 	 abstract = {Recent literature has developed methods for localizing a low-dimensional vector w from paired comparisons of the form ``w is closer to p than q,'' where p and q are selected from a fixed set of landmark points and w does not change overtime.  In this work, we consider a time-varying extension of this problem, in which w evolves according to some unknown dynamics model.  We consider the task of actively selecting informative paired comparisons between landmark points to jointly estimate the state trajectory and identify the true dynamics model from a finite set of candidate models. Leveraging information-theoretic insights, we propose selecting pairs that  simultaneously  maximize  information  gain  about  both the trajectory and dynamics model, and propose a Bayesian method for tracking and system identification.   We demonstrate  the  efficacy  of  our  approach  with  numerical  simulations, showing that our method is able to jointly estimate state dynamics and identify the correct dynamical model.}
