Transfer learning for predicting source terms of principal component transport in chemically reactive flow

no code implementations1 Dec 2023 Ki Sung Jung, Tarek Echekki, Jacqueline H. Chen, Mohammad Khalil

The performance of the reduced-order model with a sparse dataset is found to be remarkably enhanced if the training of the ANN model is restricted by a regularization term that controls the degree of knowledge transfer from source to target tasks.

Generalized Joint Probability Density Function Formulation inTurbulent Combustion using DeepONet

no code implementations5 Apr 2021 Rishikesh Ranade, Kevin Gitushi, Tarek Echekki

The DeepONet is a machine learning model that is parameterized on the unconditional means of PCs at a given spatial location and discrete PC coordinates and predicts the joint probability density value for the corresponding PC coordinate.

An Efficient Machine-Learning Approach for PDF Tabulation in Turbulent Combustion Closure

no code implementations18 May 2020 Rishikesh Ranade, Genong Li, Shaoping Li, Tarek Echekki

In this work, we address these issues by introducing an adaptive training algorithm that relies on multi-layer perception (MLP) neural networks for regression and self-organizing maps (SOMs) for clustering data to tabulate using different networks.
