Three issues are usually associated with large sensor network based intelligent surveillance systems. First, the collection, analysis, fusion and interpretation of a large amount of incomplete and heterogeneous information. Second, the demand of effectively predicting suspects’ intentions and ranking the potential threats posed by each suspect. Third, strategies of allocating limited security resources (e.g., the dispatch of security team) to prevent a suspect’s further actions towards critical assets. In this talk, I will present a multi-agent based event reasoning framework that can detect, correlate and reason with elementary events to predict potential threats. Game theory is then applied to select best strategies to allocate security resources based on threat degrees and suspects’ intentions.
Prof. Liu will also take this opportunity to give an overview of major research topics and future research directions in the Knowledge and Data Engineering Cluster, within the School of Electronics, Electrical Engineering and Computer Science, Queen’s University Belfast.
Prof. Weiru Liu holds the Chair of Artificial Intelligence, and is the Director of Research of the Knowledge and Data Engineering Cluster in the School of EEECS at QUB. Her research interests include noisy and uncertainty information modeling and fusion for sensor networks with applications to cyber and physical security, smart homes; intelligent autonomous systems, especially on agent’s belief revision with uncertain observations; game-theoretic resource management in multi-agent systems; and large-scale data analytics with particular focus on anomaly detection. She has over 140 publications, was the Conference and Program Chair of the 11th European Conference on Symbolic and Quantitative Reasoning under Uncertainty (ECSQARU’2011), was Program Co- Chair of 7th Int. Conf. on Scalable Uncertainty Management (SUM’2013). Her research has been supported by UK EPSRC, UK ESRC, UK TSB, the Royal Society, EU, and industry with total funding value over £17Million (projects of which she was/is either Principal Investigator or Co-Investigator) and had won EPSRC QUB Research Impact Award in 2011.
