Title: Key Communication and AI/Machine Learning Technologies for Intelligent Wireless Networks
Abstract:
Driven by the explosively increasing intelligent applications such as intelligent transportation, future wireless networks, particularly 6G, must embrace intelligence and require the cooperation of communication and artificial intelligence/machine learning (AI/ML) technologies. These technologies include non-orthogonal multiple access (NOMA), mobile edge computing (MEC) and reconfigurable intelligent surface (RIS), deep reinforcement learning, federated learning, etc. In this talk, I shall 1) introduce energy-efficient design NOMA enabled RIS systems; 2) present machine learning algorithms for intelligent wireless communications; 3) discuss future possible research topics on intelligent wireless communications.

Title: Asynchronous and User-centric Reinforcement Learning for the Metaverse
Abstract:
The Metaverse has brought about a revolution in the internet space and is an important element of Web 3.0. The introduction of the Metaverse opened doors to not only interactive socialization through Extended Reality (XR), but also through its highly connected virtual world and ecosystem. With the extensive research and development in XR technologies, the once-so-expensive equipment has become affordable for both professionals and the common man. The increasing accessibility of XR equipment drives the penetration of XR technologies, and it is postulated to be a key feature in multi-player games, workplace meetings, and, potentially, simulations for scientific research and engineering. As the mobility of XR devices is attached with great importance, we need to consider XR technologies in the context of wireless communications. In this talk, I will introduce two intriguing scenarios (i) Real-time 3D reconstruction over asynchronous multi-stage wireless communication, and (ii) Virtual Reality (VR) over User-centric server-aided computing.

Title: A Game Theoretic Approach for Intelligent Transportation Systems
Abstract:
The exponential growth in citizens and transportation sources raises many challenges, such as massive traffic jams and accidents. The existing Internet-of-Things (IoT)-based transport management schemes are costly (money and time) and unable to avoid congestion in real-time. In this talk, the speaker discusses proposed smart traffic management (STM) framework by combining the concept of Internet-of-Vehicles (IoV) and game theory for efficient traffic load management on an uncontrolled road’s intersection. The road intersection is a non-cooperative game, where Nash Equilibrium (NE) sets traffic for each route so that no individual can improve its performance by changing its strategy. In a highly congested traffic scenario, the vast number of players/vehicles significantly affects the strategy selection process. The speaker introduces an agent representative approach to overcome this issue, where spectral clustering combines players with the same strategies and payoff in a collaborative group. The talk includes some experimental results which show that the proposed traffic game significantly outperforms the existing schemes in terms of traffic intensity rate, average stopped cars, average waiting time at an intersection, average travel time, and average speed.

Title: Spatial and Frequency Domain Color Interpolation for CFA
Abstract:
This seminar addresses the problem of interpolating missing color components at the output of a Bayer color filter array (CFA), a process known as demosaicking. A luma-chroma demultiplexing algorithm is presented in detail, using a least-squares design methodology for the required bandpass filters. A systematic study of objective demosaicking performance and system complexity is carried out, and several system configurations are recommended. The method is compared with other benchmark algorithms in terms of CPSNR and S-CIELAB ΔE * objective quality measures and demosaicking speed. Finally, some deep learning-based image processing applications are introduced.
