I'm a master’s student at the Institute of Automation, Chinese Academy of Sciences, advised by Prof. Shizhu He. I received my B.E. from UESTC.
My research focuses on language models and AI agents, especially how agents can improve through closed-loop learning and become better collaborators for real users. My interests include:
I have worked on large-scale optimization of foundation models to improve how they interact and collaborate with users.

SAEScientist-Bench evaluates whether AI agents can recover semantically specified SAE features using restricted activation probes and validates them through held-out activation and causal steering.
PostTrainBench⁰ evaluates whether LLM agents can improve frozen models through gradient-free, score-only search under fixed compute and time budgets.
SWE-Touch injects validated, task-conflicting user edits into live coding-agent trajectories to evaluate state awareness and adaptation in shared workspaces.
DSRL warms up models with negative-sample reinforcement on unconditional P(y), then reincarnates the policy into conditional P(y|x) reinforcement learning.
BuPO first optimizes a lower-layer internal policy to rebuild foundational reasoning, then switches to full-model reinforcement learning for refinement.
Mode selection is a harder early-exit problem because it must choose a reasoning mode before observing any question-specific reasoning trajectory.
Cross-scale parametric knowledge transfer requires alignment, yet behavioral and structural differences create neural incompatibility that destabilizes both PostPKT and PrePKT.
DyPRAG trains a lightweight translator to convert retrieved documents into dynamic LoRA parameters, enhancing LLM knowledge efficiently at test time.
RobustPT dynamically disentangles modality-specific prompts before softly aligning them, reducing channel bias and improving robustness when vision or language is missing.
G-SAP builds refined evidence graphs, derives structure-aware prompts for frozen language models, and performs heterogeneous graph-text message passing for commonsense reasoning.
