Attenuating Random Noise in Seismic Data by a Deep Learning Approach

no code implementations28 Oct 2019 Xing Zhao, Ping Lu, Yanyan Zhang, Jianxiong Chen, Xiaoyang Li

In the geophysical field, seismic noise attenuation has been considered as a critical and long-standing problem, especially for the pre-stack data processing.

Enhanced Seismic Imaging with Predictive Neural Networks for Geophysics

no code implementations11 Aug 2019 Ping Lu, Yanyan Zhang, Jianxiong Chen, Yuan Xiao, George Zhao

In addition, in each iteration step, the probability cubes of salt bodies and inclusions inferred from the proposed networks can be used as a regularization term within the FWI forward modelling, which may result in an improved velocity model estimation while the output of seismic migration can be utilized as an input of the 3D neural network for subsequent iterations.

Vector and Line Quantization for Billion-scale Similarity Search on GPUs

1 code implementation2 Jan 2019 Wei Chen, Jincai Chen, Fuhao Zou, Yuan-Fang Li, Ping Lu, Qiang Wang, Wei Zhao

The inverted index structure is amenable to GPU-based implementations, and the state-of-the-art systems such as Faiss are able to exploit the massive parallelism offered by GPUs.
