[AllUsers-ISR] Talk Luís Marques - May 27, 16:00 - ISR Amphitheater

[Rui Araujo]

Dear all,

We are pleased to announce a talk by Luís Marques on May 27 at 16:00, at the ISR 
Amphitheater.

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).
