Improved Bounds for Private and Robust Alignment

Wenqian Weng, Yi He, Xingyu Zhou

In this paper, we study the private and robust alignment of language models from a theoretical perspective by establishing upper bounds on the suboptimality gap in both offline and…

Learning-Based Automated Adversarial Red-Teaming for Robustness Evaluation of Large Language Models

Zhang Wei, Hanxuan Chen, Peilu Hu +19

Red-teaming is becoming a central part of large language model (LLM) safety evaluation, yet current practice still relies heavily on expert-written prompts or fixed benchmark suite…

AOI: Context-Aware Multi-Agent Operations via Dynamic Scheduling and Hierarchical Memory Compression

Zishan Bai, Hanxuan Chen, Jiayi Gu +9

Cloud-native systems have made operational work both more powerful and harder to automate: incidents unfold across microservices, logs and metrics arrive faster than operators can…

CoT-X: An Adaptive Framework for Cross-Model Chain-of-Thought Transfer and Optimization

Ziqian Bi, Yinzhi Wang, Tianyang Wang +6

Long Chain-of-Thought (CoT) traces can improve reasoning accuracy, but repeatedly generating them is costly for smaller or latency-constrained language models. This paper studies a…

SquarePO: Differentially Private and Robust -Preference Optimization in Offline Direct Alignment

Xingyu Zhou, Yulian Wu, Wenqian Weng +1

In this paper, we theoretically study the offline alignment of language models with human preference feedback, under both preference label corruption and privacy protections. To th…
