Active Learning-Based Input Design for Angle-Only Initial Relative Orbit Determination
Kui Xie, Giovanni Romagnoli, Giordana Bucchioni +1
Accurate relative orbit determination is a significant challenge in modern space operations, particularly when relying only on angular measurements. The inherent observability limi…

Online design of experiments by active learning for nonlinear system identification
Kui Xie, Alberto Bemporad
We investigate the use of active-learning (AL) strategies to generate the input excitation signal at runtime for system identification of linear and nonlinear autoregressive and st…
