2010年到2011年间138个ieee国际会议被否决
今天在网上无意中看到的消息，希望你参加的会议没有在这张列表里。
作者之前与ieee签署的版权转让自动失效，如果作者愿意可以提交获取ieee的电子版版权无效的声明的申请。会议的注册费能否退还要视会议主办方而定。
ps: ieee维护的会议列表可以在这里查询到（2011年8月22日更新），但是ieee cs好像有些会议在这里也不一定能看到。
你查过GB/T 11457 了吗？
同行交流起来术语的含义一定要统一规范，要不然会造成相互间理解起来困难，这点在写作学术性论文时特别的重要。信息技术方面，我国是有自己的标准GB/T 11457，对于外文词汇的翻译以及定义有明确的说明。在写作论文时，如果有些词汇翻译或者概念的定义拿捏的不准，最好先参考一下这个标准。最新的标准好像是2006版。
some links about statistical tools
The reason i explore the statistical tools is related to my research project. Our lab has a project about applying sensor networks to agriculture. To help agronomists have better understanding about their plants, we employ sensor networks to collect environmental parameters of crops grown in green houses and crop fields. Although we got a great amount of data, the data is not ready for use. We have to preprocess the raw data to eliminate or correct the false ones, which usually requires statistical computation over the datasets. After simple survey, I’ve decided to give R a little try.

[转载]我眼中的中国科研：一个中科院退学博士生的感想
不知道为什么转载自天涯论文的原文（http://www.tianya.cn/publicforum/content/free/1/1942170.shtml）被删除了。
感兴趣的可以在这里阅读 http://bit.ly/9eECms
对作者的观点持部分保留，但也不能全面否定中国目前的科研，总体来看科研经费多的院校还是要比科研经费少的做的东西好些（或者说做的没有那么烂）。
不过原文被删除这件事情却让觉得有些恐怖，仿佛是回到了1984年……
在我看来，开放性与独立思考的思想是进行科学研究的重要品质，而言语上的自由是开放性与独立性思考的一种体现。在目前中国样的环境下，要想有这两种品质并且能将其付诸于行动并不是一件容易的事情。
推荐一篇关于研究的博文
今天推荐一篇在微软亚洲研究院博客上看到的一篇不错的博文——《我们应该做什么样的研究》
ps: 我对自己的定位，如果还继续准备在学术领域的话，应该是：
第三类，“爱迪生型”，他的研究并不过多关注原理，目的是实用性，而不是发明新知识。
分享一篇做phd的方法论
Dr. Jim Kurose在ACM CoNext Student Workshop上做的keynote”Ten pieces of advice I wish my PhD advisor had given me”，讲稿可以从网上下载。虽然关于如何做phd或者研究的方法论网上已有很多（如MIT AI Lab，贝尔实验室的Richard Hamming……），自己也读过一些，但是每次读这类的文章还是会有新的收获。
比较喜欢里面那副关于solution complexity和time关系曲线图。另外，还有学到了一个新名词least publishable unit (LPU)或者也叫做minimum publishable unit (MPU)。
教育是核心竞争力
今天无意中看到slashdot.org的一则新闻讲的是中国吸引海外人才回国的事情China Luring Scientists Back Home。文章的投递者很为美国的前途担忧，质疑科研部门是否要培养这些未来将会报效祖国的学生。鬼子们下面的跟贴很直白，你可以看出民族主义，或者是大国主义，下面摘录一些我觉得有特色的段落和大家分享：
As alluded in the article, Chinese science remains far behind, especially because of rampant cronyism in academia as well as government. But, if more Chinese students go back, it could damage the US’s technology lead. A large percentage of PhD students in the US are from China. Also, the typical PhD student has their tuition paid for and receives a salary. Does it make sense to invest in their training if they will do their major work elsewhere?"
f the US as a whole isn’t providing a sufficient incentive for these students to remain here and China is, then I’d say that the problem is mostly our doing. Give them a good reason to stay and they most likely will, treat them like crap and they’ll leave.
