛最近太安静了? 梅姐

How far is a college student willing to go (in the US)?

Tuition is not cheap for out-of-state students at a state university. So, you would think that they would come to classes and do their homework so that their money or their parents' money is not wasted. Well, one of my former students said her brother died (so she had to be away for days), but could not provide any evidence. I heard that such excuse is used routinely by undergraduate students. May God bless these students' relatives!

[转载]Winter School on Complex Systems
fangjinqin 2010-11-11 08:09
New England Complex Systems Institute Winter School on Complex Systems We are pleased to announce the dates of our upcoming courses on complex systems: Jan. 3-7, 2011 / Complex Physical, Biological Social Systems Jan. 9, 2011 / Computer Programming and Complex Systems Jan. 10-14, 2011 / Complex Systems Modeling and Networks Target Audience These courses are intended for faculty, graduate students, post- doctoral fellows, professionals and others who would like to gain an understanding of the fundamentals of complex systems, and develop methodological tools for conducting research in their respective fields, or as a basis for pursuing complex systems research. The winter school offers two intensive week-long courses. The courses consist of lectures, discussions, and supervised group projects. Though the second week builds on material covered in the previous week, CX201 is not a prerequisite for CX202. You may register for either or both weeks. If desired, arrangements for credit at a home institution may be made in advance. See course descriptions below or online at: www.necsi.edu/education/school.html WEEK ONE CX201: Complex Physical, Biological and Social Systems Dates: January 3-7, 2011|Location: MIT, Cambridge, MA This course offers an introduction to the essential concepts of complex systems and related mathematical methods and simulation strategies with application to physical, biological and social systems. The course will particularly focus on the use of multiscale representations as a unifying approach to complex systems concepts, methods and applications. Concepts to be discussed include: emergence, complexity, networks, self-organization, pattern