On November 8, we organized a scientific seminar on “How Much Energy Is Too Much? On Challenges and Promises of Subspace Identification for Safety“. The scientific seminar was led by Marek Wadinger, a PhD student at STUBA. The scientific seminar was organized in the framework of the FrontSeat project as part of the seminar series on “Research Seminar on Smart Cybernetics”.
Abstract:
This talk examines the challenges and promises of energy-based change-point detection (CPD) for safety in industrial systems, where dynamic conditions—such as aging, seasonal shifts, and control inputs—demand adaptable and precise monitoring methods. Conventional CPD approaches often fall short in these non-stationary environments, struggling with limited adaptability and delayed response to critical changes. Our proposed method, leveraging online Dynamic Mode Decomposition with control (ODMDwC), provides a dynamic alignment with evolving data patterns by incorporating control effects and higher-order time-delay embeddings. This approach quantifies dissimilarity between observed data and model behavior as “energy,” establishing a framework for identifying shifts in complex system dynamics. Yet a critical question remains: How much energy is too much?—or, how to set an actionable threshold for this dissimilarity to ensure safety and effective application in high-stakes environments.
This project has received funding from the European Union’s Horizon under grant no. 101079342 (Fostering Opportunities Towards Slovak Excellence in Advanced Control for Smart Industries).
