报告摘要：
With the maturity of edge computing and the large amount of data generated by loT devices, we have witnessed an increasing number of intelligent applications in wireless networks. The growing awareness of privacy further motivates the wide study and deployment of federated learning, a collaborative distributed model training framework for predictive tasks, However, a wide range of applications, more broadly relevant to data analytics and query in wireless networks, cannot be well supported by this framework. These applications usually require more complex and diverse aggregation methods, instead of the simple weight aggregations, and are broadly nourished by statistics, information theory, and signa processing, besides machine learning. This talk aims to present the recent advances in federated analytics at the intersection of data science, wireless communication, and security and privacy, We will present the definition, taxonomy, and architecture of the federated analytics techniques. It will also cover several practical and important data analytics tasks in wireless networks, including federated anomaly detection, federated frequent pattern analysis, federated distribution estimation and skewness analytics. Finally, we will present important challenges, open problems, and future directions at the intersection of federated learning/analysis and wireless networks.

报告摘要：
This speech explores the transformative potential of Generative Al (GAl) across various domains. Firstly, we examine the use of Large Language Models (LLMs)in repeated games to develop practical strategies aligning with the folk theorem's equilibrium conditions, enhancing cooperative behavior through future payoff considerations. Secondly, we address lowlight image enhancement in teleoperation using diffusion-based Al generated content (AlGC) models. A Vision Language Model (VLM)empowered contract theory framework optimizes AlGC task allocation and pricing under information asymmetry, improving resource management for teleoperators and edge servers. In the realm of autonomous driving, we integrate Federated Learning (FL)with Vision-language models (VLMs) in Graph Visual Question Answering (GVQA), highlighting advancements in privacy preservation, reduced communication costs, and maintained model performance. Lastly, an LLM-based semantic communication (SC) framework for underwater communication is presented, demonstrating efficient data transmission and resilience against noise and signal loss by performing semantic compression and prioritization of image data. These innovations collectively illustrate the broad impact of Al technologies, shaping strategies, and enhancing applications across various fields.

报告摘要：
There are three waves of Artificial Intelligence, The first Wave of AI is Crafted Knowledge, which includes rule-based AI systems. The second wave of AI is Statistical Learning, which includes machine becoming intelligent by using statistical methods. The third wave of AI is contextual adaptation. In the third wave, instead of learning from data intelligent machines will understand and perceive the world on its own, and learn by understanding the world and reason with it. Neurosymbolic Al, which combines neural networks with symbolic representations, has emerged as a promising solution of the third wave of AI. In this talk, I will my perspective on the emerging area.

报告摘要：
The mutual needs and benefits of Al and cybersecurity have been widely recognized. AI techniques are expected to enhance cybersecurity by assisting human system managers with automated monitoring, analysis, and responses to adversarial attacks. Conversely, it is essential to guard AI technologies from unintended uses and hostile exploitation by leveraging cybersecurity practices. The interplay between AI/machine learning, and cybersecurity introduces new opportunities and challenges in the security of AI as well as AI for cybersecurity. In this talk I will present my perspective on AI for cybersecurity and the security of AI.

报告主题：Digital Twin Enhanced Federated Reinforcement Learning with Lightweight Knowledge Distillation in Mobile Networks

报告摘要：
In this study, in order to facilitate the lightweight model training and real-time processing in high-speed mobile networks, we design and introduce an end-edge-cloud structured three-layer Federated Reinforcement Learning (FRL) framework, incorporated with an edge-cloud structured DT system. A dual-Reinforcement Learning (dual-RL) scheme is devised to support optimizations of client node selection and global aggregation frequency during FL via a cooperative decision-making strategy, which is assisted by a two-layer DT system deployed in the edge-cloud for real-time monitoring of mobile devices and environment changes. A model pruning and federated bidirectional distillation (Bi-distillation) mechanism is then developed locally for the lightweight model training, while a model splitting scheme with a lightweight data augmentation mechanism is developed globally to separately optimize the aggregation weights based on a splitted neural network structure (i.e., the encoder and classifier) in a more targeted manner, which can work together to effectively reduce the overall communication cost and improve the non-IID problem.

报告主题：Visual Sensing for Human-Machine Interaction

地 点：工科E1716
报告摘要：
With the increasing demand of machine intelligence across a wide range of application scenarios, human-machine interaction (HMI) emerges as another essential communication, whereby facial-expression-aware is one of the principal features for natural interaction. The principal branch of research in my group has been driven by the understanding of facial expression and the causative mechanism of emotion combining knowledge of visual computing with multiple disciplines, such as cognitive computing, as well as machine learning. Multimodal information including visual and biometric signals can record the facial muscle activity or brain activity closely related to facial movements and the internal emotional states. These multiple sensing channels would help provide an insight into the emotion and perception of facial expression, to develop widely accessible HMI solutions able to track facial motions and recognise affective states in a highly efficient and precise manner. I will discuss the development of visual capture of facial expression along with multiple sensing technologies for affective analysis. This talk will also discuss research on the development and challenges of image/video clustering as well as our recent development on this topic.