formation, evolution, adaptation, fractals, chaos, cooperation, competition, attractors, interdependence, scaling, dynamic response, information, and function. Methods to be discussed include: statistical methods, cellular automata, agent-based modeling, pattern recognition, system representation and informatics. LAB CX102: Computer Programming and Complex Systems Date: January 9, 2011|Location: MIT, Cambridge, MA This course introduces computer programming in the Python language for those with little or no computer programming experience. It is designed as a precursor to CX202. The course will present programming concepts and hands-on exercises. Topics to be covered include: data structures, algorithms, variables and assignments, numerical and logical operations, lists and dictionaries, user-defined functions, flow control, loops, and visualization. WEEK TWO CX202: Complex Systems Modeling and Networks Dates: January 10-14, 2011|Location: MIT, Cambridge, MA This course provides (a) an introduction to building models of complex systems (physical, biological, social and engineered), and (b) the study of networks, including topologies and dynamics of real world networks. The course will cover the basic construction and analysis of models including identifying what is to be modeled, constructing a mathematical representation, analysis tools and implementing and simulating the model in a computer program. Particular attention will be paid to choosing the right level of detail for the model, testing its robustness, and discussing which questions a given model can or cannot answer. The study of networks will introduce the use of network topologies and the characterization of networks describing complex systems, including such concepts as small worlds, degree distribution, diameter, clustering coefficient, modules, and motifs. Different types of network topologies and network behaviors that model aspects of real complex systems will be described including: modular, sparse, random, scale-free, influence, transport, transformation, and structure. NOTE: Students without a background in programming are strongly recommended to attend CX102: Computer Programming and Complex Systems in conjunction with CX202. Comments from past students Excellent course... useful thematic overview... applications in diverse contexts were exciting. Particularly