Talk Title: From Smart Sensing to Smart Living
Date: August 23, 2021
We live in an era in which our physical and personal environments are becoming increasingly intertwined and smarter due to the advent of pervasive sensing, wireless communications, computing, and control technologies. Indeed, our daily lives in smart cities and connected communities depend on a wide variety of cyber-physical infrastructures, such as smart city, smart energy, smart transportation, smart healthcare, smart manufacturing, smart agriculture, and so on. Alongside, the availability of wireless sensors, Internet of Things (IoT) and rich mobile devices are empowering humans with fine-grained information and opinion collection through crowdsensing about events of interest, resulting in actionable inferences and decisions. This synergy has led to the cyber-physical-social (CPS) convergence with human in the loop that exhibits complex interactions, inter-dependence and adaptations between the engineered/natural systems and human users with a goal to improve human quality of life and experience in smart living environments. However, huge challenges are posed by the scale, heterogeneity, big data, social dynamics, security, and resource limitations in sensors, IoT and CPS networks. This talk will highlight unique research challenges in smart living , followed by novel frameworks and models for efficient mobility management, data gathering and fusion, security and trustworthiness, and trade-off between energy and information quality in multi-modal context recognition. Case studies and experimental results from smart energy and smart healthcare applications will be presented. The talk will be concluded with directions for future research.

Talk Title: IoT Security
Date: September 13, 2021
The Internet of Things (IoT) paradigm refers to the network of physical objects or “things” embedded with electronics, software, sensors, and connectivity to enable objects to exchange data with servers, centralized systems, and/or other connected devices based on a variety of communication infrastructures. IoT makes it possible to sense and control objects creating opportunities for more direct integration between the physical world and computer-based systems. Furthermore, the deployment of AI techniques enhances the autonomy of IoT devices and systems. IoT will thus usher automation in a large number of application domains, ranging from manufacturing and energy management (e.g., SmartGrid), to healthcare management and urban life (e.g., SmartCity). However, because of its fine-grained, continuous, and pervasive data acquisition and control capabilities, IoT raises concerns about security, privacy, and safety. Deploying existing solutions to IoT is not straightforward because of device heterogeneity, highly dynamic and possibly unprotected environments, and large scale. In this talk, after outlining key challenges in IoT security and privacy, we will outline a security lifecycle approach to securing IoT data, and then focus on our recent work on security analysis for cellular network protocols and edge-based anomaly detection based on machine learning techniques.

Talk Title: Collaborative Machine Intelligence: Enabling Low-Power Pervasive AI
Date: September 20, 2021
Pervasive computing applications often assume a distributed sensing substrate, incorporating both personal (mobile & wearable) devices and an IoT infrastructure (including devices such as radar & vision sensors). To support real-time & sustainable machine intelligence that exploits the rapid growth in such sensor-generated data, there is a need to optimize the execution of AI/ML pipelines on such resource-constrained embedded devices. In fact, assuring adequate and ubiquitous availability of power to such devices remains the most serious resource bottleneck and requires advances on both the supply side (new forms of energy harvesting) and the demand side (new forms of ultra-low power inferencing). Through this talk, I shall describe how collaborative machine intelligence (CMI), where the sensing and inferencing pipelines on individual wearable and IoT devices collaborate in real-time, helps tackle this power challenge. First, I will describe work on advances in battery-less, or low-power sensing, enabled by such collaboration. Second, using an exemplar video surveillance application, I will describe how CMI can provide dramatic reductions in energy overheads, as well as improvements in accuracy. I shall conclude by describing the emergence of a “Cognitive & Collaborative Edge”, that evolves from its current focus on mere computation offloading to a platform for enabling such collaborative and trusted sense-making.

Talk Title: Wearable Brain-Machine Interface Architectures
Date: September 27, 2021
Wrist-worn wearable devices provide rich sets of pulsatile physiological data under various modalities and circumstances. An unexploited capability is that the pulsatile physiological time series collected by wrist-worn wearable devices can be used for recovering internal brain dynamics. Two design classes of closed-loop wearable brain-machine interface architectures related to cognitive stress for tracking arousal and fatigue states are presented. The methods are validated by analyzing experimental electrodermal activity and cortisol data as well as simulation studies in the context of cognitive-stress-related arousal and fatigue. Results demonstrate a promising approach for tracking and regulating neurocognitive stress through wearable devices. Since wearable devices can be used conveniently in one's daily life, wearable brain-machine interface architectures have a great potential to monitor and regulate one's neurocognitive stress seamlessly in real-world situations.

