Improving AI coaching with Gemini using real-world Fitbit data
作者：Justin KhasentinoAnastasiya BelyaevaCory Y. McLean
We created and curated three benchmark datasets to assess large language model (LLM) performance on sleep and fitness tasks ranging from answering expert questions to real-world coaching scenarios. Fine-tuning the Gemini LLM on real-world coaching tasks and self-reported sleep-quality outcomes improved its performance and provided a benchmark for further development.