appreciated the group project - excellent experiential pedagogy. The course was an eye-opening framework to analyze my work through a different lens. Presentations were extremely useful for me in understanding how to begin modeling complex systems and assessing them. Helped me understand a lot of things I have been doing so far without clearly understanding the principles. This class very much stretched my mind to apply the ideas of complexity to the world... I believe I learned more on a grander scale...will help enrich my vocabulary and the way of thinking in the world with respect to complexity. Excellent class. I hope to take a more active role in the community. For more information and registration: www.necsi.edu/education/school.html

小记 来哈尔滨之前,曾有想过,回来写篇日志,记录一下这次学习经历。但后来有事就给搁浅了。现在章老师希望有个书面汇报,于是写了一篇文档,顺道一并写了这篇博文。不曾想,这也竟是我在科学网博客自己写的第一篇博文 时间: 2010.8.16~2010.8.20 研讨班: 2010 暑期研讨班(自然语言处理) 地点:哈尔滨工业大学 与会学生人数: 73 人左右 特邀报告人: 4 名 2010 HIT-MSRA Summer School On Human Language Technology ,哈尔滨 研讨班共有 5 天, 2.5 天课程, 2.5 天 Project 。 研讨班主页: http://mitlab.hit.edu.cn/2010summer/zh_index.php 课程资料: http://mitlab.hit.edu.cn/2010summer/zh_courses.php 1课程内容梳理 Learning to rank for information retrieval 刘铁岩博士 @ 微软亚洲研究院 2010.8.16 上午,在简单的研讨班举办情况介绍、哈工大机器翻译实验室简介、特邀报告演讲人发言、所有与会人员合影之后,便开始了第一门课程: Learning to rank for information retrieval 。这是来自微软亚洲研究院的刘铁岩主讲的,也是四个课程中唯一没有 Project 任务的。 课程首先对机器学习进行了概述。其中重点讲述了监督学习的四个要素:输入空间、输出空间、假设空间、损失函数( loss function )。文档对象通过特征向量表示。其次介绍了传统的排序模型,主要查询依赖模型、查询独立模型。由于在传统的排序模型中手工调整参数是很困难的,因此紧接着课程就讲述机器学习方法在排序中的运用,主要内容涉及主要的学习算法、各种方法的优劣分析、评估方法和数据集。在课程最后,讨论了在学习排序模型中一些前沿的话题,并进行了总结。对于这个课程简单总结一句:利用机器学习的方法训练数据,获取一个性能比较好的排序模型。 Phrase-based statistical machine translation Lars Ahrenberg ,基于短语的统计机器翻译 http://vir.liu.se/~lah/index.en.shtml 课程从基于词语的机器翻译讲起。基于词语的机器翻译有许多缺陷,因此基于短语的机器翻译研究成为热点话题。基于短语的机器翻译通常方法是在词语对( Giza++ )的基础上,运用启发式方法发现短语对。研究表明:基于短语的翻译优于基于词语的翻译;在预处理中融入语言学知识例如tagger、parser等对翻译系统性能是有帮助的 课程中有提到 Factored translation ,对我来说是比较新的概念。一般的翻译模型是遵循 Word-Lemma-POS 模式,而 Factored 模型则 Lemma -POS-Word 模式,即首先翻译 lemma ,其次翻译 POS 词性类别,最后从 lemma 和 POS 词类中生成Word。使用 Factored translation models 主要依据是:词语的统计信息大量出现在 lemma 层次,许多语言中的名词短语可以在 POS 中捕获,在训练数据中不能观察到的形式可以通过对词语的某些组成部分的分析获得。 课程中介绍了 Moses 系统,最后的 project 要求使用中英平行语料,基于 Moses 开发一个统计翻译平台。 