DATA DRIVEN WIRELESS COMMUNICATIONS AND SENSING
Abstract: In recent years, we have witnessed rapid growth in data generation and transmission due to the emergence of mobile, computation, and sensory devices. Advancements in machine learning are enabling techniques to exploit these data to both improve the existing systems, and design new innovative systems (with CHATGPT a notorious example). An interesting question is how this trend will impact future wireless communications and sensing systems, and even what we will teach about how to design these systems. In this talk, we will discuss how AI will future wireless systems, and how classical model driven design and analysis will be replaced by data-driven design and analysis. In particular, I will discuss the need for challenge datasets and my group’s effort in this direction.

Democratizng Innovation For Next Generation Cyber Infrastructure
Abstract: Recently, information communications have been increasingly utilized as a social infrastructure for continuity of socio-economic activities and maintaining human life. Also, cyber physical systems are increasingly playing an important role in our society. Thus, we are currently devoting ourselves to developing next generation cyber infrastructure which is a foundation to support our cyber physical systems for 2030s, including telecommunication extended to space and ocean, computation, sensing, artificial intelligence, security, ethics and data governance. In such efforts for defining, developing and deploying next generation cyber infrastructure, we posit that it is significant to take a democratic approach for accelerating innovations, that is, bringing all the stakeholders in the eco-system, especially providing flexible customization to the infrastructure so that general people that can clearly define the social problems may be able to develop innovative solutions and to evaluate the social acceptance of such solutions.To this end, we have been working on softwarization, virtualization and modularization of telecommunication infrastructure components through open interfaces and democratizing the development of cyber infrastructure by privatization such as Private5G/Local 5G. In this presentation, we will introduce overall R&D landscape for next generation cyber infrastructure in Japan as well as specific research activities that our research lab are pursuing, especially focusing on democratization approach.

Neural Feature Learning For Engineering Problems
Abstract: Using deep neural networks as elements of engineering solutions can potentially enhance the overall performance of the system. However, most existing practices that use DNNs as black boxes make integrating DNN modules in engineering systems hard. In this paper, we address one of such difficulties: in engineering solutions, we often look for parameterized solutions that perform well in a collection of scenarios. In most problems, this means the DNN modules are trained and used in different environments. Instead of using a transfer learning or multi-task learning formulation, which are common in the literature, we argue that such problems are intrinsically about the multi-variate dependence between the data, the label, and the environment parameters. Using an example of symbol detection over wireless fading channels with interference, we demonstrate that such problems can generally be solved as a modal decomposition. We develop new metrics to measure the information contents of features and some basic neural network architectures to perform geometric operations in the space of feature functions. With these building blocks, we discuss the steps to build a receiver that does not require any online training but can adapt to different fading scenarios when given the channel state information(CSI). We use the symbol detection problem as an example to discuss some key issues and steps to include DNN modules in complex engineering systems.

Security In Internet Of Things (IoT)
Abstract: Internet of Things (IoT) are gaining popularity and will be increasing ubiquitous in near future. They will find use in a vast array of applications ranging from sensing, actuating, monitoring, and decision-making efforts. The expansive usage, while facilitating broad range of applications will bring in challenges related to security. The resource limitations of IoT will complexities to these challenges. In this talk, we will overview these challenges and discuss potential solutions that have in developed in our research efforts. We will discuss about continual authentication approaches to ensure security in sensing elements of IoT system. Detection of threats or malicious behavior and protection of some obvious threats will be the topic of the next issue that we will explore. In addition, we will discuss about the vulnerabilities that can be exploited for various attack scenarios in IoTs. The talk will be concluded with a few remarks regarding the future research directions on IoT security.
