Helping you find an exciting research project 3. Discussing other cool ideas with your fellow students and the instructor 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 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 Course work Reading assignments Midterm A course project ◦ Individual, group of 2~3 ◦ I will provide suggestions E.g., a cloud application Grading Policy Class participation and presentation: 15% Midterm: 15% Project: 70% Break Introduce yourself Your expectations HOW TO READ RESEARCH PAPERS 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 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 How to read paper effectively 1. Know what you should get out of the papers 2. Know where to find them 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 Questions to answer What are the motivations for this work? 1. ◦ People problem: broader impact on society ◦ Technical problem ◦ Saved time, increased safety Why is the people problem difficult? Why are previous solutions inadequate? Research problem: what the paper addresses Questions to answer What is the proposed solution? 2. ◦ ◦ ◦ ◦ A hypothesis Why is it believed to solve the problem Why is it better than previous solutions Design and implementation Questions to answer What’s the work’s evaluation to the proposed solution 3. ◦ ◦ What argument, implementation, and/or experiment shows the solution’s better? What benefits/problems are identified? Questions to answer What is your analysis of the identified problem, solution, and evaluation? 4. ◦ What are the contributions? 5. ◦ 6. 7. Is it a good idea? Flaws? Controversial? Practical? Insights on the research question, ideas, software, experimental techniques, … What are the future directions? What questions are you left with? Questions to answer What’s your take-away message? 8. ◦ Try to sum up the paper in one sentence from your own perspective Answers Write your own abstract Or annotate the paper Let’s answer those questions for the 2nd paper What are the motivations for this work? 2.
