SCOPE: Prompt Evolution for Enhancing Agent Effectiveness

Zehua Pei, Hui-Ling Zhen, Shixiong Kai +4

Large Language Model (LLM) agents are increasingly deployed in environments that generate massive, dynamic contexts. However, a critical bottleneck remains: while agents have acces…

Verilog-Evolve: Feedback-Driven and Skill-Evolving Verilog Generation

Zehua Pei, Hui-Ling Zhen, Yu Zhang +3

Large language models (LLMs) have improved Verilog generation from natural-language specifications, but most pipelines still treat generation as isolated sampling followed by funct…

FocuSFT: Bilevel Optimization for Dilution-Aware Long-Context Fine-Tuning

Zehua Pei, Hui-Ling Zhen, Xianzhi Yu +3

Large language models can now process increasingly long inputs, yet their ability to effectively use information spread across long contexts remains limited. We trace this gap to h…

PreMoE: Proactive Inference for Efficient Mixture-of-Experts

Zehua Pei, Ying Zhang, Hui-Ling Zhen +6

Mixture-of-Experts (MoE) models offer dynamic computation, but are typically deployed as static full-capacity models, missing opportunities for deployment-specific specialization.…

Analytical FFN-to-MoE Restructuring via Activation Pattern Analysis

Zehua Pei, Hui-Ling Zhen, Lancheng Zou +5

Scaling large language models (LLMs) improves performance but significantly increases inference costs, with feed-forward networks (FFNs) consuming the majority of computational res…

MemDLM: Memory-Enhanced DLM Training

Zehua Pei, Hui-Ling Zhen, Weizhe Lin +4

Diffusion Language Models (DLMs) offer attractive advantages over Auto-Regressive (AR) models, such as full-attention parallel decoding and flexible generation. However, standard D…
