In this paper, we consider the model class of hybrid automata whose dynamics are defined by affine differential equations. Given a set of time-series data, we present an algorithmic approach to synthesize a hybrid automaton exhibiting behavior that is close to the data, up to a specified precision, and changes in synchrony with the data. A fundamental problem in our synthesis algorithm is to check membership of a time series in a hybrid automaton. Our solution integrates reachability and optimization techniques for affine dynamical systems to obtain both a sufficient and a necessary condition for membership, combined in a refinement framework. The algorithm processes one time series at a time and hence can be interrupted, provide an intermediate result, and be resumed. We report experimental results demonstrating the applicability of our synthesis approach."}],"day":"01","arxiv":1,"doi":"10.1145/3447928.3456704","external_id":{"isi":["000932821700028"],"arxiv":["2102.12734"]},"isi":1,"year":"2021","citation":{"ista":"Garcia Soto M, Henzinger TA, Schilling C. 2021.
