Probabilistic characterization of the effect of transient stochastic loads on the fatigue-crack nucleation time
Stephen Guth, Themistoklis P. Sapsis
The rainflow counting algorithm for material fatigue is both simple to implement and extraordinarily successful for predicting material failure times. However, it neglects memory e…
Output-Weighted Optimal Sampling for Bayesian Experimental Design and Uncertainty Quantification
Antoine Blanchard, Themistoklis Sapsis
We introduce a class of acquisition functions for sample selection that leads to faster convergence in applications related to Bayesian experimental design and uncertainty quantifi…
Sparse Methods for Automatic Relevance Determination
Samuel H. Rudy, Themistoklis P. Sapsis
This work considers methods for imposing sparsity in Bayesian regression with applications in nonlinear system identification. We first review automatic relevance determination (AR…
A Local Spectral Exterior Calculus for the Sphere and Application to the Shallow Water Equations
Clauson Carvalho da Silva, Christian Lessig, Boyko Dodov +2
We introduce , a local spectral exterior calculus for the two-sphere . provides a discretization of Cartan's exterior calculus on formed by…
Informative Path Planning for Extreme Anomaly Detection in Environment Exploration and Monitoring
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. The su…
Bayesian Optimization with Output-Weighted Optimal Sampling
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 b…
