Best Practices

Master the art of reproducing research results, contributing to the Papers With Code community, and building an efficient research workflow.

Reproducing Results

One of the most valuable skills in ML is the ability to take a paper and its code and reproduce the claimed results. Here is a systematic approach:

  1. Read the Paper First

    Understand the method, architecture, training details, and evaluation protocol before touching the code. Pay special attention to the appendix and supplementary materials where crucial hyperparameters are often hidden.

  2. Choose the Right Implementation

    If multiple repos are linked, prefer: (1) official author implementations, (2) repos with the most stars and recent activity, (3) repos with clear documentation and README instructions.

  3. Check Dependencies and Environment

    Create a fresh virtual environment. Match the Python, PyTorch/TensorFlow, and CUDA versions specified in the repo. Dependency conflicts are the most common cause of reproduction failure.

  4. Start Small

    Run on a small subset of data first to verify the pipeline works end-to-end before committing to a full training run. Check that loss curves behave as expected.

  5. Compare Intermediate Results

    If the repo provides checkpoints or intermediate metrics, verify your results match at those points before running the full experiment.

💡
Expect some variance: Exact reproduction of results is often impossible due to hardware differences, random seeds, and non-deterministic operations. Results within 1-2% of the paper's claims are generally considered a successful reproduction.

Contributing to Papers With Code

Papers With Code is community-driven. You can contribute by:

  • Linking code to papers: If you find a repo that implements a paper but is not linked, submit the connection
  • Adding benchmark results: Submit your reproduction results to leaderboards
  • Fixing errors: Report or correct incorrect links, results, or descriptions
  • Adding datasets: Submit new datasets with proper metadata and documentation
  • Writing method descriptions: Help explain methods that lack clear descriptions

Building a Research Workflow

Integrate Papers With Code into your daily research process:

Staying Current

  • Check the trending page daily or weekly to see what is gaining traction
  • Subscribe to the newsletter for curated weekly highlights
  • Follow specific tasks or benchmarks relevant to your work
  • Use the API to build custom alerts for papers in your area

Literature Reviews

  • Start from a benchmark leaderboard to find all methods for a specific task
  • Use the methods taxonomy to understand how techniques relate
  • Track the evolution of SOTA over time to identify trends
  • Cross-reference with conference proceedings for peer-reviewed quality

Project Development

  • Identify the current SOTA for your task before starting a project
  • Select well-supported implementations as starting points
  • Use standard datasets and metrics to ensure your results are comparable
  • Submit your results back to leaderboards when you publish

Final tip: Papers With Code is most powerful when used as part of a broader research toolkit. Combine it with arXiv, Semantic Scholar, Google Scholar, and Hugging Face to create a comprehensive view of the ML landscape.
