如何作网络通信领域的研究

  1. 1. 如何做网络通信领域的研究? Yanglet 上海交通大学 2011年12月1日
  2. 2. 来源与参考0. 2010年和2011年,本实验室组会和973联合实验室组会; 2010年6~8月973论文培训; 2011年10~11月SIGCOMM、MobiCom论文集训;参考1. 倪明选 , 香港科技大学讲座教授 上海交通大学致远讲习教授; 《如何做应用型研究?》2. Qiang Yang, 香港科技大学讲座教授 人工智能; 《The Road from Research IDEAs to Papers》3. 冯丹, 华中科技大学 计算机学院副院长 存储; 《科技论文写作》5. Jennifer Rexford, Princeton University 《The Networking Philosopher’s Problem》 CCR, 2011-06-034. 伍民友 , 上海交通大学 电院计算系 教授; 《做研究与怎样做研究》
  3. 3. 提纲 什么是科学研究? 理论研究与应用型研究 网络通信领域的科学研究• 网络领域的重要会议与期刊• 如何搜索论文• 如何阅读论文? 什么样的课题可以做,有哪些研究类型? 如何去找一个好的研究题目? ― 几位师兄的例子• Sensor Networks:赵铭辰、孔令和• VANETs:朱弘恣、李智、吴宇晨 如何把一个研究题目做好? 如何把一篇文章写好? 关于论文审稿 结论
  4. 4. 什么是研究(research)?研究是 Re (repeat) + search 吗?资料收集是研究吗?事实的发现(fact discovery)是研究吗?研究是创造新的知识研究并没有一个简单的模式 ― 做研究的方法会因人而异或因事而异 ― 不同的人做研究的方法也可能不同理论型研究:Theoretical Research应用型研究:Applied Research 4
  5. 5. Theoretical or Applied Research ?网络通信领域与物理,数学等领域是不同的― 理论物理,实验物理,计算物理― 纯数学,应用数学,计算数学网络通信领域是应用科学,也有理论问题,也需理论研究基础什么是网络通信领域的理论研究?― Algorithms, NP-complete, graph theory, game theory, information theory, coding theory, queuing theory, etc.― 研究结果不一定有直接应用价值 • 例如电子系王新兵老师:Network Capacity & Connectivity网络通信领域基本上是应用型科学研究― 研究的结果可能有实际的应用价值― 需要的支撑技术成熟了吗?― 解决的问题有意义吗?― 解决问题的方法可行吗? • 解决问题的方法常需要理论研究的基础(如:NP) 5
  6. 6. 关于科学研究 John Day (参与ARPANET的设计)计算机科学与其他科学领域的最大区别是:我们构建自己所测量的! Mark Twain《Life on the Mississippi》科学使人着迷:在其中我们可以通过对少量事实进行研究而获得大量的猜想! 金海老师计算机学科没有科学问题,因为计算机领域的所有科学问题都是数学问题!
