Abstract Photonic materials are the backbones of optical communication, sensing and imaging systems. The advent of artificial intelligence, internet of things and human-machine interfaces require optical information perception, data communication and storage with a much higher bandwidth, smaller footprint yet extremely low power consumption. Bulk materials can no longer support these tasks. Development of advanced […]

Abstract The next frontier of the Internet of Things (IoT) lies in transforming today’s smart devices into collaborative cognitive agents – an ecosystem termed the Internet of Intelligent Things (IoIT). While current IoT systems center on raw data exchange, they fall short of enabling true collaboration: devices cannot share meaningful insights or align their objectives […]

Online via Zoom link: https://hku.zoom.us/j/2025021302 Abstract With the commercialization of 5G technology, research on 6G has emerged as a key focus in the field of wireless communications. In this talk, we explore three candidate waveforms for 6G, designed to meet its stringent requirements for throughput, reliability, and integrated sensing and communications (ISAC). We begin by […]

Abstract Recently, the International Telecommunication Union (ITU) has identified integrated sensing and communication (ISAC) as a primary usage scenario for the sixth-generation (6G) cellular networks in IMT-2030 Framework. As a result, future cellular networks will provide not only communication services, but also sensing services such as localization and tracking. However, how to exploit the existing […]

Abstract Federated learning is a distributed artificial intelligence framework, which allows multiple edge devices to train a single model collaboratively. In this talk, we first introduce a personalized federated learning algorithm which can tackle the issues of data heterogeneity and device heterogeneity. Then, we present a content-based viewport prediction framework for 360-degree video streaming, wherein […]
