Select Smarter, Not More: Prompt-Aware Evaluation Scheduling with Submodular Guarantees

Xiaoyu Ma, Yiwen Li, Haoyue Liu +4

Automatic prompt optimization (APO) hinges on the quality of its evaluation signal, yet scoring every prompt candidate on the full training set is prohibitively expensive. Existing…

Adaptive Prompt Structure Factorization: A Framework for Self-Discovering and Optimizing Compositional Prompt Programs

Haoyue Liu, Zhichao Wang, Yongxin Guo +2

Automated prompt optimization is crucial for eliciting reliable reasoning from large language models (LLMs), yet most API-only prompt optimizers iteratively edit monolithic prompts…

PIDP-Attack: Combining Prompt Injection with Database Poisoning Attacks on Retrieval-Augmented Generation Systems

Haozhen Wang, Haoyue Liu, Jionghao Zhu +3

Large Language Models (LLMs) have demonstrated remarkable performance across a wide range of applications. However, their practical deployment is often hindered by issues such as o…

The End of Manual Decoding: Towards Truly End-to-End Language Models

Zhichao Wang, Dongyang Ma, Xinting Huang +6

The "end-to-end" label for LLMs is a misnomer. In practice, they depend on a non-differentiable decoding process that requires laborious, hand-tuning of hyperparameters like temper…

Multi-Physics: A Comprehensive Benchmark for Multimodal LLMs Reasoning on Chinese Multi-Subject Physics Problems

Zhongze Luo, Zhenshuai Yin, Yongxin Guo +3

While multimodal LLMs (MLLMs) demonstrate remarkable reasoning progress, their application in specialized scientific domains like physics reveals significant gaps in current evalua…

Federated Unlearning with Gradient Descent and Conflict Mitigation

Zibin Pan, Zhichao Wang, Chi Li +4

Federated Learning (FL) has received much attention in recent years. However, although clients are not required to share their data in FL, the global model itself can implicitly re…
