S^2MVTC: a Simple yet Efficient Scalable Multi-View Tensor Clustering

1 code implementation14 Mar 2024 Zhen Long, Qiyuan Wang, Yazhou Ren, Yipeng Liu, Ce Zhu

Specifically, we first construct the embedding feature tensor by stacking the embedding features of different views into a tensor and rotating it.

Deep unfolding Network for Hyperspectral Image Super-Resolution with Automatic Exposure Correction

no code implementations14 Mar 2024 Yuan Fang, Yipeng Liu, Jie Chen, Zhen Long, Ao Li, Chong-Yung Chi, Ce Zhu

In recent years, the fusion of high spatial resolution multispectral image (HR-MSI) and low spatial resolution hyperspectral image (LR-HSI) has been recognized as an effective method for HSI super-resolution (HSI-SR).

Multi-view MERA Subspace Clustering

1 code implementation16 May 2023 Zhen Long, Ce Zhu, Jie Chen, Zihan Li, Yazhou Ren, Yipeng Liu

Benefiting from multiple interactions among orthogonal/semi-orthogonal (low-rank) factors, the low-rank MERA has a strong representation power to capture the complex inter/intra-view information in the self-representation tensor.

Adaptively Topological Tensor Network for Multi-view Subspace Clustering

no code implementations1 May 2023 Yipeng Liu, Yingcong Lu, Weiting Ou, Zhen Long, Ce Zhu

Therefore, a pre-defined tensor decomposition may not fully exploit low rank information for a certain dataset, resulting in sub-optimal multi-view clustering performance.

Tucker-O-Minus Decomposition for Multi-view Tensor Subspace Clustering

no code implementations23 Oct 2022 Yingcong Lu, Yipeng Liu, Zhen Long, Zhangxin Chen, Ce Zhu

To alleviate these problems, we propose a new tensor decomposition called Tucker-O-Minus Decomposition (TOMD) for multi-view clustering.
