Code for the paper: DGSSC: A Deep Generative Spectral-Spatial Classifier for Imbalanced Hyperspectral Imagery.

<div align=center><img src="/image/frameworks.jpg" width="80%" height="80%"></div> Fig. 1: Architecture of the proposed DGSSC for imbalanced hyperspectral imagery. The encoder, decoder, and classifier are trained in an end-to-end fashion, driven by the integrated loss of L<sub>PdRec</sub>, L<sub>mmd</sub>, and L<sub>cls</sub>.

Training and Test Process

Please run the 'main.py' to reproduce the DGSSC results on Lokia dataset.

We have successfully tested it on Ubuntu 16.04 with Tensorflow 1.13.1. Below is the classification result when 1% labeled samples are selected as the training set.
