Background Debiased SAR Target Recognition via Causal Interventional Regularizer

no code implementations30 Aug 2023 Hongwei Dong, Fangzhou Han, Lingyu Si, Wenwen Qiang, Lamei Zhang

Based on the constructed SCM, we propose a causal intervention based regularization method to eliminate the negative impact of background on feature semantic learning and achieve background debiased SAR-ATR.

Unsupervised Deep Representation Learning and Few-Shot Classification of PolSAR Images

no code implementations27 Jun 2020 Lamei Zhang, Siyu Zhang, Bin Zou, Hongwei Dong

To handle this problem, in this paper, learning transferrable representations from unlabeled PolSAR data through convolutional architectures is explored for the first time.

Band Attention Convolutional Networks For Hyperspectral Image Classification

no code implementations11 Jun 2019 Hongwei Dong, Lamei Zhang, Bin Zou

Unlike most of deep learning methods used in HSIs, the band attention module which is customized according to the characteristics of hyperspectral images is embedded in the ordinary CNNs for better performance.

Efficiently utilizing complex-valued PolSAR image data via a multi-task deep learning framework

no code implementations24 Mar 2019 Lamei Zhang, Hongwei Dong, Bin Zou

To solve the above problem, the objective of this paper is to develop a tailored CNN framework for PolSAR image classification, which can be implemented from two aspects: Seeking a better form of PolSAR data as the input of CNNs and building matched CNN architectures based on the proposed input form.