Generation of referring expressions(GRE):the state of art Kees Van Deemer , 指称表达式生成- GRE http://www.csd.abdn.ac.uk/~kvdeemte/ 在课程的第一环节, Deemter 教授花了一部分时间讲述 GRE 到底在怎么一回事。我的理解就是:对于一个给定的场景或对象,设计一个算法用最准确的属性恰当地描述场景或对象,并且这种描述能识别唯一的一个场景或对象。简言之,这个算法需要找到最好的描述该对象的属性或者识别出该对象的独有属性。 在具体的 指称表达式 生成 (GRE) 的算法设计中,当前的方法和技术一般都是限定在某一个领域中,枚举对象的所有属性,通过类似查找筛选的方法(判断对象是否具有该属性,属性是否在领域类别中及属性的取值等),搜索并返回能够表征某个对象的最佳属性。 在 GRE 评估中,基本思想是:计算机器生成的 referring expression 和人类生成的 referring expression 之间的相似度,比较相似度差异,从而判断算法的优劣。实质是计算机生成的文本与人类生成的文本之间的相似度比较。 GRE 对领域非常依赖的,准确率也有待提高。 Project 部分则要求设计一个算法,实现简单的 GRE 。 Information retrieval Daqing He http://www.sis.pitt.edu/~daqing/ 何老师的课程更为基础,基本覆盖信息检索的基本理论,并对多语言信息存取的基本理论进行了讲述。 信息检索的基本理论主要包括:文档和查询处理(预处理、标引、存储)、检索或匹配模型(向量空间模型、语言模型)、相关反馈及其评估,其中穿插有一些检索评估度量方法和标准(准确率、召回率、评价准确率等)。 何老师的课程中以英文作为语种,因此 文档预处理部分 的内容就围绕如何对英文文档进行预处理展开讨论,主要涉及 tokenization 、 lemmatization 、 stemming 等预处理方法。 文档标引部分 主要讲述倒排索引的构成、如何构建等问题;同时详细讨论倒排索引文件的存储结构和方法,如哈希表、 B- 树等。对于大规模的文档处理来说,速度显得尤为重要,因此一个好的索引文件存取结构显得非常必要。 查询处理 的一般步骤包括:停用词去除、词干还原、名词短语识别、查询词语的权重计算等。 检索模型部分中,首先讲述了布尔模型的基本概念,布尔模型类似一个 hard classifier ,比较简单但缺陷也较多;其次讨论了特征权重的计算方案,包括 tf 、 df 、 tf-idf 、似然频率权重等;重点对向量空间模型的理论进行了系统的讲解,涉及向量构成、向量表示、余弦相似度、归一化等基本内容。信息检索中的统计语言模型可以看作是一个生成模型,即生成某种语言文本的一种概率机制。 相关反馈的运用基于这样的事实:用户的查询并不总是接近其真实的信息需要,而通过对检索到的相关或不相关文档的分析能够生成更符合用户信息需要的查询。相关反馈的信息可以从用户的检索行为中获取(显式相关反馈),也可将检索系统返回的前 N 个文档作为相关文档(即伪相关反馈)。通过对相关反馈信息的运用,可以对查询特征项重新赋予权重,或进行查询扩展,或应用到其他的检索任务中如跨语言信息检索。相关反馈的评估中以 TREC 作为引子,详述了当前一些常用的评估方法和标准。 在多语言的信息存取中,首先讲述跨语言信息检索的三大关键问题:翻译什么,如何获取翻译知识,怎样使用翻译知识;其次是多语言信息存在的一些关键问题。在多语言信息存取中,课程内容的一个理念是:多语言信息存取应该是以用户为中心的,是人机交互的一个动态的过程。因此为了支持交互的多语言信息处理,解决跨语言信息检索中出现的翻译歧义问题,相关反馈( relevance feedback )的应用显得尤为重要。查询扩展则作为查询、查询翻译、相关反馈等环节的联系纽带,通过查询扩展,相关反馈的信息得以利用,从而有效解决了部分查询翻译歧义的问题。机器翻译是解决多语言信息存取中跨语言查询翻译的另一个方法。 Project 部分要求在 Lucene 基础上,对于给定的文档集合,建立索引并存储;利用 Trec 做一个评估测试;基于 Lucene 设计一个简单的语言模型;使用 Google Tranlate 搭建一个多语言的 Lucene ;使用在线词典构建多语言的 Lucene 。 2 Project 所有的 project 都是在一个实验室进行的,其中以机器翻译组尤为活跃。大概是由于举办单位哈工大有个机器翻译课题组,因而多了许多高手,讨论的比较激烈。相比之下, referring expression 生成小组人数有些单薄,不到 10 个人;而信息检索小组虽然人数居多,但因为何老师走了,没有辅导人员,也显得有些落寞,不过有一部分人还是完成了部分任务。 3 感想 研讨班的四门课程讲的都是一些基本问题,关注理论前沿的内容较少!总体而言,对我来说,帮助仍然是很大的,尤其是信息检索的内容。虽然有些理论和概念早有看过,但总有些问题理解不够深入,听过何老师课程,解决了很多疑惑。遗憾的是,因为 project 部分要求用 Java 实现,而我本身是不懂 Java 语言的事实上,如果能完成 project 中的任务,对我的帮助会更大。 另外,不得不提的是,英语的听说水平实在是有待提高。刚开始听课,感觉就是在听天书,偶尔才能听懂几个单词。好在有讲义,听几句,翻讲义,再加上猜,对基本内容有了基本了解。看来,以后的学习中,对于英语的听说学习应该强化。 