From Age of Information to Semantic Communications

Anthony Ephremidis, Professor in Electrical Engineering University of Maryland

Abstract

After a short review of the concept of Information Freshness (a.k.a. Age of Information) where its role as a metric and a tool is developed, it will be shown how it leads naturally to other information properties that can be called Semantic. The term “Semantic” needs clarification and represents a paradigm shift in communications from the traditional one that has been based on Shannon’s Theory. Semantic properties are meaningful and useful in a variety of applications. They also provide a potential link between Information Theory and Signal Processing. Finally, the concept of freshness is linked to the current focus on data driven methodologies that emerge from the transition to Artificial Intelligence and Machine Learning.

Biography

Anthony Ephremides (etony@umd.edu) received his B.S. degree from the National Technical University of Athens (1967), and M.S. (1969) and Ph.D. (1971) degrees from Princeton University, all in Electrical Engineering. He has been at the University of Maryland since 1971, and held a joint appointment as Professor in the Electrical Engineering Department and a founding member of the Institute of Systems Research (ISR). He was also a co-founder of the NASA Center for Commercial Development of Space on Hybrid and Satellite Communications Networks established in 1991 at Maryland as an off-shoot of the ISR. He served as Co-Director of that Center from 1991 to 1994. He also held the endowed Cynthia Kim Eminent Chair of Information Technology and in 2012 he has been designated as Distinguished University Professor at the University of Maryland. Since 2021 he has become Professor Emeritus.

His interests are in the areas of communication theory, communication systems and networks, queuing systems, signal processing, and satellite communications, cross-layer design, and has initiated research in the field of Ad Hoc wireless networks.  Most recently he has spearheaded the area of semantic communications, including the Age of Information.

He has been the President of the Information Theory Society of the IEEE (1987) and has served on its Board of Governors almost continuously from 1981 until recently.  He was elected to the Board of Directors of the IEEE in 1989 and 1990. He won the IEEE Donald E. Fink Prize Paper Award (1992) and he was the first recipient of the Sigmobile Award of the ACM (Association of Computer Machinery) for contributions to wireless communications in 1997. He has been an IEEE Life Fellow. He has served on the Editorial Boards of the IEEE Transactions on Automatic Control, IEEE Transactions on Information theory, the Journal of Wireless Networks, and the International Journal of Satellite Communications. He has been the Editor-in-Chief of the Journal of Communications and Networks since 2016.

The View from Industry

Jonas Bjurel, Senior principal engineer and Chief architect Ericsson cloud infra-structure.

Johan Åkesson, Associate Director of Computational Engineering at Carrier

Biography Jonas Bjurel

Jonas has 35+ year’s experience with communication technologies- and architectures in various contexts. 

Many years ago, Jonas lead the architecture development for the WCDMA application infra-structure, since then Jonas has been continuously engaged in pushing the evolution of the communication industry’s technologies-, architectures-, and capabilities including roles and tasks such:

– At the Millenium, Jonas Co-founded a joint venture between Ericsson and Juniper Networks, where he served

  as CTO, as well as Vice President of product management and engineering, leading the development of the

  first ever high performance router-based Mobile packet Gateway (GGSN).

– In 2003, Jonas lead the architecture definition- and development of Ericsson’s first all Ethernet based communication infrastructure, base for all of Ericsson’s core network applications. This platform shared many of the properties that you would see in today’s private cloud solutions.

– In 2009, Jonas co-founded “Ericsson In-game communication”, a wireless communication platform for the on-line gaming industry, the platform was launched at the Mobile World Congress 2010, and later came to be part of several on-line gaming platforms before it was spun out from Ericsson. 

Since 2013, Jonas have had several leading roles in Ericsson’s journey towards an all cloud native paradigm, including both the infra-structure and the applications, as well as Ericsson’s engagement in Open-source in this area.

Jonas today holds the position as Chief architect for the “Ericsson cloud infrastructure”, in this position he oversees the architecture and the technology strategies for Ericsson’s virtualization- and container platforms.  

Jonas will talk around the following topics:

– The cloud journey: How it all came together, where we are now, and where it might lead us

– The importance of automation: Everything everywhere needs automation-, needs to handled as code (x-OPS), and needs to be declarative.

– How will the networks provide differentiated network experience, and will network programability provide such experience.

– How could the IT-, OT-, and Communication industries become better aligned around technologies, standards- and best practices.

Algebraic Control for Automating Program Analysis

Laura Kovacs, Professor in Computer Science, Technical University of Wien

Abstract

We describe applications of symbolic computation towards automating the formal analysis of while-programs implementing polynomial arithmetic.

We combine methods from static analysis, computer algebra and probability theory in order to automatically derive loop invariants and capture how the value distributions of loop variables influence the functional behavior of loops. Our results yield computer-aided solutions in support of formal software verification, compiler optimization, and probabilistic programming. We demonstrate the practical use of our techniques via illustrative example and using our Polar static analyzer. 

Biography

Laura Kovacs is a full professor of computer science at the TU Wien, leading the automated program reasoning (APRe) group of the Formal Methods in Systems Engineering division. Her research focuses on the design and development of new theories, technologies, and tools for program analysis, with a particular focus on automated assertion generation, symbolic summation, computer algebra, and automated theorem proving. She is the co-developer of the Vampire theorem prover and a Wallenberg Academy Fellow of Sweden. Her research has also been awarded with a ERC Starting Grant 2014, an ERC Proof of Concept Grant 2018, an ERC Consolidator Grant 2020, and an Amazon Research Award 2020. Recently, she received financial support from LEA Frauenfonds to disseminate unplugged computer science to elementary schools, while organising computer science workshops with school children at the TU Wien.
