The input-output approach for social optimization problems: Uncovering decentralized and selfish optimality
Abstract: We present an input-output approach to enhance the study of cooperative multiagent optimization problems that admit decentralized and selfish solutions, hence eliminating the need for an interagent communication network. The framework under investigation is the one used in standard Mean Field games: a set of N independent agents coupled only through an overall cost that penalizes the divergence of each agent from the average collective behavior. This type of social optimization problems can be related to a variety of applications including stock market, production engineering, dynamic demand management, population dynamics, pricing, consensus, swarm connectivity, etc. We show that optimal decentralized and selfish solutions are possible in a variety of standard input-output cost (norm) criteria, in some cases regardless of the population size N, and in some others asymptotically as N grows large.

Learning in Cyberphysical Systems
Abstract: Cyberphysical Systems (CPS) are very large networks of “smart” devices (possessing sensing, communication, and computation capabilities), that control physical entities. Notable examples enlist Smart Cities, Smart Grids, Intelligent Transportation, Sensor Networks, and Swarm Robotics. This keynote talk will comprise two parts: In the first part, we will present two methods for real-time learning in CPS: a) Sparse Kernel Density Estimation (S-KDE), with application in online estimation of travel time densities in transportation systems, and b) Sparse Matrix Decomposition (S-MD), applied to online detection and localization of forced oscillations in smart grids. The second part will highlight the fundamental balance between data transformation and data utility in machine learning. In Big Data applications, a key challenge lies in the fact that the data are hardly ever available in their original form, e.g., due to compression, anonymization, encryption, or right protection. We will showcase methods for exact learning from inexact data, with provable fidelity guarantees, in specific: a) Optimal distance estimation of compressed data series b) Nearest Neighbor preserving watermarking c) Cluster preserving compression, and d) Distributed consensus on encrypted data.

High-Dimensional State Estimation for Space Science
Abstract: The accelerating volume of information generated from ever less expensive sensing and processing technology is transforming all disciplines concerned with empirical determination. The space science community, with its ever expanding fleet of spacecraft and ground instrumentation, is now positioned to take advantage of the “big data” revolution. In this seminar, I describe how data assimilation, the systematic Bayesian inference of a high-dimensional state given a huge data volume and physical constraints on system dynamics, yields a deeper scientific characterization for the potentially destructive space weather phenomena facing our increasingly technological society. Attention is given to Kalman filtering and system identification methodological foundations and computational challenges faced when confronted with enormous data volumes.

Boolean Gossip Networks
Abstract: We propose and investigate a Boolean gossip model as a simplified but non-trivial probabilistic Boolean network. With positive node interactions, in view of standard theories from Markov chains, we prove that the node states asymptotically converge to an agreement at a binary random variable, whose distribution is characterized for large-scale networks by mean-field approximation. Using combinatorial analysis, we also successfully count the number of communication classes of the positive Boolean network explicitly in terms of the topology of the underlying interaction graph, where remarkably minor variation in local structures can drastically change the number of network communication classes. With general Boolean interaction rules, emergence of absorbing network Boolean dynamics is shown to be determined by the network structure with necessary and sufficient conditions established regarding when the Boolean gossip process defines absorbing Markov chains. Particularly, it is shown that for the majority of the Boolean interaction rules, except for nine possible nonempty sets of binary Boolean functions, whether the induced chain is absorbing has nothing to do with the topology of the underlying interaction graph, as long as connectivity is assumed.

Robotics and Computer Vision for Smart Surgical and Biomedical Applications
Abstract: Robotics and Computer Vision have profound impact on the advancement of medicine by equipping modern surgical procedures with unprecedented dexterous, visual and informational augmentations. Minimally invasive surgeries are examples that benefit from innovative imaging and robot-assisted technologies. In the talk, I will present my research that incorporates Robotics and Computer Vision to improve treatment procedures. This research encompasses the registration of pre-operative surgical plans with robotic systems as well as the enhancement of intra-operative images. A self-contained image mapping framework for 3D ultrasound image-guided endoscopic procedures developed to equip surgeons with an intuitive visualization of the vascular network will be presented. This example demonstrates the application of Computer Vision in overcoming the limitations of conventional intra-operative imaging methods. The talk will end with a look at a potential research on interactive robotic systems for surgical simulation and training.

Bearing Rigidity Theory and its Applications for Control and Estimation of Network Systems
Abstract: This talk will introduce my recent research results on distributed control and estimation over robotic networks. In particular, I will introduce a new bearing-based approach to solve some problems that used to be difficult to solve by conventional approaches. This bearing-based approach, which was originally motivated by vision-based multi-robot swarming, fully explores the critical role of bearing (or called direction) information in multi-robot control and estimation. With this approach, distributed formation control of multiple robots can be achieved merely based on inter-neighbor bearing measurements while distance information is not required. The bearing-based approach can also be applied to sensor network self-localization with bearing-only measurements and provide a simple solution to control the scale of multi-robot formations to avoid obstacles.
