URL: kulbir-singh-ahluwalia.com/cs498gc/fa25/presentations.html For: CS498GC 4-credit students Format: 15-minute presentation + 5-minute Q&A on assigned SLAM paper

TL;DR - Key Requirements:

  • Slides due: Exactly 1 week before presentation date

Wed, Dec 3 Tue, Nov 26
Fri, Dec 5 Thu, Nov 28
Wed, Dec 10 Tue, Dec 3

What We Want You to Learn (and Show):

  • Methodology & Architecture - explain the system diagram and motivate each design choice
  • Novelty - what’s truly new and why it matters
  • Limitations - be specific and evidence-based (failure cases, assumptions, compute/data constraints)
  • Improvements - concrete ideas to address those limitations

Prof. Girish’s Suggested Questions for a Compelling Talk:

  1. Why is it important?
  2. Why is it hard?
  3. How is it novel?
  4. Why does it work?

Suggested Slide Outline (Target: 15 minutes):

  • Problem & motivation (tie explicitly to mobile robotics/SLAM)
  • Definitions/background (only what’s needed to follow the method)
  • System diagram & architecture (reasoning for each component/choice)
  • Method details: inputs/outputs, training objectives/losses (write the equations), and why each term exists
  • Results: metrics, baselines, ablations; 2-3 key takeaways
