qPOTS: Efficient batch multiobjective Bayesian optimization via Pareto optimal Thompson sampling

no code implementations24 Oct 2023 S. Ashwin Renganathan

Classical evolutionary approaches for multiobjective optimization are quite effective but incur a lot of queries to the objectives; this can be prohibitive when objectives are expensive oracles.

Data-Driven Wind Turbine Wake Modeling via Probabilistic Machine Learning

no code implementations6 Sep 2021 S. Ashwin Renganathan, Romit Maulik, Stefano Letizia, Giacomo Valerio Iungo

Physics-based models that capture the wake flow-field with high-fidelity are computationally very expensive to perform layout optimization of wind farms, and, thus, data-driven reduced order models can represent an efficient alternative for simulating wind farms.

Enhanced data efficiency using deep neural networks and Gaussian processes for aerodynamic design optimization

no code implementations15 Aug 2020 S. Ashwin Renganathan, Romit Maulik and, Jai Ahuja

Furthermore, we show that multiple optimization problems can be solved with the same machine learning model with high accuracy, to amortize the offline costs associated with constructing our models.

Aerodynamic Data Fusion Towards the Digital Twin Paradigm

no code implementations2 Nov 2019 S. Ashwin Renganathan, Kohei Harada, Dimitri N. Mavris

For example, two sources of pressure fields about an aircraft are fused based on measured forces and moments from a wind-tunnel experiment.
