Divergence Regulated Encoder Network for Joint Dimensionality Reduction and Classification

1 code implementation31 Dec 2020 Joshua Peeples, Sarah Walker, Connor McCurley, Alina Zare, James Keller, Weihuang Xu

In order to better represent statistical texture information for remote-sensing image classification, in this paper, we investigate performing joint dimensionality reduction and classification using a novel histogram neural network.
