Domain Generalization with Small Data

no code implementations9 Feb 2024 Kecheng Chen, Elena Gal, Hong Yan, Haoliang Li

In this work, we propose to tackle the problem of domain generalization in the context of \textit{insufficient samples}.

AutoAssign+: Automatic Shared Embedding Assignment in Streaming Recommendation

no code implementations14 Aug 2023 Ziru Liu, Kecheng Chen, Fengyi Song, Bo Chen, Xiangyu Zhao, Huifeng Guo, Ruiming Tang

In the domain of streaming recommender systems, conventional methods for addressing new user IDs or item IDs typically involve assigning initial ID embeddings randomly.

Deformation Monitoring of Tunnel using Phase-based Motion Magnification and Optical Flow

no code implementations15 Jun 2023 Kecheng Chen, Hiroshi Kogi, Kenichi Soga

Traditional vision-based monitoring can directly capture an extensive range of motion but cannot separate the tunnel's vibration and deformation mode.

Robust Cross-domain CT Image Reconstruction via Bayesian Noise Uncertainty Alignment

no code implementations26 Feb 2023 Kecheng Chen, Haoliang Li, Renjie Wan, Hong Yan

Under this probabilistic framework, we propose to alleviate the noise distribution shifts between source and target domains via implicit noise modeling schemes in the latent space and image space, respectively.

GCN-MIF: Graph Convolutional Network with Multi-Information Fusion for Low-dose CT Denoising

3 code implementations15 May 2021 Kecheng Chen, Jiayu Sun, Jiang Shen, Jixiang Luo, Xinyu Zhang, Xuelin Pan, Dongsheng Wu, Yue Zhao, Miguel Bento, Yazhou Ren, Xiaorong Pu

To address this issue, we propose a novel graph convolutional network-based LDCT denoising model, namely GCN-MIF, to explicitly perform multi-information fusion for denoising purpose.

Lesion-Inspired Denoising Network: Connecting Medical Image Denoising and Lesion Detection

no code implementations18 Apr 2021 Kecheng Chen, Kun Long, Yazhou Ren, Jiayu Sun, Xiaorong Pu

To this end, we propose a play-and-plug medical image denoising framework, namely Lesion-Inspired Denoising Network (LIDnet), to collaboratively improve both denoising performance and detection accuracy of denoised medical images.
