Focus-Then-Reuse: Fast Adaptation in Visual Perturbation Environments

Jiahui Wang*, Chao Chen*, Jiacheng Xu, Zongzhang Zhang^†, Yang Yu

Neurips 2025 [PDF] [Code]

We propose an object-filter to extract task-relevant information at the object level, enabling rapid cross-domain policy deployment.

Deep Anomaly Detection via Active Anomaly Search

Chao Chen*, Dawei Wang*, Feng Mao, Jiacheng Xu*, Zongzhang Zhang^†, Yang Yu

AAMAS 2024 [PDF] [Code]

We propose an active anomaly searching mechanism based on Reinforcement Learning, achieving competitive performance in semi-supervised anomaly detection tasks.

Focus-Then-Decide: Segmentation-Assisted Reinforcement Learning

Chao Chen*, Jiacheng Xu*, Weijian Liao, Hao Ding, Zongzhang Zhang^†, Yang Yu, Rui Zhao

AAAI 2024 [PDF] [Project] [Code]

We boost the performance of reinforcement learning under visual perturbations by introducing a segmentation model.

Internal Logical Induction for Pixel-Symbolic Reinforcement Learning

Jiacheng Xu, Chao Chen, Fuxiang Zhang, Lei Yuan, Zongzhang Zhang^†, Yang Yu

KDD 2023 [PDF] [Code]

We introduce a novel framework that synergizes deep RL and rule learning to handle hybrid pixel-symbolic inputs, achieving superior performance and transferability.
