An active learning approach for improving the performance of equilibrium based chemical simulations
Autor: Mary Savino, Céline Lévy-Leduc, Marc Leconte, Benoit Cochepin
In this paper, we propose a novel sequential data-driven method for dealing with equilibrium based chemical simulations, which can be seen as a specific machine learning approach called active learning. The underlying idea of our approach is to consi
