Insight Gained from Migrating a Machine Learning Model to Intelligence Processing Units

no code implementations16 Apr 2024 Hieu Le, Zhenhua He, Mai Le, Dhruva K. Chakravorty, Lisa M. Perez, Akhil Chilumuru, Yan Yao, Jiefu Chen

The discoveries in this paper show that Intelligence Processing Units (IPUs) offer a viable accelerator alternative to GPUs for machine learning (ML) applications within the fields of materials science and battery research.

First arrival picking using U-net with Lovasz loss and nearest point picking method

no code implementations6 Apr 2021 Pengyu Yuan, Wenyi Hu, Xuqing Wu, Jiefu Chen, Hien Van Nguyen

Similar to \cite{wu2019semi}, we use U-net to perform the segmentation as it is proven to be state-of-the-art in many image segmentation tasks.

Progressive transfer learning for low frequency data prediction in full waveform inversion

no code implementations20 Dec 2019 Wenyi Hu, Yuchen Jin, Xuqing Wu, Jiefu Chen

For the purpose of effective suppression of the cycle-skipping phenomenon in full waveform inversion (FWI), we developed a Deep Neural Network (DNN) approach to predict the absent low-frequency components by exploiting the implicit relation connecting the low-frequency and high-frequency data through the subsurface geological and geophysical properties.
