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.

A Dimensional Structure based Knowledge Distillation Method for Cross-Modal Learning

no code implementations28 Jun 2023 Lingyu Si, Hongwei Dong, Wenwen Qiang, Junzhi Yu, Wenlong Zhai, Changwen Zheng, Fanjiang Xu, Fuchun Sun

To address this issue, in this paper, we discover the correlation between feature discriminability and dimensional structure (DS) by analyzing and observing features extracted from simple and hard tasks.

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.
