A novel Fourier neural operator framework for classification of multi-sized images: Application to three dimensional digital porous media

1 code implementation18 Feb 2024 Ali Kashefi, Tapan Mukerji

First, we show that this approach is only effective for porous media with fixed sizes, whereas it fails for porous media of varying sizes.

Prediction of Effective Elastic Moduli of Rocks using Graph Neural Networks

1 code implementation30 Oct 2023 Jaehong Chung, Rasool Ahmad, WaiChing Sun, Wei Cai, Tapan Mukerji

This study presents a Graph Neural Networks (GNNs)-based approach for predicting the effective elastic moduli of rocks from their digital CT-scan images.

Physics-informed PointNet: On how many irregular geometries can it solve an inverse problem simultaneously? Application to linear elasticity

1 code implementation22 Mar 2023 Ali Kashefi, Leonidas J. Guibas, Tapan Mukerji

In this article, we demonstrate that PIPN predicts the solution of desired partial differential equations over a few hundred domains simultaneously, while it only uses sparse labeled data.

ChatGPT for Programming Numerical Methods

1 code implementation21 Mar 2023 Ali Kashefi, Tapan Mukerji

Specifically, we examine the capability of GhatGPT for generating codes for numerical algorithms in different programming languages, for debugging and improving written codes by users, for completing missed parts of numerical codes, rewriting available codes in other programming languages, and for parallelizing serial codes.

Direct Estimation of Porosity from Seismic Data using Rock and Wave Physics Informed Neural Networks (RW-PINN)

no code implementations30 Sep 2022 Divakar Vashisth, Tapan Mukerji

We present a rock and wave physics informed neural network (RW-PINN) model that can estimate porosity directly from seismic image traces with no or limited number of wells, with predictions that are consistent with rock physics and geologic knowledge of deposition.

Seismic Bayesian evidential learning: Estimation and uncertainty quantification of sub-resolution reservoir properties

no code implementations14 May 2019 Anshuman Pradhan, Tapan Mukerji

We present a framework that enables estimation of low-dimensional sub-resolution reservoir properties directly from seismic data, without requiring the solution of a high dimensional seismic inverse problem.
