Researchers have developed a new framework called Holistic Multivariance Decomposition (HMD) for hyperspectral image classification. This novel approach aims to improve accuracy and efficiency by capturing complex spatio-spectral interdependencies without the high computational cost of traditional convolutional neural networks (CNNs). The HMD framework, including its HMD-0, HMD-1, and HMD-2 variants, is designed as a differentiable neural network layer that can be optimized end-to-end. Evaluations on benchmark datasets show that HMD layers outperform classical tensor decomposition methods like Tucker and Tensor Train, while offering comparable generalization and stability to 2D and 3D-CNNs with significantly fewer parameters.
