Below you can find the title, abstract, and short bio of the speaker. We look forward to seeing you there! --- Title: Uncertainty Calibration for Safety-Critical Robotics using Conformal Prediction Abstract: Robot dynamics models, whether learned, simulated, or analytical, can be inaccurate in unseen environments. This creates a challenge for safe control: uncertainty estimates often become uncalibrated, which can lead to overconfident plans and unsafe executions. In this talk, I will present conformal prediction-based methods that calibrate approximate uncertainty estimates from inaccurate dynamics models and construct prediction sets guaranteed to contain future robot states at a user-specified rate. These methods provide non-asymptotic, model-agnostic guarantees and adapt to the robot’s state, action, and observations, making them informative for downstream safe planning. I demonstrate the approach on a double integrator system with random perturbations and significant model mismatch. Short bio: Luís Marques is a Ph.D. student in the Robotics Department at the University of Michigan, advised by Dmitry Berenson. His work lies at the intersection of uncertainty quantification, safe robotic decision-making, and conformal prediction, with a focus on calibrating dynamics uncertainty under both aleatory disturbances and model mismatch. Previously, Luís received a M.S. in Robotics from the University of Michigan (2025) and a M.Eng. in Aeronautical Engineering from Imperial College London (2023). --- Best regards, Rui Araújo <pre class="moz-signature" cols="82">-------------------------------------------------------------- Rui Alexandre de Matos Araujo ISR-Institute for Systems and Robotics DEEC-Department of Electrical and Computer Engineering University of Coimbra, Polo II PT-3030-290 Coimbra - Portugal Email: <a class="moz-txt-link-abbreviated" href="mailto:rui@isr.uc.pt">rui@isr.uc.pt</a> ; Tel: +351-239.796276/00 Web: <a class="moz-txt-link-freetext" href="https://home.deec.uc.pt/~rui/">https://home.deec.uc.pt/~rui/</a> ; <a class="moz-txt-link-freetext" href="http://ruiaraujo.rf.gd/">http://ruiaraujo.rf.gd/</a> -------------------------------------------------------------- </pre> </body> </html>
