Comet recently hosted an online panel featuring AI researchers from Google, Stanford, and Hugging Face, discussing common challenges and strategies in machine learning (ML) projects. The experts emphasized that a clear understanding of the final goal is crucial for successful model deployment, as offline performance does not always translate to online success due to issues like distribution shifts and lack of auxiliary goal alignment. They highlighted the importance of continuous monitoring and adapting models to maintain performance over time, as well as considering production constraints early on to avoid creating overly complex models that fail to make it into production. Additionally, the panel advised against "wishful thinking," where results are interpreted optimistically rather than realistically, especially under tight deadlines.
