Specification synthesis is the process of deriving a model from the input-output traces of a system . Hybrid automata are intuitive,precise, tool independent, and at a high level of abstraction . Similarity detection in non-linearbehaviors is the main challenge for extracting such models . We address thisproblem by utilizing the Dynamic Time Warping technique . Our approach is passive, meaning that it does not need interaction with the system duringautomata synthesis from the logged traces; and online, which means that each input/output trace is used only once in the procedure . We evaluatedour algorithm in two industrial and simulated case studies . The accuracy of thederived automata show promising results. The accuracy in the derived automata have shown promising results, according to the authors. We evaluated our algorithm in the algorithm in
