DOI: 10.1016/j.neucom.2020.06.098

Abstract: Abstract Data often exists in subspaces embedded within a high-dimensional space. Subspace clustering seeks to group data according to the dimensions relevant to each subspace. This requires the estimation of subspaces as well as the… read more here.

DOI: 10.1109/tgrs.2018.2879681

Abstract: Most applications of radar imagery require processing techniques which achieve one fundamental goal: characterize and detect the constituent scatterers for each pixel in the scene. In this paper, we take a new look at the… read more here.

DOI: 10.1109/tnnls.2025.3528470

Abstract: The self-expressive strategy has shown excellent capabilities in realizing low-dimensional representations of high-dimensional data for subspace clustering algorithms. The existing designs, however, are formulated on the linearization assumptions of the data, neglecting the precise characterization… read more here.

DOI: 10.3233/xst-221262

Abstract: PURPOSE Low-dose computed tomography (LDCT) has promising potential for dose reduction in medical applications, while suffering from low image quality caused by noise. Therefore, it is in urgent need for developing new algorithms to obtain… read more here.
