Huanxuan Liao 廖桓萱

I am a second-year PhD student in Pattern Recognition and Intelligent Systems at the University of Chinese Academy of Sciences (UCAS) and the Institute of Automation, Chinese Academy of Sciences (CASIA), advised by Prof. Shizhu He and Prof. Kang Liu. Previously, I earned my B.Eng. from North China Electric Power University (NCEPU) (2023), working with Prof. Min Shi and Prof. Yun Ju.

Data & Pretraining Long-Context Models Continual Adaptation Long-Horizon Agents

Better data & architectures for stronger models and longer horizons.

Research statement · Long-Horizon Adaptive Intelligence

I study foundation models for long-horizon adaptive intelligence: models that use growing contexts effectively, acquire and retain reusable capabilities across evolving tasks, and act reliably over extended interactions.

  • Long-Context Data & Model Co-Design: long-context data curation and synthesis, length- and capability-aware mixtures, scalable pretraining and mid-training, efficient attention, KV-cache optimization, and architectures to jointly improve capability, scalability, and efficiency (Awesome-LCLM, HyCo2, SparK, ResAdapt, AllocEmbed).
  • Knowledge & Continual Adaptation: mechanisms for acquiring, transferring, internalizing, and updating knowledge and capabilities across evolving tasks, while balancing plasticity, retention, and generalization (TAGI, SHIP, DyPRAG, AAG, NesyCD, SKIntern, SpaRTA).
  • Agent Learning & Self-Improvement: persistent memory, long-horizon decision-making, and learning from interaction and feedback, toward agents that verifiably refine their memory, policies, and learning procedures (CITI, KATE, BuPO, Tool-RL-Box, OPERATE, Distill Yourself, Scientist's Last Exam).
