Seismic Data Interpolation based on Denoising Diffusion Implicit Models with Resampling

no code implementations9 Jul 2023 Xiaoli Wei, Chunxia Zhang, Hongtao Wang, Chengli Tan, Deng Xiong, Baisong Jiang, Jiangshe Zhang, Sang-Woon Kim

The model training is established on the denoising diffusion probabilistic model, where U-Net is equipped with the multi-head self-attention to match the noise in each step.

Federated Coordinate Descent for Privacy-Preserving Multiparty Linear Regression

no code implementations16 Sep 2022 Xinlin Leng, Chenxu Li, Weifeng Xu, Yuyan Sun, Hongtao Wang

We show that the FCD scheme fills the gap of multiparty secure Coordinate Descent methods and is applicable for general linear regressions, including linear, ridge and lasso regressions.

MSSPN: Automatic First Arrival Picking using Multi-Stage Segmentation Picking Network

no code implementations7 Sep 2022 Hongtao Wang, Jiangshe Zhang, Xiaoli Wei, Chunxia Zhang, Zhenbo Guo, Li Long, Yicheng Wang

Besides, since the gather data is a set of signals which are greatly different from the natural images, it is difficult for the current method to solve the FAT picking problem in case of a low Signal to Noise Ratio (SNR).

Linking Attention-Based Multiscale CNN With Dynamical GCN for Driving Fatigue Detection

no code implementations IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, VOL. 70, 2021 2020 Hongtao Wang, Linfeng Xu, Anastasios Bezerianos, Chuangquan Chen, Zhiguo Zhang

Finally, the critical brain regions and connections for driving fatigue detection were investigated through the dynamically learned adjacency matrix. Index Terms— Attention-based multiscale convolutional neural network (CNN), driving fatigue, dynamical graph convolution network (GCN), electroencephalography (EEG), spatiotemporalstructure.
