Part I: Reading a Scientific Paper 可视计算研究中心 2 VISUAL COMPUTING RESEARCH CENTER
Why read scientific papers? I read papers because of: • The Content: • Looking for new ideas or new proof techniques to write a new paper • You can use the raw data in your own research • The Topic: • What are the new directions in my field or learning a new topic • The Authors: • Find supervisors or collaboration 可视计算研究中心 3 VISUAL COMPUTING RESEARCH CENTER
Structure of Scientific Papers Title 可视计算研究中心 4 VISUAL COMPUTING RESEARCH CENTER
Title and authors • Title is very descriptive and states the main finding. • Order of authors is important. Example:
Abstract • Usually consists of ◦ Purpose or rationale of study ( why they did it ) ◦ Methodology ( how they did it ) ◦ Results ( what they found ) • Get a general idea • You can decide if the paper is worth reading based upon this. 可视计算研究中心 6 VISUAL COMPUTING RESEARCH CENTER
Introduction • Serve for two purposes: • Create readers’ interest in the subject • Provide them with enough background information to understand the paper • Accomplish this by leading readers ： • what is known about the topic • what is not known • what questions the authors asked and answered 可视计算研究中心 7 VISUAL COMPUTING RESEARCH CENTER
Methods • Should be detailed enough for another scientist to replicate the work. • Often you can skim over them before the results. • You will need to flip back to them often to clarify how experiment was done. • Sample number? • Conditions • In reality, often compressed and you may need to look up another paper that is referenced for more detail.
Results • The results describes the outcome of the experiments that were done to answer the questions. • With each experiment/figure you should be able to explain : • the basic procedure • the results • the conclusion • criticisms
Conclusions • Conclude the main findings of the paper • Show current limitations • Pose directions for future work 可视计算研究中心 10 VISUAL COMPUTING RESEARCH CENTER
Tips on reading a paper • Digital copy: figures • Print copy: notes • Multi-pass reading • Read Start early • … 可视计算研究中心 11 VISUAL COMPUTING RESEARCH CENTER
Digital copy • Look carefully at the figures, diagrams and other illustrations in the paper ◦ The fastest way to get an idea of what’s going on in the paper ◦ The best way to search words 可视计算研究中心 12 VISUAL COMPUTING RESEARCH CENTER
Print copy • Make notes when you read ◦ Scribble notes responding in context to the formulas, figures, and text • Underline key points the authors make • Restate unclear points in your own words • Write questions or criticisms down • Draw connections to other methods and problems you know about • … ◦ This keeps your attention focused and makes you engage with the paper 可视计算研究中心 13 VISUAL COMPUTING RESEARCH CENTER

The first pass 可视计算研究中心 15 VISUAL COMPUTING RESEARCH CENTER
The second pass 可视计算研究中心 16 VISUAL COMPUTING RESEARCH CENTER
The third pass • What can we learn from the paper? • What are the good ideas in this paper? • Do these ideas have other applications or extensions that the authors might not have thought of? • Can they be generalized further? • Are there possible improvements that might make important practical differences? • If you were going to start doing research from this paper, what would be the next thing you would do? • … 可视计算研究中心 17 VISUAL COMPUTING RESEARCH CENTER

Start early • Leave enough time that if your attention wanders • You can put the paper down and pick it up again when you're in a better reading mood • This is better than trying to force yourself through it on a deadline When you are starting out in a new area, it may take you hours to read a paper thoroughly. That's okay. It's worth spending that much time to really understand a good or foundational paper. 可视计算研究中心 19 VISUAL COMPUTING RESEARCH CENTER
Part II: Presenting a Scientific Paper 可视计算研究中心 20 VISUAL COMPUTING RESEARCH CENTER
Before You Start • Know your topic • (Be sure you have understood the paper) • Know your audience • (Your talk must take the audience into account) • Know your goals • (What are the expectations of the audience?) • Know your limits • (How much time will be needed?) 可视计算研究中心 21 VISUAL COMPUTING RESEARCH CENTER
Organize Your Talk • Identify the key ideas • (Make sure that all the key ideas of the paper are in your talk) • Do not go into too many details • (Ignore the equations and focus on the essentials) • Use a top-down approach • (starting wide, finishing narrow) 可视计算研究中心 22 VISUAL COMPUTING RESEARCH CENTER
Organize Your Talk • Introduction • Define the problem • Discuss previous work • Emphasize the contribution of the paper • Body • List major results and explain the meaning • Give some examples • Technicalities • Present some experimental results • Conclusion • Remind the main results • Explain your opinions on the paper 可视计算研究中心 VISUAL COMPUTING RESEARCH CENTER
Slides • The simpler, the better! • (do not put the whole sentences you want to say on slides) • Use colors! • (but don’t exaggerate!) • Use pictures • (one picture is worth thousands of words) • One slide = 1–3 minutes (average) • (think about timing) 可视计算研究中心 24 VISUAL COMPUTING RESEARCH CENTER
Speaking • Speak slowly and loud • Avoid reading from a prepared text • Use less formal, with shorter sentences, and use more signposts • Check all animations with the sound on • Maintain eye contact with the audience • Control you timing 可视计算研究中心 25 VISUAL COMPUTING RESEARCH CENTER
