Fourier Representations for Black-Box Optimization over Categorical Variables

no code implementations8 Feb 2022 Hamid Dadkhahi, Jesus Rios, Karthikeyan Shanmugam, Payel Das

In order to improve the performance and sample efficiency of such algorithms, we propose to use existing methods in conjunction with a surrogate model for the black-box evaluations over purely categorical variables.

Accelerating Physics-Based Simulations Using Neural Network Proxies: An Application in Oil Reservoir Modeling

no code implementations23 May 2019 Jiri Navratil, Alan King, Jesus Rios, Georgios Kollias, Ruben Torrado, Andres Codas

We develop a proxy model based on deep learning methods to accelerate the simulations of oil reservoirs--by three orders of magnitude--compared to industry-strength physics-based PDE solvers.
