Dual-graph convolutional network based on band attention and sparse constraint for hyperspectral band selection

作者:

Highlights:

• An improved graph convolutional network is proposed for band selection.

• Band-based and sample-based graphs are built with spatial and spectral information.

• Design soft-shifting optimization strategy to overcome the optimization problem.

• Mini batches of labeled and unlabeled samples are used for graph construction.
