The majority of projects dealing with monitoring and diagnosis of Cyber Physical Systems (CPSs) relies on models created by human experts. But these models are rarely available, are hard to verify and to maintain and are often incomplete. Data-driven approaches are a promising alternative: They leverage on the large amount of data which is collected nowadays in CPSs, this data is then used to learn the necessary models automatically. For this, several challenges have to be tackled, such as real-time data acquisition and storage solutions, data analysis and machine learning algorithms, task specific human-machine-interfaces (HMI) and feedback/control mechanisms. In this paper, we propose a cognitive reference architecture which addresses these challenges. This reference architecture should both ease the reuse of algorithms and support scientific discussions by providing a comparison schema. Use cases from different industries are outlined and support the correctness of the architecture.
