From Static Personal Values to Contextualized Personalization: Bayesian Personalized Value Alignment for LLMs

Read the original on arXiv AI →

The paper introduces BaCVA, a Bayesian Context-aware personalized Value Alignment method for large language models. It treats personal values as priors and context-dependent preferences as posteriors, estimating contextual value salience from normative responses and using a dual-view personalization module to infer posterior preferences. Experiments show BaCVA outperforms strong baselines, offering more accurate and data‑efficient personalized value alignment.

Synthetic Interaction Data for Scalable Personalization in Large Language Models

arXiv:2602. 12394v2 Announce Type: replace Abstract: Personalized prompting offers large opportunities for deploying large language models (LLMs) to diverse users, yet existing prompt optimization methods primarily focus on task-level optimization while largely overlooking user-specific preferences and latent constraints of individual users.

Re2A: Situated Conversational Recommendation via Rubric-based Preference Reasoning and Alignment

Re2A is a new framework for situated conversational recommendation that models user interactions within shared physical environments. It introduces rubric-based preference reasoning to explicitly capture user preferences from dialogue history and scene context, and a preference-conditioned optimization to align generated responses with both user satisfaction and situational consistency. Experiments on two SCR datasets show that Re2A outperforms existing methods, providing more precise and context-aware recommendations.

GUIDE: Generative Utility Inference and Decision Engine

GUIDE is a large‑language‑model driven architecture that elicits and infers human user preferences through conversational Bayesian adaptive sampling and symbolic rule‑based learning. It extends adaptive sampling to a wide range of elicitation questions via a flexible type system and initializes domain‑specific preference models using symbolic representations of world knowledge. In simulated investment portfolio optimization, GUIDE outperforms prior methods, LLM‑only baselines, and its own ablated variants by improving cold‑start performance and reducing recommendation regret during early interactions.
