摘要：
This paper proposes a model-free approach for spectral unmixing based on a convolutional neural network. It is evaluated using sample data sets and compared with methods based on the linear mixing model. Furthermore, methods to ensure physical plausibility of the estimated abundances are presented. This approach involves output layers that enforce non-negativity and the sum-to-one constraint.
