ID-TAP：面向 LLM 智能体测试时人格化的信息导向对决方法
Bridging Exploration and Persona: Information-Directed Dueling for Test-Time Agent Personalization
AI 导读
ID-TAP 是一个受 IDS 启发的神经对决老虎机框架，用于大规模离散人格空间下的 LLM 智能体测试时人格选择，以候选回复的二元比较作为在线信号。它结合查询条件神经效用模型与轻量 Bradley-Terry 探索器，并通过相似度加权热启动跨相关查询迁移比较证据。在七个用户条件生成基准上，ID-TAP 在固定十轮比较预算内取得所评估基线中最强的综合表现。

Abstract:Effective test-time personalization requires LLM agents to adapt to query-dependent user preferences from lightweight interaction. We study persona selection with binary comparisons between candidate responses as the online signal. We present ID-TAP, a scalable, IDS-inspired neural dueling-bandit framework for large discrete persona spaces. ID-TAP combines a query-conditioned neural utility model with a lightweight Bradley-Terry explorer, and transfers comparison evidence across related queries through similarity-weighted warm starts. The neural model shares statistical strength across queries while preserving query-specific scores, and efficient BT updates score hypothetical challengers. Across seven user-conditioned generation benchmarks under reference- and model-based preference simulators, ID-TAP achieves the strongest aggregate performance among the evaluated baselines within a fixed ten-round comparison budget. These results support information-directed challenger selection as an effective design for test-time persona adaptation.
