The forty-seventh UQSay seminar on UQ, DACE and related topics will take place online on Thursday afternoon, May 19, 2022. 2–3 PM — Mélanie Rochoux (CECI, Cerfacs, CNRS) — [slides] Assimilating fire front position and emulating boundary-layer flow simulations for wildland fire behavior ensemble prediction and reanalysis Monitoring wildfire behavior has recently emerged as a […]
14h00-15h00 – Salle du conseil (L2S) Uncertainty-aware control strategies for safe learning-based robotic autonomy Thomas Lew (Stanford University, USA) Abstract. The deployment of autonomous robotic systems in partially unknown environments requires agents that explicitly reason about uncertainty, adapt to their environment, and guarantee safe operation. For example, a robot assisting astronauts in space should be […]
Speaker — David Hong (Department of Statistics and Data Science, University of Pennsylvania, Philadelphia, PA, US) Abstract — Principal component analysis (PCA) is a workhorse method for identifying low-dimensional (i.e., low-rank) structure in noisy data and is ubiquitous in signal processing. However, it estimates the underlying low-rank structure sub-optimally when the samples have heterogeneous quality, […]
The forty-sixth UQSay seminar on UQ, DACE and related topics will take place online on Thursday afternoon, April 21, 2022. 2–3 PM — Antoine Ajenjo (EDF R&D, FEMTO-ST) — [slides] Robustness assessment of reliability-oriented quantities of interest for the safety of industrial structures using the info-gap framework Structural reliability is of particular interest for risk-sensitive […]
