Talk Title: Some Thoughts and Possible Future Directions Regarding Software and Hardware Safety and Security
Date: April 24th, 2023 Time: TBD
Are there fundamental limitations on the safety, security, and timeliness of heterogenous cyber-physical systems? Why are there so few safety+security engineers? Why is it difficult for security engineers to design for safety and for safety engineers to design for security? Why are security and safety so challenging to teach and learn in the first place? This talk will address these topics to various degrees of depth, drawing from existing published work, preliminary ideas, and observations which have not yet been quantified, and suggest promising future directions for research.

Talk Title: Attribute-based Encryption Scheme for Secure Data Sharing
Date: March 2nd, 2023, 3:30 PM
Attribute-based encryption (ABE) is a prominent cryptographic tool for secure data sharing in the cloud because it can be used to enforce very expressive and fine-grained access control on outsourced data. The revocation in ABE remains a challenging problem as most of the revocation techniques available today, suffer from the collusion attack. The revocable ABE schemes which are collusion resistant require the aid of a semi-trusted manager to achieve revocation. More specifically, the semi-trusted manager needs to update the secret keys of non-revoked users followed by a revocation. This introduces computation and communication overhead, and also increases the overall security vulnerability. In this work, we propose a revocable ABE scheme that is collusion resistant and does not require any semi-trusted entity. In our scheme, the secret keys of the non-revoked users are never affected. Our decryption requires only an additional pairing operation compared to the baseline ABE scheme. We are able to achieve these at the cost of a little increase (compared to the baseline scheme) in the size of the secret key and the ciphertext. Experimental results show that our scheme outperforms the relatable existing SOA schemes.

Talk Title: Bridging the Digital Divide: Foundations of Next Generation Integrated Space-Air-Ground Communication Systems
Date: February 8th, 2023, 10:00 AM
Despite the revolution in communication technologies that was witnessed in the past decade, there is still a significant portion of the earth's population who falls out of today's wireless broadband coverage. While people who live in under-developed, disaster-affected, or rural areas remain in "wireless darkness," communities in megacities are also often experiencing below-par wireless connectivity due to increasing demand for wireless services. To provide high-speed, reliable wireless connectivity to those on the less-served side of the digital divide, as well as to crowded urban environments, airborne and satellite-based communication platforms can be deployed as promising solution to boost the capacity and coverage of existing wireless cellular networks (e.g., 5G and beyond). In this talk, we address some of the fundamental challenges that face the realization of integrated space-air-ground communication systems by developing new frameworks that weave together new concepts from communications, machine learning, and game theory. First, we focus on the problem of wireless-aware control and navigation for drones that are used as access points to provide connectivity to remote areas. In particular, we introduce a novel multiagent, reinforcement learning solution with meta learning capabilities that can be used to control the navigation of these aerial access points, allowing them to provide effective, on-demand coverage to distributed, dynamic, and unpredictable ground user requests. We show that, using value decomposition techniques and a meta training mechanism, the proposed low training overhead control framework is guaranteed to converge to a local optimal coverage for the users, under systems. In particular, we develop a novel exchange market-based framework that allows the integrated system to efficiently exploit its spectral resources while optimizing its communication performance in terms of data rates. We then show that the optimal. equilibrium allocation of resources can be found by using a lightweight, distributed solution that facilitates cooperative spectrum sharing in the integrated system and yields a faster convergence compared to a baseline sub-gradient algorithm. We conclude the talk with an overview on future, exciting research directions.

Talk Title: Quantum walk mixing with Chebyshev polynomials
Date: November 14, 2022
A quantum walk is the quantum analogue of a random walk. A long-standing open question is whether quantum walks can be used to quadratically speed up the mixing time of random walks. We describe a new approach to this question that builds on the close connection between quantum walks and Chebyshev polynomials. Specifically, we use that the quantum walk dynamics can be understood by simply applying a Chebyshev polynomial to the random walk transition matrix. This decouples the problem from its quantum origin, and highlights connections to classical second-order methods and the use of Chebyshev polynomials in random walk theory as in the Varopoulos-Carne bound. We illustrate the approach on the lattice: we prove a weak limit on the quantum walk dynamics, giving a different proof of the quadratically improved spreading behavior of quantum walks on lattices.

Talk Title: Federating Cyber-Physical Systems
Date: November 7th, 2022
It is predicted that with the advances made in the Internet-of-Things, Next Generation Networking, Cloud computing and Artificial Intelligence, hundreds of thousands of islands of Cyber Physical Systems (CPS) which are currently geographically distributed in different countries and regions worldwide, as well as in different locations in cities, will be federated to generate unprecedent datasets which, when submitted to emerging artificial intelligence models (e.g. machine learning), will provide solutions to some of the key problems that the world could not solve till today. This is the case, for example, in the emerging field of virtual/soft sensing, where artificial intelligence techniques are used to complement Internet-of-Things (IoT) measurements to provide innovative and more practical and economical solutions to many of the issues the world is currently facing. However, the digital divide between developed and developing nations, leading to an imbalance in cloud processing resources, is a key issue that might jeopardize/hamper the development of such CPS federations. This talk focuses on the design and performance evaluation of Federated Cyber-Physical Systems (FCPS), with the objective of showcasing how a federated cloud computing (FCC) model can be used to build data-intensive ecosystems. Building on a use-case, the talk reveals that through federation and cooperative sharing of cloud resources, a cloud computing system can be built and used to improve the quality of service delivered by data-intensive processing infrastructures across a continent. The details of a Federated Cloud Computing Infrastructure (FCCI) called “AFRICA 3.0” aiming at fostering the Fourth Industrial Revolution (4IR) on the African continent will be presented and discussed during the talk.

