LayoutAD: Exploring Semantic-Geometric Misalignment Reasoning for Scene Layout Anomaly Detection

Zhichao Zeng, Jiasheng Zhang, Jiyun Sun, Jiangtao Cui, Xiaotian Qiao

CVPR 2026

Visual anomaly detection is vital for quality control applications by identifying deviations from normal patterns. Previous structural or logical anomaly detection methods mainly focus on pixel-level deviations like texture defects and reconstruction errors, ignoring the object-level structural and

Efficient Dialog Policy Learning by Reasoning with Contextual Knowledge

Haodi Zhang, Zhichao Zeng, Keting Lu, Kaishun Wu, Shiqi Zhang

AAAI 2022technical

Goal-oriented dialog policy learning algorithms aim to learn a dialog policy for selecting language actions based on the current dialog state. Deep reinforcement learning methods have been used for dialog policy learning. This work is motivated by the observation that, although dialog is a domain wi…
