  • Everywhere Reconfigurable Intelligent Surfaces: The New Bandwagon Problem in Wireless Communications

    In the 80s when you asked people what type of research they are conducting mostly the answer was “High Speed Networks”. Later it was “the ATM Networks”; then “Sensor Networks”, “Cognitive Radio Networks”, “all types of MIMOs”, etc.etc. The list is long. Many researchers were blindly jumping on the bandwagon and writing many many papers on those subjects without worrying about the actual contributions. It was like a paper writing race and this trend is still continuing with the not-so-new concept of “Reconfigurable Intelligent Surfaces”. It looks like many researchers just open their eyes and find the topic interesting and start to write papers after papers of which some of them make no sense or have no actual contributions. They create some artificial scenarios and develop some mathematical models to participate into the paper writing race. Many of them do not even care about the actual functionalities of the RIS. The objective should be to advance the technology and demonstrate the utilization of this concept and not just keep writing useless papers. This can be called the “Academic Pollution”. My personal interest in this topic was based on how to solve the distance problem of the TeraHertz band communications back in 2011. We had proposed solutions like distance adaptive modulation, multipath effects and Ultra Massive MIMO (UM MIMO) in order to combat the distance problem in THz wireless systems. Finally forming a consortium with European universities back in 2014, this RIS research (http://www.visorsurf.eu) started officially by obtaining funding from the very challenging (3% acceptance rate) from EU FET (Future Emerging Technologies) program in 2016. The team consisting of almost 40 researchers with different backgrounds, Materials, Physics, Computer Science, Electrical Engineering, Communications/Networking, Antenna, Software, Hardware, Chip Design and Fabrication worked harmoniously together and produced impactful results the last 6 years. Not only papers were published but also patents were obtained. In this talk, the basic ideas behind Visorsurf will be introduced. The details of the surface operations are explained. Many realistic future challenges for the next decade will be presented.

  • Evolutionary Surrogate-assisted Prescription in the COVID-19 Pandemic and Beyond

    How can we make good decisions in healthcare, business, engineering, education, and indeed in life in general? Good decisions are often based on experience: recalling what decisions were made in similar situations in the past, how well they worked out, and modifying them to achieve good outcomes in current situation. Evolutionary Surrogate-assisted Prescription (ESP) is a machine learning technology that makes it possible to come up with good decision strategies automatically. The idea is to use historical data to build a predictive surrogate model, and population based search (i.e. evolutionary computation) to discover good decision strategies against it. I’ll review the technology and evaluate it in several examples, including optimizing behavior in sequential decision tasks, and optimizing non-pharmaceutical interventions in the COVID-19 pandemic. The method is found to be sample efficient and creative, forming a foundation for optimizing many decision tasks in the future.

  • Wireless Federated Learning for 6G Networks

    Conventional machine learning techniques are conducted in a centralized manner. Recently, the massive volume of generated wireless data, the privacy concerns and the increasing computing capabilities of wireless end-devices have led to the emergence of a promising decentralized solution, termed as Wireless Federated Learning (WFL). In this talk, the application of WFL in 6G networks will be presented. After analyzing the key concepts of WFL, we will discuss the core challenges of WFL imposed by the wireless environment. Finally, we shed light to the future directions of WFL, aiming to compose a constructive integration of FL into the future wireless networks. Finally, a novel communication protocol for WFL networks, that is based on NOMA will be introduced and optimized.
