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, […]