University of Arizona
Talk Title: Like by Hand: Improving Visual Exploration of Control Flow through Computing-Specific Layout and Interactive Visual Analytics Design
Date: October 4, 2021
Control flow graphs (CFGs), networks representing possible paths of execution, are used widely in areas of computing such as program analysis, security, and compilation. Visualizations of CFGs are typically used as an exploratory tool to aid understanding or verify, debug, or propose new methods that utilize CFGs. However, general graph drawing approaches can limit the utility of CFG visualizations, producing drawings that are difficult to interpret, especially as the graph grows in size and complexity. To improve the efficacy of CFG visualizations, we develop a layout approach that preserves and emphasizes computing-specific structures such as loops and functions in a manner similar to hand-drawn versions. We design two custom interactive visualization systems that combine these layouts with additional views and features. Finally, we develop a library for filtering and drawing CFGs to support future visualization needs.

Talk Title: Enterprise Federated Learning Challenges and Solutions
Date: October 18, 2021
A significant amount of published work in Federated Learning deals with challenge of what can be called consumer federated learning, where federated learning is done on information from consumer mobile phones. Consumer federated learning deals with challenges of learning when data is split into many large number of pieces. When we consider the enterprise scenario, the environment consists of data which is split into a smaller number of locations, usually caused by regulatory concerns. The challenges in federated learning in enterprise scenarios is very different from that of consumer federated learning, and requires a different class of solutions, In this talk, we discuss the challenges in both consumer and enterprise federated learning, and outlines some of the approaches to address those challenges.

Talk Title: The Impact of Transportation Networks, Vaccines, and Vaccine Hesitancy on Epidemic Spreading
Date: October 25, 2021
In this talk, we explore how networked compartmental models of epidemic processes combined with transportation data can be used to model the spread of COVID-19. We first employ a networked SEIR (susceptible-exposed-infected-recovered) model and present necessary and sufficient conditions for identifying the model parameters from data. We illustrate several shortcomings of traditional approaches by applying the identification results to COVID-19 testing and travel data from the Northeastern United States and use these inaccuracies as motivation for the latter parts of the talk. The last second of the talk focuses on the recent development of a networked SEIR model that incorporates population flow as the viral spread mechanism to capture infection transmission between sub-populations. We show, under reasonable assumptions, that the dynamics have a consensus-type behavior where in steady-state each sub-population has the same number of recovered individuals. Employing this model, we present several approaches for using travel restrictions as a control mechanism also coupled with a vaccination effort. We present some preliminary results on validation with real data from the state of Minnesota. We conclude the talk with some recent work that leverages the concept of carrying capacity to account for vaccine hesitancy and shows the negative effects vaccine hesitancy on the threshold behavior of the system.

Talk Title: Nonlinear Opinion Dynamics for Decision Making in Multi-agent Interactions
Date: November 8, 2021
I will discuss a recently proposed model of opinion dynamics and its use in decision making for multi-agent cooperative and strategic interactions. The model describes continuous-time opinion dynamics for an arbitrary number of agents that communicate over a network and form real-valued opinions on an arbitrary number of options about which they may receive payoffs or input from the environment. Many models in the literature update agent opinions using a weighted average of their neighbors’ opinions. This model instead applies a sigmoidal saturation function to opinion exchanges, which provides a naturally smooth limit on the influence of neighbors. It also makes the update fundamentally nonlinear: opinions form through a bifurcation yielding multistable agreement and disagreement, tunable sensitivity to input, flexible transition between patterns of opinions, and opinion cascades. I will show how to apply the opinion dynamics to design of efficient dynamic multi-agent task allocation and as a model of reinforcement learning in multi-agent finite games.

University of Illinois Chicago
Talk Title: Data Mining for the Relationship Among Consciousness, AI, and Coordination
Date: November 29, 2021
In this talk I will first review the basics of consciousness and argue that it is a fundamental building block of General Artificial Intelligence. Then I will argue that consciousness is achieved through some coordination mechanism. Finally, I will describe our work in connectomics that uncovers a yet-to-be-explained coordination mechanism in the human brain. The work uses an approach to data mine the brain from a novel perspective, namely traffic analysis. The results are unexpected in the sense that the movement of signals in the brain seems to be coordinated to follow some global optimization patterns as opposed to the anarchical system that would be favored by evolution.

Talk Title: Cryptography using Elliptic Curves
Date: December 6, 2021
Cryptography, or the science of secret writing, has a long history going back thousands of years. Until the wide availability of "computers for the masses" it was the exclusive province of governments and large businesses. Until the 1970's the standard way for accomplishing this was through a shared secret known as a private key. Diffie and Hellman changed all that with a system that used a public key, which didn't need to be kept secret for the encoder, and private key only in possession of the recipient. Their original proposal, however, was discovered to have a flaw which made it less secure than originally thought. In 1985, Miller and Koblitz independently proposed using a then obscure mathematical object, known as an Elliptic Curve as a means of repairing the flaw in the original proposal. In the ensuing time, its security has held up, and is now widely used as a basis for secure communications in the Internet. In this talk we'll introduce elliptic curve and show how they avoid the flaw in the original Diffie-Hellman proposal.
