DOI: 10.1109/tgrs.2021.3077833
Abstract: This work derives a novel unsupervised neural network-based scheme for unmixing hyperspectral pixels. A novel autoencoder structure was combined with a kernelization layer, mapping the mixed pixels in a higher dimensional space for easier separability,… read more here.