Brain drain sucks even worse for the people who live in the country the person receiving a PhD emigrated from. For instance, there are more doctors in the born in Ethiopia living in just the Washington, DC area than there are doctors in the entire country of Ethiopia. How does a country recover from such a tremendous brain drain and address major social ills like rampant poverty, famine, and endemic corruption when the very people who might be best able to assist with their own experience and knowledge do not return to their native country because there is nothing to return to and no reasonable job prospects? Why must the US retain as many of their foreign born individuals who received their PhD in the US, when under the right conditions these PhD holders could help their own country far more than any kind of work they do in the US? I’m not suggesting we force these people to return or even expect them to return, especially when there is nothing to return to. But then again I see nothing wrong with ti US offering grants and other forms of aid to underdeveloped countries so that they can improve their situation with respect to development and improve the local economy. This would come with the explicit expectation that these governments spend the money wisely, and steps are taken so that as little money as possible is wasted by corruption. 这位仁兄还是说了句公道话
On the other hand, sending back western educated scientists and engineers to China can’t help but better relations between the east and the west. People accustomed to western culture who have move back to China to fill high paying positions in Chinese academia and industry are much more likely to think well of the west than those who were fully brought up, raised, and educated under the Communist Party of China. (Not to say that relations between China and the west are bad at the moment, they’re probably near as good as they ever have been at the moment). 感觉对中国相当有偏见
That doesn’t have to be the case. When I worked as a Post-Doc in Utrecht, the Netherlands, in 2000, we had a Chinese co-worker who just got his Ph.D. and was working also as a post-doc. He got a letter from the Chinese authorities in which he was invited to come back to China. He was promised a job as a professor at a university there. I don’t remember wether he went there to have a look before he moved, but after he moved we got a heartbreaking email from his wife who told us that this so-called ‘professorship’ didn’t exist, and the authorities had given them room to live in a house together with 9(!) other families. This was a big setback for her, being used to the standard of living here in NL. Her husband had a better job here than he had gotten in China. And of course there was no way this poor guy and his family were allowed to come back to the Netherlands. I wouldn’t be surprised if this happens a lot with Chinese people who are drawn back to China by their government. 不知道这个事情是否属实，除非从事了特殊专业，要不应该可以再次选择的。
It has nothing to do with their education and everything to do with taxpayers money being used (in the form of grants) to pay for that education. But apparently you’re just one of the many billions who think that the US exists solely to be the global sugar daddy. 都扯到美国纳税人了，不过还是有智者存在，下面的回复说：apparently you’re just one of the many billions who think that the US exists solely.
Here’s where I think the main problem actually is: We actually send home some who do want to stay. And that is a true wasted opportunity. I’ve met a couple of very smart people in my days as a grad student that were sent home even though they wanted to stay. Visa expired, couldn’t find a job in time or some other such nonsense. If you have a Ph.D. in Mechanical Engineering, you are not likely to be a drag on society, even if you don’t wind up employed in your first six months out. And now they are in China, Germany, India, or Mexico, working and contributing in those economies and using all the tools and education they got courtesy of Uncle Sam. We should make it easier for them. And yes, I have real people in mind that I am typing about.
I think the whole situation is ironic. Quite often when I hear stories about immigrants with degrees getting jobs in the USA, people go ballistic about how they are stealing Americans’ jobs and depressing wages.When they go back to their home country, people then complain about a brain drain and about how they should make a ‘contribution’ to the country that educated them (never mind that they paid highly inflated tuition and quite often even their graduate education was paid for by moneys outside of the USA + grad students essentially work for $10 an hour – slave wages).So they are damned if they do and damned if they don’t.
