MemAgent: Learning to Manage Heterogeneous Memory Providers for LLM Agents

Yongxian Wei, Yilin Zhao, Runxi Cheng +5

Current agents remain largely stateless across tasks, limiting their ability to continually improve from prior interactions and making memory essential for long-horizon agentic beh…

Closed-Form Spectral Regularization for Multi-Task Model Merging

Yongxian Wei, Runxi Cheng, Xingxuan Zhang +4

Model merging combines several independently fine-tuned experts into a single multi-task model without any training data, reducing the storage, serving, and decentralized-developme…

Memory Grafting: Scaling Language Model Pre-training via Offline Conditional Memory

Runxi Cheng, Yuchen Guan, Yongxian Wei +7

Scaling conditional memory offers a promising way to increase language-model capacity, but existing methods such as Engram learn large memory tables from scratch during pre-trainin…

Spectral Characterization and Mitigation of Sequential Knowledge Editing Collapse

Chi Zhang, Mengqi Zhang, Xiaotian Ye +5

Sequential knowledge editing in large language models often causes catastrophic collapse of the model's general abilities, especially for parameter-modifying methods. Existing appr…