考虑一下在时间和能力允许的情况下,学习下 Java 语言,因为有很多开源的工具用 Java 编写,如果会一点,一定大有裨益。关注机器学习在信息检索、文本挖掘领域的应用,貌似机器学习的方法很管用。 后记 其实,整个 2.5 天的课程中,几乎每天我都有不同程度的瞌睡,我也是相当郁闷,在学校再怎么熬夜也不会如此困,何况在哈尔滨那几日都是 10:30 左右睡觉。也许是感冒的缘故,也许是有太大压力吧,抑或是其它,哎,这个问题真是个谜 在哈尔滨的几天,真的没有出过汗,凉爽,绝佳的避暑胜地但是如果像我一样,感冒了,就不 OK 了,那只能是杯具 回南京时,在北京转车,有 5 个小时的候车时间,偷空去了天安门,赶上看降旗了,也算不枉路过北京。不过郁闷的是,其实没看清楚,仪式没开始的时候,觉得自己站的位置还不错,应该可以看清楚,可是等快开始的时候,前面突然多了 N 多比自己高的,举着相机,无语

HELP--private high school tuition in the U.S.
zuojun 2010-5-21 15:02
Suddenly, I feel like a frog at the bottom of a deep well... I know private high schools in the U.S. can cost a lot. Punahou is a great school, and its annual tuition goes UP every year--it will be USD 17,800 for the school year of 2010-2011. (If it were NOT for the poor economy, it could have been USD 500 more.) What I never heard of, until today, is that a private school in the U.S. can charge tuition differently, that is, charging an international student more than twice of its "normal tuition." I am talking about tuition alone, not including boarding, etc. If someone knows a private school that does this, that is, charging international students much more, could you please leave me a link in the comment area? Maybe this is the way the U.S. can try to get out of its recession (in addition to rejecting Chinese for their visa applications)?

东北大学2009 CTCST之行
josh 2009-7-24 14:01
2009/7/14-2009/7/23 辽宁沈阳,东北大学,2009 CTCST Summer School。 http://www.a-center.neu.edu.cn/summerschool/ 2009/7/14 下午17:43我和郑毅、薛斌强两位师兄乘坐k188踏上了去沈阳的征程。 本来自己还带了《Roving mars》、《Mathematical mind-benders》、红宝书,和T. M、A andW control、S signal identification的论文,但一上火车,便和本来不大熟识的二位师兄大侃特侃起来。 跟旁边的人共同语言不多,所以基本上都是我们三人之间的谈话,谈话内容也基本上没有脱离实验室这个大框架。从谈话中逐渐对二位师兄有了更多的认识。薛师兄是山东人,谈话中谈论自己较少,主要是对我们谈论的内容进行评论;郑师兄是吉林人,经历十分丰富, http://zhengyi.yo2.cn/about-myself ,一路上都是他在主宰我们的谈话。不知不觉过了3个小时,我“闭五行”(《逝去的武林》)回忆了一下我们的谈话内容,发现这3个小时改变了许多自己多年来固守的看法。 我隐约觉得,这趟旅程将会改变我很多。 2009/7/15 由于是硬座,所以我们睡觉时已经是今天凌晨了。 薛师兄有声音睡不着觉,我和郑师兄基本上没受什么影响。半睡半醒中多次看到薛师兄换位置和姿势,他被折磨得不清。 人和人差别在有些方面可能非常大,我见过很多有声音睡不着觉的人,也见过很多有光睡不着觉的人,而我则属于有声音有光站着都能睡着的人。 睡醒之后我们又继续海侃,其间有很长一段时间是我和郑师兄开薛师兄的玩笑,开玩笑的过程标志着我们三人已经混熟。 北京之前是我到达过的祖国领土最北的地方。过了北京,二位师兄看了看我带的T. M的文章。郑师兄半小时就找到了我半年才找到的T. M文章的毛病,包括其刚刚发表。但师兄们告诉我每篇文章都有错误,所以不要把精力放在挑错上,而应该做些建设性的东西出来。 越往北,火车上的“小沈阳”腔调的人越多。我一直非常喜欢东北话,听东北人说话对我来说是一种享受。 夜里十一点我们到了沈阳,之后直奔东北大学招待所。正好我们三人一个房间。躺在单人床上伸展四肢真爽。 