I lived in China for one year teaching high school students and one thing I noticed in general while students were brilliant at chemistry, maths, physics, etc. when solving text book problems, many seemed to be struggling with coming up with new concepts, and in some cases applying what they learnt into new areas. Many struggled when told ‘I want x as the end result’ without any explanation of the process to achieve the end result. It seems most of the science study was just pure memorizing of facts and figures. I found the same later on when managing some staff from Asia, although very dedicated and hard working they required additional guidance on what processes to use to achieve a goal. There seemed to be a strong sense of ‘copy wherever possible’ (why re-create it, if somebody already has?) My students had to do ‘school’, ‘city’, and ‘provincial exams’ The complained the provincial exams ‘didn’t allow copying’ Another instance of this was when a foreign professor in Chinese university was fired when failing students for work that had obviously been copied from another source. I think US / Europe still had lead on creativity which can be an important factor when coming up with new solutions / ideas. Not to say the Chinese can’t, and it will be interesting to see how they go, but I don’t think the number of PhD’s alone will decide whether US or China has technology lead. It will also depend on how much further China restricts internet access as the number of internet sites being blocked continues to increase, it certainly frustrates me that even though I have a large network of friends in China working in technology social networking / YouTube continues to be blocked there, and alternatives to access these sites such as proxies / VPN are illegal – and often if detected are blocked. For my friends in China who have studied overseas and since moved back to China they are constantly complaining about fact sites like facebook,twitter, youtube no longer work.
基本摘录了自己感兴趣的内容，读后感就是有些美国在担心自己不再是老大的苦日子。中国和发达国家还是有差距，他们看得清楚，我们也看得清楚。教育以及互联网问题我觉得很重要。如果说互联网的审查是当前中国现有的特殊国情，因为中国还有很多无法分辨是非容易冲动的群众，我在想那么改变这一现状的唯一途径就是从教育出发。这应该是一个渐进的过程，我还是相信随着社会的进步，一代人比一代人在思想上更加趋于开放和温和，最终的社会形态有可能是逐渐的改善，变得更加和谐和具有人文气息。教育工作者任重而道远。
