CISC 879 : Software Support for Multicore Architectures Lecture 8: Overview Effective and Efficient Reading Good and Bad Critical Reviewing How to Write a Paper How to Present a Paper

CISC 879 : Software Support for Multicore Architectures What do I mean by “Read?” Effective and efficient reading Do not waste your time on irrelevant papers Maximize your time on relevant papers The Whys, Whats, and Hows of Reading Critical Reading Essential to writing a “good” critical reviewing

CISC 879 : Software Support for Multicore Architectures Problems with Some Papers Solving problems not applicable to an actual need CS has not adopted Scientific Method Least Publishable Unit (LPU) Never clearly contrasting to related work Hard to Read

CISC 879 : Software Support for Multicore Architectures Questions to Ask What are the motivations? What is solution and how is it evaluated? What is your analysis of problem, solution, and evaluation? What are the major results? Correct, new, clearly presented, worth publishing What are contributions? Are there any questions not answered? Reference:

CISC 879 : Software Support for Multicore Architectures Efficient Reading Preparation Quiet place and note-taking material Read for Breadth Read title and abstract Skim intro, headers, tables, graphs, and conclusions Look for primary contributions Read in Depth Challenge arguments, assumptions, evaluations, and conclusions Fallacy: Must read from beginning to end Reference:

CISC 879 : Software Support for Multicore Architectures Anatomy of Good Review Summary of main points of paper (3 to 5 sentences) Evaluation with regard to validity and significance Evaluation quality of work Overall recommendation and thorough justification Reference: Evaluation of novelty, significance, correctness, readability.

CISC 879 : Software Support for Multicore Architectures Bad Critical Reviewing Seek to find all flaws Criticize paper in a negative way Use words like “Idiot” and “Trash” Criticize paper with little comment After all, they know it’s bad Criticize/accept all papers Be known as person that accepts/rejects everything! Reference:

CISC 879 : Software Support for Multicore Architectures Good Critical Reviewing Can Always be Positive Think face-to-face constructive criticism Consider Recently-Published New Directions Explain your Decision No explanation will carry little weight Decide which paper is best Not which paper least worthy of rejection Reference:

CISC 879 : Software Support for Multicore Architectures Bad Review Example This paper is concerned with blah blah blah. The authors develop a method to automatically generate blah blah blah. The solution is based on genetic algorithms and evolution-based methodology. This is a solid paper with respect to methodology and the experiments performed. My score is relatively low because I am not particularly excited by genetic, evolutionary algorithms. Not a Reasonable Justification!

CISC 879 : Software Support for Multicore Architectures Good Review Example I like this work a lot. There are two things that would substantially improve it: 1) Investigation of the reasons why blah blah blah. Is there room for more improvement here, perhaps combining the two in some way? If not, what does this say about what technique we should apply, if forced to choose? 2) Quantitative evaluation of the predictive power of blah blah blah. You seem to have a lot of the necessary data (ie, you can compare the results of blah blah blah from Fig 1). Starts positive, then suggests how to “substantially improve paper.” Reviewer justifies remark!

CISC 879 : Software Support for Multicore Architectures Lecture 8: Overview Effective and Efficient Reading Good and Bad Critical Reviewing How to Write a Paper How to Present a Paper

CISC 879 : Software Support for Multicore Architectures Getting a Paper Accepted Follow the Rules! paper format, length, on time, etc. Spell and Grammar Check Write, Read, Edit, Repeat (many times!) Have colleagues review Look at good (award) papers as examples After-the-fact outline (check flow of paper)

CISC 879 : Software Support for Multicore Architectures Getting a Paper Accepted Write to the reviewer Quality must be recognized quickly What are contributions? Is paper stimulating? Is paper relevant? Have a planned organization of paper Enough details to reproduce experiments

CISC 879 : Software Support for Multicore Architectures Anatomy of a Good Paper Abstract State the problem and why its important Briefly describe solution Implication of solution Introduction Describe problem and motivate importance Describe solution and significant contributions Describe your solution Convince reader this could solve problem Implementation details

CISC 879 : Software Support for Multicore Architectures Anatomy of a Good Paper Defence of your solution Experimental methodology and results Convince reader you solved problem State reasonable counterexamples Related work Convince reader novelty of your solution Conclusion Summary of results and significance of contributions

CISC 879 : Software Support for Multicore Architectures Icing on the Cake Attention Grabber Sentence Great Introduction! Easy to read More time you spend editing, less time reader has to spend Good looking graphs Can understand (paper) from reading graph captions

CISC 879 : Software Support for Multicore Architectures What is Your Talk is about The Paper = The Beef The Talk = Beef Advertisement Do not confuse the two! Reference:

CISC 879 : Software Support for Multicore Architectures Your Talk is NOT About: To impress your audience with your brainpower To tell them all you know on the topic To present all the technical details Reference:

CISC 879 : Software Support for Multicore Architectures Your audience Have never heard of the topic Just had lunch and ready to nap Reference: Your mission is WAKE THEM UP and make them glad you did.

CISC 879 : Software Support for Multicore Architectures What’s in your Talk Motivation (20%) 2 minutes to engage audience Why should I listen? What is the problem? Why is it an interesting solution? Key Idea (80%) Be specific Organize talk around specific goal Ruthlessly prune everything else! Reference:

CISC 879 : Software Support for Multicore Architectures Tips for a Good Talk Reference: Narrow, deep rather than wide, shallow Avoid shallow overview talks Cut to the chase: technical “meat” Examples are your main weapon! To motivate talk To convey intuition To illustrate key idea

CISC 879 : Software Support for Multicore Architectures What to leave out Reference: Related Work Know it, but don’t elaborate on it Technical Detail Extensive formulas and code Dense slides will put audience to sleep! Present specific aspects; refer to paper for details Do not apologize “I didn’t have time to prepare the talk” “I don’t feel properly prepared to give this talk”

CISC 879 : Software Support for Multicore Architectures Final Tips Reference: Be Enthusiastic Practice Memorize first few sentences Move around, use arms Speak to someone at back of room Identify nodders and speak to them Watch for questions

CISC 879 : Software Support for Multicore Architectures What NOT to Do Reference: Use slides with lots of text Use small fonts Reveal one point at a time Use lots of animation and color Go over your time limit Stand in front of projected material Stand with back to audience Point to laptop
