RLAR: An Agentic Reward System for Multi-task Reinforcement Learning on Large Language Models

Andrew Zhuoer Feng, Cunxiang Wang, Bosi Wen +4

Large language model alignment via reinforcement learning depends critically on reward function quality. However, static, domain-specific reward models are often costly to train an…

RAVEL: Reasoning Agents for Validating and Evaluating LLM Text Synthesis

Andrew Zhuoer Feng, Cunxiang Wang, Yu Luo +9

Large Language Models have evolved from single-round generators into long-horizon agents, capable of complex text synthesis scenarios. However, current evaluation frameworks lack t…

TraceSIR: A Multi-Agent Framework for Structured Analysis and Reporting of Agentic Execution Traces

Shu-Xun Yang, Cunxiang Wang, Haoke Zhang +12

Agentic systems augment large language models with external tools and iterative decision making, enabling complex tasks such as deep research, function calling, and coding. However…

DVD: A Robust Method for Detecting Variant Contamination in Large Language Model Evaluation

Renzhao Liang, Jingru Chen, Bo Jia +7

Evaluating large language models (LLMs) is increasingly confounded by \emph{variant contamination}: the training corpus contains semantically equivalent yet lexically or syntactica…

UDA: Unsupervised Debiasing Alignment for Pair-wise LLM-as-a-Judge

Yang Zhang, Cunxiang Wang, Lindong Wu +4

Pairwise evaluation of Large Language Models (LLMs) is a common paradigm, but it is prone to preference bias, where judges systematically favor certain outputs, such as their own.…

Deep Literature Survey Automation with an Iterative Workflow

Hongbo Zhang, Han Cui, Yidong Wang +6

Automatic literature survey generation has attracted increasing attention, yet most existing systems follow a one-shot paradigm, where a large set of papers is retrieved at once an…
