Title: Covert Data Communications in Cell-Free Internet-of-Things Networks
Abstract: Cell-free wireless communications is a new paradigm within the future 6G networks towards implementation of the Internet of intelligence with connected people and things. In a cell-free network, a large number of distributed access points are connected to a central processing unit and serve a smaller number of users over the same time-frequency resources. The system has shown great potential in improving network performance in some perspectives compared to the co-located and conventional small-cell systems. The next-generation Internet-of-Things systems could be dispersed over large areas under a cell-free network setting. This has given rise to security concerns stemming from the exposure of wireless channels and the exponential growth of connected devices. In this talk, a novel covert downlink transmission scheme is presented that jointly optimizes beamforming and artificial noise vectors to obscure critical transmissions at an eavesdropper in CF IoT Networks.

Title: Generative AI for rapid and scalable behaviour modelling in cities
Abstract: Understanding human behaviours is critical to improving operation efficiency, individual and organisational productivity, public health management, and quality of life in cities. The proliferation of sensors and Internet of Things leads to new opportunities and challenges for human behaviour modelling and forecasting behavioural patterns at scale. Annotating behaviours of interest is expensive and often infeasible. This demands new ways for modelling behaviours at scale, moving away from fully-supervised learning approaches. Recent Generative AI approaches and Large Language Models has become a compelling choice for modelling mobility behaviours, especially in cases when training data is limited. I will present our self-supervised learning (SSL) approaches for multimodal sensor data, with different applications as examples, including human behaviour recognition and traffic flow forecasting. I will also talk about how we handle data heterogeneity and fusion of heterogenous time-series towards robust representation. I will also present a new versatile paradigm, leveraging Large Language Models (LLMs) for time-series forecasting, including for mobility and energy domain, using natural language prompts.

Title: The implementation of machine learning enhanced next-generation optical access networks— rationale, challenges and emerging solutions
Abstract: Optical access networks are envisioned to become increasingly complex as they support more and more diverse and immersive services, each with a different capacity, latency, and reliability need. While machine learning has been touted as a silver bullet that will intelligently manage network operations and resources to meet these demands, as it had been anticipated for core and metro networks, there exist various challenges that need to be addressed to progress machine learning models from research to production. We first aim motivate the continued push to advance optical access networks and rationalize the use of machine learning in these networks. We then highlight the challenges that are especially amplified due to the traffic dynamicity and heterogeneity, data scarcity, and computation-resource constraints of optical access networks. We discuss emerging machine learning approaches that are being explored to address these challenges. Finally, we consider an example of an online reinforcement learning based bandwidth allocation scheme to address concept drift in machine learning enhanced optical access network.
