Generative Digital Twins: A Novel Approach in the IoT Edge-Cloud Continuum
This paper introduces the concept of Generative Digital Twins (GDTs), an evolution of Digital Twins (DTs) that incorporates Generative AI to enhance prediction, control, optimization, and simulation capabilities. Originating in the manufacturing sector, DTs have been revitalized by advancements in IoT and AI, allowing them to interact with real-world data and achieve their goals more effectively. The paper defines GDTs, explores how Generative AI bridges model- and data-driven approaches, and highlights its benefits in IoT environments, particularly within Smart City scenarios where predictive accuracy, system robustness, and explainability are crucial.
Opportunistic Digital Twin: an Edge Intelligence enabler for Smart City
The paper discusses the importance of Digital Twins (DTs) enhanced by AI, Edge Computing, and IoT. It introduces the concept of “opportunistic” interpretation of DTs, creating dynamic digital replicas of physical objects through AI at the network edge. This approach is demonstrated through a traffic prediction use case, highlighting improved performance and resource efficiency.
Lingua Franca (LF) is a polyglot coordination language designed to enhance mainstream programming languages (currently C, C++, Python, TypeScript, and Rust) with deterministic reactive concurrency and timed behavior capabilities. Supported by a robust runtime system, LF enables concurrent and distributed execution of reactive programs deployable on the Cloud, the Edge, and even bare-metal embedded platforms.
