My name is Oleg Ovcharenko and I am Solutions Architect for energy at NVIDIA. I am broadly interested in deep learning, HPC and numerical methods.

Recent research

  • Direct domain adaptation through reciprocal linear transformations

    We proposed a general method for domain adaptation which blends features from source and target datasets by a set of linear operations such a cross-correlation and convolution. We explore the viability of the approach by transferring knowledge from training on gray-scale MNIST dataset to colored MNIST-M dataset. ArXiv, 2021

  • Deep Learning for Seismic Data Reconstruction: Opportunities and Challenges

    Research project from my internship in CGG, Crawley, UK. Under supervision of Song Hou I explored benefits and pitfalls of using GANs for seismic data reconstruction. In the nutsell, high perceptual realism of reconstructed seismic data is not sufficient for real-world application. Physics also should be constrained. First EAGE Digitalization Conference and Exhibition, Nov 2020

  • Extrapolating low-frequency prestack land data with deep learning

    In synthetic framework we explore capability of a simple neural network to reconstruct low-frequency components of land data. SEG Technical Program Expanded Abstracts 2020

  • Style transfer for generation of realistically textured subsurface models

    We apply an iterative style transfer approach from image processing to produce realistically textured subsurface models based on synthetic prior models. These realistically textured models to be used in training datasets for machine learning applications in geophysics. Presented in Sep 2019, on SEG Annual meeting in San Antonio, USA