Talk Title: Searches with Quantum Walks
Date: October 31, 2022
Random walks serve as the basis of a number of algorithms, and this led to the idea that perhaps a quantum version of a random walk would be useful for finding quantum algorithms. Constructing a quantum walk is not completely straightforward, and there are three ways of doing it, two of which will be discussed in this talk. They have proved useful in search problems, where there is a distinguished vertex in a graph, and we would like to find it. It is also possible to search for other objects, such as extra edges or more general structures that break the symmetry of a graph. Most recently, it has been possible to use quantum walks to find paths between two special vertices, which is analogous to using them to find a path though a maze.

Talk Title: Neural Collapsed Representation in Deep Learning Classifiers
Date: October 24, 2022
In the past decade, the revival of deep neural networks has led to dramatic success in numerous applications ranging from computer vision to natural language processing to scientific discovery and beyond. Nevertheless, the practice of deep networks has been shrouded with mystery as our theoretical understanding of the success of deep learning remains elusive.
In this talk, we will focus on the representations learned by deep neural network classifiers. In this setting, the recent work by Papyan et al. revealed an intriguing empirical phenomenon, called neural collapse, that persists across different neural network architectures and a variety of standard datasets. We will first provide a geometric analysis for understanding why neural collapse always happens on a simplified unconstrained feature model. We will then exploit these findings to understand the roles of different loss functions proposed in the literature for training deep neural networks. Among all the proposed loss functions, which one is the best to use is still a mystery because there seem to be multiple factors affecting the answer, such as the properties of the dataset, the choice of network architecture, and so on. Through the principles of neural collapse, we will show that all relevant losses produce equivalent features on training data and lead to largely identical performance on test data as well, provided that the network is sufficiently large and trained until convergence.

Talk Title: Data-Driven Smartphone Localization with Zero Infrastructure
Date: October 17, 2022
The early suppression of fires on ro-ro vessels requires rapid fire identification as a fire of medium growth exponentially reaches 50kW after only 1 minute. Fire patrol members (e.g., able seamen) are asked to act as first responders in such fire incident cases. They do however lack the necessary digital technology for immediate localization, verification and coordination with the bridge and other first responders. Indoor localization requires dense referencing systems (such as Wi-Fi, UWB, Bluetooth antennas), but these technologies require expensive installations and maintenance. Also, Satellite-based indoor localization is obstructed by the bulky steel structures of vessels, so this doesn’t work either. In this work we develop a ground-breaking localization technology that requires zero infrastructure using computer vision on commodity smartphone devices attached to the gear of first responders. The developed solution comprises of three steps: (i) Training, where vessel owners supply video recordings that are processed on a deep learning data center to produce an accurate computer vision machine learning model; (ii) Logging, where a mobile app allows referencing non-movable objects to the (x,y,deck) coordinates of a vessel; and (iii) Localization, where first responders localize on a digital map. Additionally, in case a sparse communication network is available, first responders can share their location, emergency messages and heat scan images with nearby first responders and the bridge. Our proposed algorithm, coined Surface, is shown to be 80% and 90% accurate for localization and tracking scenarios, respectively, in both a remote study and an on-board study we carried out on a real ro-ro vessel. The overall developed Smart Alert System (SMAS), streamlines the lengthy fire verification, coordination, and reaction process in the early stages of a fire, improving fire safety. My talk will conclude with a summary of other relevant work in the scope of our open-source indoor localization system, named Anyplace.

Talk Title: Multimedia Big Data Analytics for Data Science and Introduction of dSAIC
Date: October 10, 2022
The idea of Data Science has gathered many different perspectives throughout different domains and articles. In this talk, Data Science is discussed as the theories, techniques, and tools designed for data-centered analysis and the methodology to apply them to real world applications. We have revolutionized the process of gathering multimedia data from an abundance of sources. Things such as mobile devices, social networks, autonomous vehicles, smart household appliances, and the Internet have increasingly grown in prominence. Correspondingly, new forms of multimedia data such as text, numbers, tags, networking, signals, geo-tagged information, graphs, 3D/VR/AR, sensor data, and traditional multimedia data (image, video, audio) have become easily accessible. Therefore, older traditional methods of processing data have become increasingly outdated, emphasizing the demand for more advanced data-science techniques to process these heterogeneous, large data sets which fluctuate in quality and semantics. Additionally, the inconsistency of utilizing single modality severely hinders our ability to withstand multiple data sources simultaneously. Upon analyzing the capabilities of each model, it becomes pivotal for us to consider the multi-modal frameworks to leverage the multi-data sources to assist data analytics. With the implementation of data science and big data strategies, we are able to efficiently capture, store, clean, analyze, mine, and visualize exponential growth of multimedia data, which is responsible for the majority of daily Internet traffic. With the data science field growing with importance, the goal of big data revolution is to bridge the gap between data availability and its effective utilization which enables research, technological innovation and even decision making. In this talk, I will discuss the research opportunities and challenges in multimedia big data for data science. A set of core techniques and applications will be discussed. I will also discuss Data Science and Analytics Innovation Center (dSAIC) - a University of Missouri System-wide Center.
