Self-Play Enhancement via Advantage-Weighted Refinement in Online Federated LLM Fine-Tuning with Real-Time Feedback
Two new research papers introduce novel self-play algorithms for fine-tuning large language models without human supervision. The first, TPAW, uses a team-based approach where models compete and collaborate with historical checkpoints, employing adaptive weighting for responses and players to improve stability and efficiency. The second, SPEAR, focuses on online federated fine-tuning with real-time feedback, using advantage-weighted refinement and confidence-weighted unlikelihood to train on contrastive pairs derived from partial feedback, making it efficient for edge devices.
