Neural parameter calibration for large-scale multiagent models. [PDF]
Proc Natl Acad Sci U S A, 2023 Computational models have become a powerful tool in the quantitative sciences to understand the behavior of complex systems that evolve in time. However, they often contain a potentially large number of free parameters whose values cannot be obtained from theory but need to be inferred from data.

Simultaneous Parameter Calibration, Localization, and Mapping [PDF]
Advanced Robotics, 2012 The calibration parameters of a mobile robot play a substantial role in navigation tasks. Often these parameters are subject to variations that depend either on changes in the environment or on the load of the robot. In this paper, we propose an approach
