Data Mixing Agent: Learning to Re-weight Domains for Continual Pre-training

Kailai Yang, Xiao Liu, Lei Ji +6

Continual pre-training on small-scale task-specific data is an effective method for improving large language models in new target fields, yet it risks catastrophic forgetting of th…

MemAdapter: Fast Alignment across Agent Memory Paradigms via Generative Subgraph Retrieval

Xin Zhang, Kailai Yang, Chenyue Li +4

Memory mechanism is a core component of LLM-based agents, enabling reasoning and knowledge discovery over long-horizon contexts. Existing agent memory systems are typically designe…

Implicit Graph, Explicit Retrieval: Towards Efficient and Interpretable Long-horizon Memory for Large Language Models

Xin Zhang, Kailai Yang, Hao Li +3

Long-horizon applications increasingly require large language models (LLMs) to answer queries when relevant evidence is sparse and dispersed across very long contexts. Existing mem…

Arg-LLaDA: Argument Summarization via Large Language Diffusion Models and Sufficiency-Aware Refinement

Hao Li, Yizheng Sun, Viktor Schlegel +3

Argument summarization aims to generate concise, structured representations of complex, multi-perspective debates. While recent work has advanced the identification and clustering…
