A Multi-Scale Deep Learning Framework for Projecting Weather Extremes

no code implementations21 Oct 2022 Antoine Blanchard, Nishant Parashar, Boyko Dodov, Christian Lessig, Themistoklis Sapsis

Weather extremes are a major societal and economic hazard, claiming thousands of lives and causing billions of dollars in damage every year.

Output-Weighted Sampling for Multi-Armed Bandits with Extreme Payoffs

1 code implementation19 Feb 2021 Yibo Yang, Antoine Blanchard, Themistoklis Sapsis, Paris Perdikaris

We present a new type of acquisition functions for online decision making in multi-armed and contextual bandit problems with extreme payoffs.

Informative Path Planning for Extreme Anomaly Detection in Environment Exploration and Monitoring

1 code implementation20 May 2020 Antoine Blanchard, Themistoklis Sapsis

An unmanned autonomous vehicle (UAV) is sent on a mission to explore and reconstruct an unknown environment from a series of measurements collected by Bayesian optimization.

Bayesian Optimization with Output-Weighted Optimal Sampling

1 code implementation22 Apr 2020 Antoine Blanchard, Themistoklis Sapsis

In Bayesian optimization, accounting for the importance of the output relative to the input is a crucial yet challenging exercise, as it can considerably improve the final result but often involves inaccurate and cumbersome entropy estimations.

Learning the Tangent Space of Dynamical Instabilities from Data

1 code implementation24 Jul 2019 Antoine Blanchard, Themistoklis P. Sapsis

For a large class of dynamical systems, the optimally time-dependent (OTD) modes, a set of deformable orthonormal tangent vectors that track directions of instabilities along any trajectory, are known to depend "pointwise" on the state of the system on the attractor, and not on the history of the trajectory.