另外向那些同工不同酬的贫困地区的代课教师们致敬！
PS: 我在考虑互联网与信息技术可以在多大程度上改善贫困地区教育的问题，不过教育在一开始更重要的也许是言传身教和耳濡目染。
转一篇很不错的文章缅怀钱老【钱学森最后的忧虑：科技创新人才的培养是大问题】
链接在这里：《程序员》官网，原文出自《人民日报》
文章就不直接拷贝了，读完感觉就像钱老在和你面对面的说话，十分真实，这里仅引用其中给我留下印象深刻的一两段话。
后来我转到加州理工学院，一下子就感觉到它和麻省理工学院很不一样，创新的学风弥漫在整个校园，可以说，整个学校的一个精神就是创新。在这里，你必须想别人没有想到的东西，说别人没有说过的话。拔尖的人才很多，我得和他们竞赛，才能跑在前沿。这里的创新还不能是一般的，迈小步可不行，你很快就会被别人超过。你所想的、做的，要比别人高出一大截才行。那里的学术气氛非常浓厚，学术讨论会十分活跃，互相启发，互相促进。我们现在倒好，一些技术和学术讨论会还互相保密，互相封锁，这不是发展科学的学风。你真的有本事，就不怕别人赶上来。我记得在一次学术讨论会上，我的老师冯·卡门讲了一个非常好的学术思想，美国人叫“goodidea”，这在科学工作中是很重要的。有没有创新，首先就取决于你有没有一个“goodidea”。所以马上就有人说：“卡门教授，你把这么好的思想都讲出来了，就不怕别人超过你？”卡门说：“我不怕，等他赶上我这个想法，我又跑到前面老远去了。”所以我到加州理工学院，一下子脑子就开了窍，以前从来没想到的事，这里全讲到了，讲的内容都是科学发展最前沿的东西，让我大开眼界。
……加州理工学院就有许多这样的大师、这样的怪人，决不随大流，敢于想别人不敢想的，做别人不敢做的。大家都说好的东西，在他看来很一般，没什么。没有这种精神，怎么会有创新！……科学上的创新光靠严密的逻辑思维不行，创新的思想往往开始于形象思维，从大跨度的联想中得到启迪，然后再用严密的逻辑加以验证。
我回国这么多年，感到中国还没有一所这样的学校，都是些一般的，别人说过的才说，没说过的就不敢说，这样是培养不出顶尖帅才的。我们国家应该解决这个问题。你是不是真正的创新，就看是不是敢于研究别人没有研究过的科学前沿问题，而不是别人已经说过的东西我们知道，没有说过的东西，我们就不知道。
除了创新外，我觉得还有坚实的基础，我不知道目前的大学教育为我们的知识打下了多深的地基，当然这里既有教也有学的问题。没有扎实专业基础我想那些创新也可能被叫做不切实际。我觉得创新应该是在高教学质量的前提下需要做的工作，而对于一个从令人想睡觉课堂中走出来对于自己专业领域懵懂的学生来说，我不知道他/她会有什么创新。当然我们有十分优秀的老师，只是还不够多，不够使整个校园的风气为之一变。然而任何事情说起来要比做难得多，只希望我们的教育会越来越好。
研究生论文
从fisher的reader share看到一篇关于电子科大取消硕士学位“发表论文”硬指标的报道，转念想到nwpu的政策……早该取消了，没太大意义，老师们要出版免费，学生们对这word发呆，“写”一些自己都不知道是什么的东西。好像浙大，交大好像很早就取消这个对硕士生毕业的硬性指标，现在加上电子科技大学，看来好的学校总是走在前面的原因就是因为他们勇于改革。我估计硕士生发表论文应该会对学校的排名有一定影响，因为这个是在排名统计中有比重的。因此让学校取消这个硬性规定确实需要些取舍。早点取消吧，节省我们是时间和金钱，虽然可能一些杂志社要关门了。取消硕士生论文发表的硬性要求，提高学位论文质量，我们可以更好的共享知识与资料，而不必让我们在中文期刊数据查询关键词得到百度或者google数量级的搜索结果而还是什么都没找到。
Talking about 搞研究
Quote
偶的仿真程序又跑起来了，跑啊跑…幸好这台电鸟是双核的，让我得以同时在这里发发感慨。李敖大师前些天有段言论正好可以拿来说明我得处境和心情：“过去我曾经疯狂的说，人家跟我开玩笑，说你搞不搞政治啊！我讲了一句粗话，我说女人都搞不完，还搞什么政治啊？那一天我看到夕阳以后啊，我才说还是搞政治吧。”不同的是，他搞的是政治，我搞的是研究，他是得了前列腺疾病，我是把脑门都拍肿了。这样的论调是有点离谱，有点反叛。但是看看手上做的这些事情吧，每天都在喊着发表文章，研究成果要准时保质保量完成，算法中无数遥不可及的假设，费劲心思设计了几个“合适”的性能参数，在Matlab下仿真出“好”曲线，就开始洋洋洒洒千言万语道不尽的写文章宣传，文章只要发了便万事大吉，至于后果，管他谁去设想！佛家言，私心太重了！看着身边师兄师姐找工作，发愁的是数据结构，操作系统，网络编程，数据库，编程语言，人际交往，待人接物哪个都少不了。我并不是赞成都去钻研计算机技术应用和公关技能，而是深深的感觉到研究生学习中研究与实际的脱节。感慨发了一大堆，还得面对现实，事情该怎么做还得怎么做。作为经济不独立，社会无地位的学生我们无法改变任何事，只有在夹缝之中寻求这样或者那样的平衡，这也仅仅是在某种所谓“兴趣”主导下的心理平衡。想来还是要看清楚自己的方向，价值和定位，摸着石头过河，最怕的是石头都摸不到！不说了，生活就像一锅波菜汤，去看程序运行结果了。。。外界诱惑太多，自身又比较浮躁，整个团队也不行，真希望能吃个秤砣铁了心的去做好一件事。。。
