My name is Oleg Ovcharenko. I am Senior Solutions Architect at NVIDIA, specializing in Generative AI for energy applications. Currently, my interests are in end-to-end training / fine-tuning, and deployment of Large Language Models, building co-pilots and Retrieval-Augmented Generation (RAG) systems.
Coming with a strong research background, I bring a blend of academic rigor and industry experience to the forefront of generative AI and accelerated computing. During my PhD, I was developing deep learning methods to enhance seismic imaging.

Multi-task learning for low-frequency extrapolation and elastic model building from seismic data
Acquiring low-frequency data is challenging in practice for active seismic surveys. We propose to jointly reconstruct low-frequency data and a smooth background subsurface model within a multi-task deep learning framework. IEEE Transactions on Geoscience and Remote Sensing, 2022
-
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. Frontiers of Artificial Intelligence, 2022

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
