"Knowing When Not to Reuse: Conditional Experience Transfer in Autonomous LLM Post-Training" by Tingyun Li , Wenfeng Feng , Weiqing Li , Abudukelimu Wuerkaixi , Guohua Liu , Yuewei Zhang
TLDR:
The text discusses the development of a method called Boundary-Calibrated Intervention Transfer (BCIT) to improve the quality of autonomous post-training in language models. The goal is to selectively reuse past training evidence by considering contextual applicability and running bounded trials to reduce harmful updates and enhance the final model quality. Autonomous systems play a role in proposing updates and training candidates based on evaluation feedback, but a central problem arises in determining which past update evidence remains valid after subsequent training has altered the parent model. BCIT addresses this issue by binding observed effects to their source context, checking applicability conditions, vetoing conflicting candidates, and conducting bounded training trials as necessary. Results show that BCIT leads to fewer harmful updates and achieves higher final-model quality compared to other methods when applied to a large language model across multiple contexts.