  7. 7. 网络领域的重要会议与期刊博士毕业相关:根据上海交大计算机系与中国计算机学会评级国际会议― 毕业: SIGCOMM、MobiCom、INFOCOM、ICDCS、IPDPS、(网络安全:S&P, STOC) 信息处理、知识发现与数据库:SIGKDD、SIGMETRICS、 SIGMOD、VLDB、SIGIR、ICDE― Rank 1: SIGCOMM、MobiCom― Rank 2: NSDI、ICNP、MobiHoc、SenSys、PerCom、IMC、CoNEXT 、IPSN― Rank 3: SECON、WCNC、ICC、Globecom顶级期刊― 毕业:ToN、JSAC、ToIT、TPDS、TMC、TWC、ToSN 、JPDC、 Trans. on (Communications, Computers, Computer Systems)、 Computer Networks重要信息:接收率、截稿日期与收录篇数(大致)― 15~18% INFOCOM~7月30日(290/1600) ICDCS~12月15日(80/580)― 12% SIGCOMM~1月27日(33/270) MobiCom~3月9日(30/270)― 35~45% GlobeCom~3月15日(1100/3000) ICC、WCNC~9月20日(1000,550)
  8. 8. 要读多少有关文章?要读什么有关文章?Top conferences or workshops first ― ACM Sigcomm, ACM/IEEE Mobicom, IEEE Infocom ― IEEE ICNP, ACM MobiHoc , IEEE ICDCSSecond tier conferences only for reference ― IEEE Globecom, ICC,WCNCAvoid bad conferencesLook for some known researchers web sitesFor me ― Dina Katabi @ MIT, Lili Qiu & Yin Zhang @UTCS, Peter Steenkiste@CMU; ― Sachin Katii@Stanford, Tian He@ Minnesota ; ― Qian Zhang@HKUST, Yunhao Liu@Tsing Hua;Read journal papers only it has not been published else where, orwhen it contains more detailed and complete treatment.
  9. 9. 如何搜索论文?网络通信领域的顶级会议的主页
  10. 10. 如何搜索论文?网络通信领域的顶级会议的主页跟踪10位学术牛人的主页― Lili Qiu @UTCS
  11. 11. 如何搜索论文?网络通信领域的顶级会议的主页跟踪10位学术牛人的主页― Lili Qiu @UTCS搜索引擎― Google Scholar, Microsoft Academic Search;― Google;― IEEE Elec. Library Search.
  12. 12. 如何读论文?问题― What― Why • 为什么要解决这个问题?解决的问题有意义吗?为什么别人没想到这个问题?解决方案― 方法合理吗?方法够好吗?评估的方法合理吗?别人有类似的方法吗?文章的罩门在那里?― 用了那些假设? 什么条件下不能适用?还可以做什么― 改良, 对基于模型的文章改良,往往不是好工作― 基于此: 在此之上,顺势思维(掌握新方法和工具时)― 与此类似: 与此平行,发散思维(了解新特性和新问题时)― 由此需要: 在此之下,逆向思维(对问题有了更加本质的认识)例子:李智ICDCS 2011,朱弘恣INFOCOM 2010 Mini:基于此和与此类似; MobiCom这几年收录的多天线: 与此平行 在此之下,往往是SIGCOMM论文的风格,喜欢做基础性研究,有高屋建瓴的姿态!
  13. 13. 研究的四个种类New problem and new solution ― This comes rarely, perhaps something you could only wish, once a life-time experience (such as Shannon theory)Old problem and old solution ― Plenty of out there under the category of “Yet another paper on … ”New problem and old solution/Old problem and new solution ― You may target the above two ― Examples: new routing algorithms, a new branch of sub-problems Problem Old New Old Method New

  21. 21. 如何去找一个好的研究题目?Drink a beer, relax, and ideas will come to youThe ideas fall from the sky!Understanding the existing work, build upon thatincrementally ― A thorough understanding of those is the basisIdeas in most cases come from the deep understanding of asubject, and possess of broad knowledge ― This is not a technical training, i.e., this is not about solving a differential equations ― This is about relating them to real world problems ― This is about providing new insight beyond known ― This is about your creativity! 21
  22. 22. 如何把一个课题做好?如何评价好― 问题新、解决方法新(Novelty)― 研究深入(Depth),如:新问题  NP  近似算法的近似度  模拟/仿真/实现― 解决方案(Soundness)问题― What:把问题定义想清楚,讲清楚― Why:把问题要解决的目标目的讲清楚解决方案 ― 如果问题太大,“分治法”在研究中,可以给一些合理的假设(也是罩门所在)你知道可能的解决方法吗?方法够实际吗?有类似的解决方法吗?与其他的方法有比较吗?多讲讲― 实验室师兄弟们,室友,老板,来访教授多听听― 组会上其他同学的研究思路― 网络通信领域其他学者的做法(如,你所跟踪的牛人)

Introduction ― What is the problem ― Why is it not already solved, or other solutions are inferior in one or more important ways ― Why is our solution worth considering and why is it superior in some way ― How the rest of the paper is structured2. Related Work ― What other efforts to solve this problem exist and why do they solve it less well than we do ― What other efforts to solve related problems exist which are relevant to our effort, and why are they less good than our solution for this problem3. Our Design / Implementation ― What we (will do, did): Our Solution ― How our solution works : A basic overview is good! ― The detailed logic of our work.

