paper presentation

  • What problem is each paper trying to solve?
  • Why should we care about this problem? What challenges does it pose? In 1-2 sentences, what are the previous approaches to solving this problem, if any?
  • At a high level, what approach does this work take to solving the problem?
  • In more detail, what are the key steps in the approach?
  • How do the authors set up the evaluation of their approach? What hypotheses are they trying to verify?
  • What experimental outcomes do the authors find? Are the hypotheses confirmed?
  • What are some weaknesses of the approach, or some directions for future work? Be ready to pose some discussion questions.
