Code for the paper: Semisupervised Cross-scale Graph Prototypical Network for Hyperspectral Image Classification.

Training and Test Process

Please run the 'main_IP.py' to reproduce the X-GPN results on IndianPines data set. The training samples distribution and the obtained classification map are shown below. We have successfully test it on Ubuntu 16.04 with Tensorflow 1.13.1 and Keras 2.1.5.

Visualization of the feature distribution by t-SNE
