The worldwide flourishing of the Internet of Things (IoT) in the past decade has enabled numerous new applications through the internetworking of a wide variety of devices and sensors. More recently, visual sensors has seen their considerable booming because they usually capable of providing richer and more versatile information. Internetworking of large scale visual sensors has been named Internet of Video Things (IoVT). IoVT has its own unique characteristics in sensing, transmission, storage, and analysis, which are essentially different from conventional IoT. These new characteristics of IoVT are expected to impose significant challenges to existing technical infrastructures. In this talk, an overview of recent advances in various fronts of IoVT will be introduced and a broad range of technological and system challenges will be presented.

Computing the entropy of a network has proved to be an elusive problem, with potentially enormous impact on the fields of machine learning, complex systems  and big data. In this talk I will present an overview of recent work that has shown how ideas from spectral graph theory and statistical physics can be brought to bare on the problem, yielding simple methods for computing network entropy. The topics covered include detecting anomalies in network time series, modelling the time evolution of networks and decomposing networks into frequently occurring substructures, referred to as motifs. I will furnish examples from the financial and medical domains to illustrate the application of these techniques.


Edwin R. Hancock holds a BSc degree in physics (1977), a PhD degree in high-energy physics (1981) and a D.Sc. degree (2008) from the University of Durham, and a doctorate Honoris Causa from the University of Alicante in 2015. From 1981-1991 he worked as a researcher in the fields of high-energy nuclear physics and pattern recognition at the Rutherford-Appleton Laboratory (now the Central Research Laboratory of the Research Councils). During this period,  he worked on high energy physics experiments at the Stanford Linear Accelarator Center (SLAC) providing the first measurements of charmed particle lifetimes. He also held adjunct teaching posts at the University of Surrey and the Open University. In 1991, he moved to the University of York as a lecturer in the Department of Computer Science, where he has held a chair in Computer Vision since 1998. He leads a group of some 25 faculty, research staff, and PhD students working in the areas of computer vision and pattern recognition. His main research interests are in the use of optimization and probabilistic methods for high and intermediate level vision. He is also interested in the methodology of structural and statistical and pattern recognition. He is currently working on graph matching, shape-from-X, image data.

Point cloud data arise from depth sensing and capturing for both auto driving/navigation/smart city, as well as content capture and VR/AR playback applications. Recent advances in sensor technology and algorithms, especially 77Ghz MIMO radar systems, and high resolution structured light in conjunction with very high resolution RGB camera arrays, have made point cloud capture getting closer to real world applications. In this talk I will overview the related research at the Multimedia Computing & Communication Lab at UMKC, in conjunction with our industry partners for the auto driving thrusts at the new NSF Center for Big Learning, and discuss the main technical challenges in point cloud capture, compression and communication for auto driving and smart city applications,  especially the static and dynamic geometry compression, as well as attributes compression problems, and the new graph signal processing tools that can bring new coding efficiency. Some initial results will be presented and discussed, as well as the MPEG Point Cloud Compression call for proposal and results.

Interface of statistics, computing, and data science

Inference (aka predictive modeling) is in the core of many data science problems. Traditional approaches could be either statistically or computationally efficient, however not necessarily both. The existing principles in deriving these models – such as the maximal likelihood estimation principle - may have been developed decades ago, and do not take into account the new aspects of the data, such as their large volume, variety, velocity and veracity. On the other hand, many existing empirical algorithms are doing extremely well in a wide spectrum of applications, such as the deep learning framework; however they do not have the theoretical guarantee like these classical methods. We aim to develop new algorithms that are both computationally efficient and statistically optimal. Such a work is fundamental in nature, however will have significant impacts in all data science problems that one may encounter in the society. Following the aforementioned spirit, I will describe a set of my past and current projects including L1-based relaxation, fast nonlinear correlation, optimality of detectability, and nonconvex regularization. All of them integrates statistical and computational considerations to develop data analysis tools.
