Title: The Bottlenecks in Advancing Foundation Models for Internet of Things (IoT) Applications
Speaker: Prof. Tarek Abdelzaher
Abstract: Advances in self-supervised AI revolutionized modern machine intelligence, but important challenges remain when applying these solutions in IoT contexts – specifically, on lower-end distributed embedded devices with multimodal specialized sensors, where ample training data are not readily available. The talk discusses the bottlenecks in advancing self-supervised machine intelligence services and foundation models for Internet of Things (IoT) applications. We argue that, at training time, the key bottlenecks are data-related. Embedded computing relies on scarce sensor data modalities, unlike those commonly addressed in mainstream AI, necessitating solutions for efficient learning from scarce sensor data. At inference time, the bottlenecks are computational, calling for improved resource economy and novel scheduling policies. Further ahead, the convergence of AI around large language models (LLMs) introduces additional model-related challenges in embedded contexts. The paper discusses novel research directions in addressing these bottlenecks, covering data-, resource-, and model-related challenges in the IoT domain.

Title: 6G NTN Communication and Edge Computing for Satellite IoT
Speaker: Prof. Symeon Chatzinotas
Abstract: NTN is regarded as one of the most important milestones in the 6G era, aiming at providing ubiquitous network coverage. Such coverage will largely benefit IoT applications, which often have to operate in remote areas, far from the centers of huma activity e.g. environmental monitoring, energy grid plants and transport networks. In this talk, we will dive into advance communication and edge computing capabilities that are envisaged to support such satellite IoT dervices. Starting from connectivity, we will investigate the state of the art in NTN direct to X, highlighting current capabilities and open challenges in RAN and architecture layers. Subsequently, we focus on space edge computing with a particular emphasis on neuromorphic AI and semantic communications.
