Dual-Domain Cross-Iteration Squeeze-Excitation Network for Sparse Reconstruction of Brain MRI

1 code implementation5 Oct 2022 Xiongchao Chen, Yoshihisa Shinagawa, Zhigang Peng, Gerardo Hermosillo Valadez

Magnetic resonance imaging (MRI) is one of the most commonly applied tests in neurology and neurosurgery.

ComboNet: Combined 2D & 3D Architecture for Aorta Segmentation

no code implementations9 Jun 2020 Orhan Akal, Zhigang Peng, Gerardo Hermosillo Valadez

In order to maintain precision at the boundary and prevent sparse outliers and leakage, we designed ComboNet.

Imitation Learning of Neural Spatio-Temporal Point Processes

1 code implementation13 Jun 2019 Shixiang Zhu, Shuang Li, Zhigang Peng, Yao Xie

We present a novel Neural Embedding Spatio-Temporal (NEST) point process model for spatio-temporal discrete event data and develop an efficient imitation learning (a type of reinforcement learning) based approach for model fitting.

Deep learning for seismic phase detection and picking in the aftershock zone of 2008 Mw7.9 Wenchuan earthquake

no code implementations18 Jan 2019 Lijun Zhu, Zhigang Peng, James McClellan, Chenyu Li, Dongdong Yao, Zefeng Li, Lihua Fang

In this paper, we present a CNN-based Phase- Identification Classifier (CPIC) designed for phase detection and picking on small to medium sized training datasets.

A multi-channel approach for automatic microseismic event association using RANSAC-based arrival time event clustering(RATEC)

1 code implementation7 Feb 2017 Lijun Zhu, Lindsay Chuang, James H. McClellan, Entao Liu, Zhigang Peng

In the presence of background noise, arrival times picked from a surface microseismic data set usually include a number of false picks that can lead to uncertainty in location estimation.
