Deep Modeling of Non-Gaussian Aleatoric Uncertainty

RA-L 2025

Deep learning offers promising new ways to accurately model aleatoric uncertainty in robotic state estimation systems, particularly when the uncertainty distributions do not conform to traditional assumptions of being fixed and Gaussian. In this study, we formulate and evaluate three fundamental dee

Learning to Forecast Aleatoric and Epistemic Uncertainties over Long Horizon Trajectories

ICRA 2023poster

Giving autonomous agents the ability to forecast their own outcomes and uncertainty will allow them to communicate their competencies and be used more safely. We accomplish this by using a learned world model of the agent system to forecast full agent trajectories over long time horizons. Real world…

Competency Assessment for Autonomous Agents using Deep Generative Models

IROS 2022poster

For autonomous agents to act as trustworthy partners to human users, they must be able to reliably communicate their competency for the tasks they are asked to perform. Towards this objective, we develop probabilistic world models based on deep generative modelling that allow for the simulation of a…
