SKEL | The AI Lab organised an invited talk hosting Prof. John S. Baras, a Distinguished University Professor, holding the Lockheed Martin Chair in Systems Engineering, in the Institute for Systems Research (ISR) and the ECE Department at the University of Maryland College Park (UMD), to deliver a talk titled AI Impact on Systems Engineering and Systems Engineering Impact on AI on Friday 19 January 2024, at 12.00pm (Athens time).
The talk took place physically at the Lecture Room of the Institute of Informatics & Telecommunications, while participation was also possible via zoom.

About the talk: The complexity of systems has increased dramatically. As a result, it is not feasible to construct accurate models for many system components. We now have large datasets and advances in ML and AI that can be used in Systems Science and Engineering problems. We propose an Integrated Data-Driven (ML and AI) and Model-Based Systems Engineering (IDDMBSE) framework for the design of autonomous robotic systems. Such designs for specific use cases require careful co-design of both the hardware and the software elements with multiple domain-specialist team working on different aspects of the system often without the knowledge of concurrent changes being implemented by a different team. Developing such complex systems can significantly benefit from a formalized process that can provide a unified framework for the design of the system. The Model- Based Systems Engineering (MBSE) framework was introduced precisely to tackle this problem through the use of Systems Modeling Language (SysML) as the unifying tool for modeling and managing requirements, structure, and behavior of the system and guiding the overall design process through design optimization and verification using co-simulation.
In our past work, we demonstrated the application of the MBSE framework for robot grasping. However, the need for autonomy in robotic systems has resulted in the incorporation of data-driven algorithms and techniques in the autonomy stack that cannot be fully captured in the conventional MBSE framework. Our framework addresses this challenge of designing systems by integrating model-based and data-driven techniques. Our IDDMBSE framework is general and can be applied to many other autonomous systems. In the opposite direction AI systems consist of hardware and software components with special properties. We propose a framework for using Systems Engineering methodology to design high performance AI systems by viewing the problem as a SE problem for hardware-software co-design, albeit with novel requirements.
Speaker Bio: John S. Baras is a Distinguished University Professor, holding the Lockheed Martin Chair in Systems Engineering, in the Institute for Systems Research (ISR) and the ECE Department at the University of Maryland College Park (UMD).
