FSPO: Few-Shot Optimization of Synthetic Preferences Effectively Personalizes to Real Users

ICLR 2026poster

Effective personalization of LLMs is critical for a broad range of user-interfacing applications such as virtual assistants and content curation. Inspired by the strong in-context capabilities of LLMs, we propose few-shot preference optimization (FSPO), an algorithm for LLM personalization that refr…

Grounding by Trying: LLMs with Reinforcement Learning-Enhanced Retrieval

ICLR 2025poster

The hallucinations of large language models (LLMs) are increasingly mitigated by allowing LLMs to search for information and to ground their answers in real sources. Unfortunately, LLMs often struggle with posing the right search queries, especially when dealing with complex or otherwise indirect to…

RLVF: Learning from Verbal Feedback without Overgeneralization

ICML 2024poster

The diversity of contexts in which large language models (LLMs) are deployed requires the ability to modify or customize default model behaviors to incorporate nuanced requirements and preferences. A convenient interface to specify such model adjustments is high-level verbal feedback, such as “Don’t…
