DGKAN: Dual-branch Graph Kolmogorov-Arnold Network for Unsupervised Multimodal Change Detection

Tongfei Liu, Jianjian Xu, Tao Lei, Yingbo Wang, Xiaogang Du, Zhiyong Lv

AAAI 2026technical

Multimodal change detection (MCD) has important applications in disaster assessment, but the nonlinear distortion of features and spatial misalignment caused by sensor imaging differences make it difficult to obtain changes through direct comparison. To overcome the above problems, this study aims t

SDAFE: A Dual-filter Stable Diffusion Data Augmentation Method for Facial Expression Recognition

Minghao Zhao, Yifei Chen, Jiahao Lyu, Shuangli Du, Zhiyong Lv, Lin Wang

ICASSP 2025accepted

Facial expressions are a powerful medium for conveying emotions. In facial expression recognition (FER) field, the difficulty of collecting specific expressions often leads to class imbalance in mainstream datasets, significantly reducing the classification accuracy of deep neural networks. To addre…
