Abstract: In order to test an autonomous behavior controller for a technical system, the following are input: a machine model for physically simulating the technical system; an environment model modelling an environment of the technical system; as well as a disruption model modelling potential disruptions in the environment. Disruption data is generated by means of the disruption model, and the environment model is modified according to the disruption data. Environment-specifically simulated sensor data the technical system is then generated by means of the modified environment model and the machine model. According to the simulated sensor data, control data is generated for the technical system by the autonomous behavior controller. An operating behavior of the technical system induced by the control data is then simulated by means of the machine model. Furthermore, a performance value quantifying the operating behavior is determined and output as a test result.

Abstract: A device obtains a set of time series data monitored on a machine and further obtains first label information indicating a first time window in the time series data. The device determines a first probabilistic model, describing dynamics of the time series data inside the first time window, and a second probabilistic model describing dynamics of the time series data adjacent to the first time window. Based on the first and second probabilistic models, the device determines a first part of the time series data that is estimated to match the first probabilistic model and a second part of the time series data that is estimated to match the second probabilistic model, e.g., using a hidden Markov model. The device then determines second label information indicating a second time window which includes the first part of the time series data and excludes the second part of the time series data.
