  3. Why should you take this class? • Learning new technology trends • Cloud computing, datacenter networks, social networks, network security, etc. • Helping you find an exciting research project • Discussing other cool ideas with your fellow students and the instructor

  4. Who should take this class? • A short answer • Anyone who’s interested in the stuff • But seriously • Have time to read the assigned readings before coming to class • Have time for a course project

  5. Course organization • Meet twice a week • Assigned readings for each class • Lecture or Class presentation • Students may sign up for them • Discussion • The most important/fun part

  6. Course work • Reading assignments • Midterm • A course project • Individual, group of 2~3 • I will provide suggestions • E.g., a cloud application

  7. Grading Policy • Class participation and presentation: 15% • Midterm: 15% • Project: 70%

  8. Break • Introduce yourself • Your expectations

  9. How to read Research papers

  10. Reading papers effectively is challenging • Written in a condensed style • Assuming much prior knowledge • Written for a different purpose than being course materials • You have limited time

  11. Learning how to read papers effectively is important • Life-time long skill of self-learning • New knowledge is likely to show up in research papers

  12. How to read paper effectively • Know what you should get out of the papers • Know where to find them

  13. Structure of a paper • Introduction • Motivation • Outline the solution • Body • Solutions in detail • Evaluation to show the solutions are valid • Conclusion • Recap • Emphasize primary contributions

  14. Questions to answer • What are the motivations for this work? • People problem: broader impact on society • Saved time, increased safety • Technical problem • Why is the people problem difficult? • Why are previous solutions inadequate? •  Research problem: what the paper addresses

  15. Questions to answer • What is the proposed solution? • A hypothesis • Why is it believed to solve the problem • Why is it better than previous solutions • Design and implementation

  16. Questions to answer • What’s the work’s evaluation to the proposed solution • What argument, implementation, and/or experiment shows the solution’s better? • What benefits/problems are identified?

  17. Questions to answer • What is your analysis of the identified problem, solution, and evaluation? • Is it a good idea? Flaws? Controversial? Practical? • What are the contributions? • Insights on the research question, ideas, software, experimental techniques, … • What are the future directions? • What questions are you left with?

  18. Questions to answer • What’s your take-away message? • Try to sum up the paper in one sentence from your own perspective

  19. Answers • Write your own abstract • Or annotate the paper

  20. Let’s answer those questions for the 2nd paper • What are the motivations for this work? • What is the proposed solution? • What’s the work’s evaluation to the proposed solution • What is your analysis of the identified problem, solution, and evaluation? • What are the contributions? • What are the future directions? • What questions are you left with? • What’s your take-away message?

  21. Summary • Course introduction • How to read papers • Next lecture • Above the Clouds: A Berkeley View of Cloud Computing