  26. 26. Conference PapersStart earlier for a conference submissionWhich conference to submit?Deadline is the best drive for making progressWhat make a good paper: content and writing!Clear, convincing, simple and good English ― This is a never-ending optimization process, do this within the time and page limitsReview process 5/30 rule ― 5 minutes - Abstract, introduction, figure and conclusion ― 30 minutes – understand 90% of the paperAbout Conference Review ― 3‾6 Reviewer ― 1‾5 Points ― Given independently, then those reviewer decide the paper to go: • Accept (555,554,544,444 一定收;345,344,335,334不确定,看运气!) • Discuss at TPC meeting (333,345,344,335,334,255,245,235,145等等) • Reject (111, 123等)
  27. 27. Journal PapersA good conference paper (10%-25% acceptance rate) can besubmitted to a journal, with 30% new resultsReport more complete and focused resultsWhich journal to submit the paper?Give yourself a deadlineBe patient with the long review and re-reviewAt the earlier stage of one’s career, don’t quit if asked formajor revision ― But don’t do seemingly impossible
  28. 28. Review ProcessLow acceptance rate ― Typical in many CSE conferencesReviewers are potential competitors ― Try to convince them and don’t give them excuses to kill the paperReviewers are very busy ― Try to make their job easierEnglish is not our strengthDon’t try your luck, it won’t work!
  29. 29. What Does a Reviewer Look for?New problem or new solution?Are the main results significant?Is the paper technically correct?Does the paper provide a fair assessment of itsstrength and limitation?Is the paper clearly written, thus accessible togeneral readers?Are the references adequate?Is the paper appropriate for conference/journal?…
  30. 30. 关于审稿 The Evil ReviewerHow long do they take to reject your paper? If (Abstract: Search for “In this paper…”=OK) then { If(Introduction: Search for “In this paper…”=OK) then{ (If(Theoretical/Experimental results: Search for key theorems or key charts = OK) then{ If(Related Work: Search for key=OK) then If(English = OK) then(accept pile) Else reject
  31. 31. 论文撰写 A Reviewer’s Rejection CommentsThis paper attempts to explain the success of Naive Bayes classifiersby showing that…Unfortunately, this paper was extremely difficult to follow. ― In fact, it took several readings before I even understood the papers basic claims. ― The paper should have stated, at the beginning, that it is focusing on the representational (as opposed to learnability) issue: … ― It would also have been useful to connect this notation with something practical--for example, …The arguments and proofs were difficult to follow. ― They would probably have been easier if the paper had first outlined their structure, before giving the details. ……
  32. 32. 总结 《一个英国主教的墓志铭》“我年少时,意气风发,踌躇满志,当时曾想要改变世界。 但当我年事渐长,阅历增多,我发觉自己无力改变世界, 于是缩小了范围,决定先改变我的国家。 但这个目标还是太大了。哥们,这不就是“修身,齐家,治国平天 接着,我步入了中年,无奈之时, 下”,有木有!!! 我将试图改变的对象锁定在最亲密的家人身上。 但天不遂愿,他们个个还是维持原样。 当我垂垂老矣,我终于顿悟了一件事, 我应该先改变自己用以身作则的方式影响家人。 若我能先当家人的榜样,也许下一步就能改变我的国家, 再后来我甚至可能改变整个世界,谁知道呢?”
