IVIU-Net: Implicit Variable Iterative Unrolling Network for Hyperspectral Sparse Unmixing
At present, an emerging technique called the algorithm unrolling approach has attracted wide attention, because it is capable of developing efficient and interpretable layers to eliminate the black-box nature of deep learning (DL).

Nonlinear unmixing of hyperspectral images using a generalized bilinear model [PDF]
Nonlinear models have recently shown interesting properties for spectral unmixing. This paper studies a generalized bilinear model and a hierarchical Bayesian algorithm for unmixing hyperspectral images. The proposed model is a generalization not only of

Hyperspectral Unmixing Via Nonconvex Sparse and Low-Rank Constraint
In recent years, sparse unmixing has attracted significant attention, as it can effectively avoid the bottleneck problems associated with the absence of pure pixels and the estimation of the number of endmembers in hyperspectral scenes.
