Key Points

  • A PhD student in AI/computer vision is unable to reproduce a published paper’s reported baseline accuracy (~77%), consistently achieving only about 73% after multiple runs and careful tuning.
  • They have checked implementation details, preprocessing steps, hyperparameters, and even evaluation protocols and random seeds, and they contacted the paper’s author for missing details but received no response.
  • The student is unsure how to proceed because improving performance seems unjustified when their baseline underperforms the paper’s results.
  • The post asks the community for experience and practical strategies for handling reproducibility gaps, especially when key experimental details are missing or authors are unresponsive.

I’m a PhD student working in AI/computer vision, and I’ve hit a frustrating wall with a project.

My supervisor asked me to improve the accuracy of a published paper. My first step has been to faithfully reproduce their results before trying any modifications. The issue is I can’t even match their reported baseline. The paper reports ~77% accuracy, but after multiple runs and careful tuning, I’m consistently getting around 73%.

I’ve double-checked what I can: implementation details, preprocessing, hyperparameters (as much as they’re described), and even small things like random seeds and evaluation protocols. I also reached out to the paper’s author to clarify parts of the paper not mentioned but haven’t received a response.

At this point, I’m unsure how to proceed. It’s hard to justify “improvements” when my baseline is already below theirs.

Has anyone here dealt with this kind of reproducibility gap? How did you handle it especially when key details might be missing or authors are unresponsive? Any practical advice would be really appreciated.