2009/7/16 第一天是秦泗钊的课,和郑毅师兄的方向比较一致。 在上课之前,我们去东大食堂吃免费的早餐。半年没见到馒头、热豆浆、北方的咸菜、大油条这次可以随便吃,真是莫大的幸福。吃的过程中一直提醒自己一定只能吃七分饱以免犯困,毕竟自己是来学习的。但终究没有把持的住:一根大油条、两个馒头、一个鸡蛋、一碗小米粥、两碗豆浆,再加上所有的咸菜都吃了一遍。要不是第一天上课的新鲜感刺激着我,估计吃完回招待所睡觉了。 至于二位师兄吃的情况,由于涉及个人隐私,故略去。但还是忍不住想说:我吃完之后又等了他们10+分钟。 秦泗钊是国际上在过程控制领域把控制理论与控制工程结合地比较好的大牛级人物。主要从事预测控制、半导体制造过程的故障诊断与优化控制、系统辨识理论、故障诊断与控制系统性能评估等方面的工作。 他今天讲的是数据驱动的故障检测与诊断。我一直对数据驱动这几个字十分敏感。我理解的数据驱动是do somethingwithout modeling。我一直认为传统频域系统理论和时域的DMC之所以成功正是因为他们是数据驱动-控制直接来自系统的输入输出。秦今天讲的内容是非常符合直觉的。我所认为的符合直觉是把他的方法应用到最简单的情况,比如一个传感器测量一组或两组数据,或者两个传感器测量一组或两组数据时,他的方法就是最明显正确的做法。然后将其数学化,便是秦的理论。 郑毅师兄对其甚是崇拜,也梦想去读他的博士后。 这次他主要讲基于数据的异常工况诊断,之前我对这一课题了解甚少,一天6小时的课下来,基本上抓住了它的框架和结构。我们坐在最前排,郑师兄用他的数码相机把ppt拍了下来。我和薛师兄其间各打盹n次和m次。 后来聊天时,郑师兄聊到他曾经帮一个朋友用matlab做过故障诊断,说的简单了就是一个传感器对某一个量测两次,如何判断传感器有无故障。我和他首先想到的做法是求两次测量值的差。他朋友最终采用的做法是求方差。我们想了想,求方差的做法就是秦的数据驱动方法在单传感器时的做法。 我在觉得自己已经理解了讲课者的思路时往往会奖励自己一下,可以随便走走神。我于是开始走神想关于sinusoid的事情。发现我之前的理解存在很多漏洞与不清楚之处,想想它毕竟与控制关系不大。于是决定放弃。但我在听课时走神思考问题效率确实不低。 晚上没课,我们把校园逛了一逛。东大校园整体比较旧,高楼不多,还有很多1957年标志的老房子。本来打算在各个校门照张像,但他们的校门实在太旧,最终也没照一张像。买了些沈阳特产“不老林糖”。晚上回到招待所,郑师兄分析程序,薛师兄看电视,我则发呆,想了一些长久以来困扰我的人生和学习问题。当然,大部分时间我们还是在聊天和相互开玩笑。 我趴在床上写了些东西。关于预测未来,关于五年计划,关于理论、物理与数学,关于模型,关于工程与理论的问题、方法、应用和实践、拓展,关于lyapunov和模型的减法。关于控制与人的五官四肢。 补充:中午和下午的饭菜也是甚合吾意,大概有六样菜,大多是东北菜,有馒头有米(东北大米!),全部随便吃。我们基本上是按轮吃,每轮吃的大概是一顿饭的量。我们三合起来大概吃来七八轮。 2009/7/17 上课第二天。 王宏的Advanced Filtering design and its applications to FDI。 王宏在FDI方面开创性工作是非常好的,但感觉他的后续研究有点“做习题”的味道。不过,这也让我们听课变得容易许多。只需要认认真真听他讲自己最初的工作,其后的思路基本一致。 晚上高中同学、现在东北大学自动化系得程志勇请我搓了一顿东北菜,感觉相当爽。我们聊了许多高中、大学和现在的事,后来又到他宿舍去了一趟,住宿条件相当不错。 十点之前我赶回去洗澡。睡觉前郑师兄看文章,薛师兄看电视,我则继续想那些长久以来困扰我的人生和学习问题。我们的聊天和玩笑内容也越来越出格。 2009/7/18 我们参观了综合楼七楼的工业过程综合自动化重点实验室。东北大学的自动化系中过程控制占绝对的的主导地位。工业过程综合自动化重点实验室的硬件与软件配置足以说明这一点。而更重要的是,该实验室许多项目都是与工厂直接挂钩,并且在实际工程中得以应用的。最让我印象深刻的是其中两个获得国家科技发明二等奖的项目,其创造的经济效益不可估量。 随后我们参观了自动化研究中心实验室,中心实验平台甚是壮观。该实验室拥有自己的期刊室、工程设计室,甚至还有健身房、茶歇、卡拉 OK ,墙上挂着各种绘画和摄影作品。 中午我们在校园里照了几张相,下午便去张学良的张氏帅府参观。张学良的“爱人如己”的亲笔题词算是此行最大的收获。 参观过程中我们和其他学校的学生逐渐熟识起来。他们来自北航、山大、东南、北大、华科、清华。通过不长时间的接触,发现大家对一些问题的理解深度基本一致,知识的广度也差不多。 今天毕竟玩了一整天,到了晚上精神仍然很饱满,竟然想通了好几个问题。关于控制与未来科技,关于模型与科学技术,关于计算机时代的控制,关于量子计算机与控制,关于网络与控制回路。 2009/7/19 今天是孟庆虎教授讲 Stable Adaptive Control of Robotic Manipulators with Medical Applications 。 孟 教授是我本科大学山东大学控制学院的院长。他开篇先介绍了一下香港中文大学的情况,以吸引我们之中的有志者去那里求学或研究。 我一次表都没看。 孟 教授的几句话我记忆犹新,大意如下: “如果一个领域 98% 的人在做某个方向,你就别去做了。并不是说做不出好结果,而恰恰相反,他们基本上肯定能作出好结果。