Hugging Face has published a step-by-step guide on setting up a custom leaderboard using their platform. The example uses Vectara's hallucination leaderboard as a case study, showing how to create and manage a leaderboard from scratch. The process involves creating a dataset, training a model, and configuring the leaderboard settings in Hugging Face's dashboard. --- Why it matters: This matters because it provides AI engineers with practical knowledge on how to set up custom evaluation metrics for their models, which is essential for comparing performance across different tasks and datasets.
