Radar HRRP Data Augmentation Using CVAE with Extended Latent Space Distribution

2022 IEEE 5th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC) (2021)

Wenxiang Zhang Youquan Lin Long Zhuang Jie Guo

In this paper, we propose a variational autoencoder (VAE) based generative model with particular regard to the aspect angle sensitivity of the radar HRRP data of maritime vessels, and conduct high-resolution range profile (HRRP) data augmentation experiments to improve the recognition performance. Specifically, we train the extended conditional Variational auto-encoder (ECVAE) model to reconstruction data, and consider the latent space distribution of the sample as a more general multidimensional posterior Gaussian distribution. Discrete or continuous labels can be input to the model. Design a periodic latent distribution to deal with periodic labels. Use Kullback-Leibler (KL) divergence to evaluate the similarity of the distribution and reconstruct data with the latent space distribution which making the dimension as low as possible. Experiments based on MNIST data and measured vessels HRRP data show that the ECVAE model can augment the data of samples to improve recognition Performance, in especial in the case of a small number of data samples.

Climate Change and Drought Events in the Geochemical Records of the Lacustrine Deposits in the Southeastern Tibetan Plateau

PLoS ONE (2016)

Wenxiang Zhang Ming Qing-zhong Zhengtao Shi Jie Niu Huai Su

Lacustrine deposits at the margin of the southeastern Tibetan Plateau (SETP) are sensitive indicators for the evolution of the southwest Asian monsoon (SWAM) during the Quaternary. Thus, they can provide insight into the Quaternary climatic history and their relationship with global climatic changes. The results of the geochemical analysis of the Xiaozhongdian Basin section at the SETP suggest that SiO2 had the highest content of the major elements followed by Al2O3. The order of the abundance of the major elements was generally as follows: SiO2>Al2O3>Fe2O3>CaO>MgO>K2O>TiO2>Na2O>MnO2. The geochemical proxies, such as chemical index of alteration (CIA), the index of compositional variability (ICV) and (CaO+K2O+Na2O)/Al2O3, indicate the weak chemical weathering and the aridification of the margin of the SETP during the Heinrich events. In addition, the aridification of the SETP during the Heinrich events may be closely related to the cold signals transmitted from the high latitudes of the North Atlantic to the TP, and the effect caused the cooling effect to be very strong on the TP as a result of the upper-level westerly jet stream and then reduced the suction action associated with the SWAM, thus accelerating the drying rate of Xiaozhongdian Basin, which was amplifying the degree of drought in Heinrich events.