你应该做那 2% 的人,或者在那个好结果的基础上再做,或者直接去应用那个好结果。” 其间还听到一个北大的学生谈到中科院和北大的硕士培养制度-论文宁缺毋“烂”以及中国控制学者在国外的形象-timedelay and LMI。 晚上我又去找程志勇聊天。他告诉了我许多东北大学教授和学生的具体情况,有的与表面上我们看到的有很多差别。 2009/7/20 今天是最后一天。林威教授的 A Nonsmooth Feedback Framework for the Control of Nonlinear Systems 。 林 教授在这方面做出了很多很好的结果。但无奈自己数学基础不好,只是能够勉强跟上他的思路。当他讲推导过程时,我双眼发呆地盯着反馈控制器的最终形式,试图记住其“样子”。我现在还在想,很多时候,控制器的最终形式比推导过程简单多了(如 DMC )。 后来我开始做这学期的总结。想通了一件非常重要的事-为生为乐为特长应分开。于是决定写??的彩虹。 晚上我们逛了东大旁边的一个公园。郑师兄想去跟一些中老年人跳舞最终未遂。薛师兄盯着一对踢毽子的老年夫妇看了足足 10 分钟,不停的感慨那是他想要的生活。 2009/7/21 早上我们三个一起看电视剧。好久没看过电视剧了,在薛师兄的带领下,我们随便找一个电视剧看,直到广告,然后立即换另外一个电视剧。由于没头没尾,我很难看下去。薛师兄兴致勃勃,郑师兄不时地对电视剧中的某种现象进行一下评论,而我则只寻找其中有关爱情的部分,学两招,然后想象如何应用。这时,二位师兄会指出其中的不合适之处,我以之为根据改进。 中午 12 : 49 的火车。硬卧。 上车之前买了 2009/7 的《 Scientific American 》。在车上读不下去。草草读了关于日食的一篇和 Daniel Tammet 的一篇,之后又读了中文版加上去的一篇。有所得,不多。 火车上邻座的问我们是干吗的,我开玩笑说薛师兄是厨师。其实薛师兄不仅长得有厨师相,他的梦想之一就是当厨师。那个邻座的就开始说他的某某朋友在哪里当厨师赚多少钱。之后每当我们谈及一个话题,那个邻座的就说他的某某朋友在哪里做我们话题中的那个行当赚多少钱。 晚上马腾打来电话说河马(昵称) 23 号结婚 , 我是肯定赶不回去了。在家的高中同学只有 10 余个。估计河马也知道大家暑假都很忙,所以提前两天才通知。我跟程志勇、蔡吉吉、杜斌说好 8 月初回去再补。 郑师兄的三句话我一直记得,“我现在都不编程了,而你们抢着去学编程”,和“唯唯诺诺、犹犹豫豫的性格不应该在我们身上”,“因该相互帮助”。 2009/7/22 今天有 500 年一遇的日全食,整个长江流域都可以看到。但我们在回上海的火车上。 我从 9 : 20 就守在火车窗边,一直到 9 : 50 都没有感觉到阴雨绵绵的天空有什么变化。上海也在下雨,在上海的同学说他们只是在日食时感觉到黑夜突然来临。 500 年一遇的日全食就这样过去。我想:我大概一定不可能活到 500 年以后了吧。 后来和师兄讨论起我现在正在研究的问题“ ST in NCS ”,基本上找到了上半年自己思路的不清楚之处和下一步可能的方向。二位师兄均不鼓励我继续朝这一方向研究下去。我现在仍没有想清楚这个问题。 终于回到了闷热的上海。 薛师兄直接买了 29 号回济南的火车票。郑师兄回学校。我去了上海书城。 去上海书城之前我吃了大娘水饺,花了九块钱吃了三两南方的三鲜水饺,附赠水饺汤和南方的蒜和醋,回到了南方的饮食风格中。 到了书城,发现了一本 John Von Neumann 文集《 The role of mathematics in the sciences and in society 》,本来想买,但最终决定回来走图书馆 - 网上下载 - 当当路线。之后买了大四在济南新华书店和上次来书城就想买的《太极拳xx》。花 50 块买了《 Flight stability and automatic control 》最能体现这次沈阳之行给我带来的变化。对《 Einstein: His Life and Universe 》失去兴趣也体现了这一变化。 回到宿舍,与李长礼聊了最近的学习和生活。他的老板是做实际项目的,给的暑假只有 10+ ,他现在基本上每天都往徐汇校区奔,在他老板的实验室一直干到晚上。而我们做理论的则每日无所事事,只能以看论文、想论文和倒论文打发日子。谁能说孰好孰劣?于是每当下一届的师弟让我推荐导师时我总是回避。 又开始了我的上半身锻炼计划。 2009/7/23 今日,算是我的沈阳之行正式结束。 我又回到了宿舍、食堂、实验室、图书馆的生活之中。 早上下了一些这期《 Scientific American 》上推荐的一些书,《 Born on a blue day 》、《 Fantastic reality 》 , 还有我按计划下的《 The Drunkard's Walk: How Randomness Rules our Lives 》。之后在书店发现了一本《 The power of less 》。 下午在实验室一直想写点什么。本来搜集了很多 John Von Neumann 、 Richard Phillips Feynman 、 Stephen Wolfram 的介绍和文章写到博客里,但一想那毕竟是转载别人的东西,于是转而写我一直想写的东大之行。 账目: 吃饭: 100 买东西: 50 回头买书: 80 想不起来干吗的: 50
