Talk Title: Merely Fun with Algorithms
Date: January 24, 2022

In this talk, we will design and analyze "cool" algorithms (that are elegant and efficient) for simple practical problems yet of recreational nature. Emphasis will be given on fundamental concepts discussed in an interactive manner. Afterall the goal is to have fun!!


“... pleasure has probably been the main goal all along. But I hesitate to admit it, because computer scientists want to maintain their image as hard-working individuals who deserve high salaries. Sooner or later society will realize that certain kinds of hard work are in fact admirable even though they are more fun than just about anything else.”

Dr. George Markowsky | Professor of CS

Missouri S&T 
Talk Title: Lanchester’s Differential Equations and Cyberwarfare 
Date: January 31, 2022

In his classic book Aircraft in Warfare, F. W. Lanchester discussed different types of warfare and presented equations, called the Lanchester equations, that can be used to model the results of battles between two forces of different sizes or capabilities. This paper introduces the Lanchester equations and provides a theoretical discussion leading to an analysis of the relative value of increasing the effectiveness of military assets vs. increasing the quantity of those assets. In particular, we show that increasing the effectiveness contributes only linearly to the power of a combatant, but increasing the quantity contributes quadratically. This talk also presents a Python script that models the Lanchester equations, together with a visualization demonstrating the effect of force concentration. The talk concludes with a discussion of the relevance of Lanchester’s equations to cyberwarfare, specifically to drone warfare and DDoS attacks. More generally, we provide a foundation for analyzing the tradeoff between quality and quantity in warfare.

Talk Title: Optimal and Approximation Algorithms for Multiple Drone-Delivery Scheduling Problem
Date: February 7, 2022

Time: 10-11 am Central time

Unmanned Aerial Vehicles (or drones) can be used for a myriad of applications, such as search and rescue, precision agriculture, last-mile package delivery, etc. Interestingly, the cooperation between drones and ground vehicles (trucks) can even enhance the quality of service. In this talk, we will investigate the symbiosis between a truck and drones in the last-mile package delivery, introducing the Multiple Drone-Delivery Scheduling Problem (MDSP). From the main depot, a truck transports a team of drones for delivery of packages to the customers. Each delivery is associated with a drone's energy cost, a reward that characterizes the priority of the delivery, and a time interval representing the launch and rendezvous times from and to the truck. The objective of MDSP is to find an optimal scheduling for the drones that maximizes the overall reward subject to the drone's battery capacity while ensuring that the same drone performs deliveries whose time intervals do not intersect. After proving that MDSP is an NP-hard problem, we will devise an optimal solution based on Integer Linear Programming (ILP), a heuristic algorithm for the single drone case and two heuristics for the multiple drone case. We will compare the performance of our algorithms.

Talk Title: Data Integration: The Forgotten Stepchild of Data Science
Date: February 14, 2022

Time: 10:00 AM CST

As the generation of data becomes more prolific, the amount of time and computational resources necessary to perform analyses on these data increases. What is less well studied, however, is the data pre-processing steps that must be applied before any meaningful analysis can begin. This problem of taking data in some initial form and transforming it into a desired one is known as data integration, and it can be a substantial part of the overall computational load associated with data analytics.  Our group is exploring the execution of data integration via a range of compute engines, including Field-Programmable Gate Arrays (FPGAs), Graphics Processing Units (GPUs), Near-Memory Processing (NMP) architectures, and mixed-mode analog/digital systems. Applications are drawn from computational biology, scientific experiments (astrophysics and nuclear science), enterprise systems, image processing, graph processing, and the Internet of Things (IoT).

Dr. Roger Chamberlain is Professor of Computer Science and Engineering at Washington University in St. Louis.  He completed his doctoral degree in computer science in 1989 from the same institution.

Talk Title: Towards High-Throughput Cryptocurrency Transactions in Payment Channel Networks
Date: february 21, 2022

Time: 10:00 AM CST

Scalability is one of the key issues that hinder the widespread use of cryptocurrencies, like Bitcoin, due to the underlying consensus algorithms for ensuring the security in a decentralized system. Recently, payment channel network (PCN) has been proposed as a promising off-chain solution. It allows instant and inexpensive payments by not requiring expensive and slow blockchain operations. However, to enable high-throughput transactions in PCNs, there are still many barriers to overcome, including transaction fee, node reliability, always-online requirement, balance depletion, and cryptocurrency utilization. In this talk, I will present some of our recent work on addressing these challenges. More specifically, I will first introduce two distributed algorithms for minimizing the transaction fee and providing robustness despite unreliable nodes, respectively. Next, I will demonstrate how to design smart contracts to deter the potential collusion in PCNs based on a game theoretic approach. Finally, I will share our thoughts on addressing other challenges.

Talk Title: Latent Privacy via a Secret Block Structure
Date: February 28, 2021

Time: 10:00 AM CST

Physical layer security approaches have often used the hardness of blind deconvolution to achieve privacy when transmitting signals over unknown wireless channels.  Herein, we exploit the communication channel in a new way to provide a layer of privacy. In particular, we take advantage of the fact that it has been shown that exact recovery of block-sparse signals via linear measurements is achievable under conditions where classical compressed sensing would provably fail. We exploit this result to propose a novel private communication framework where secrecy is enhanced by transmitting instances of an unidentifiable compressed sensing problem over a public channel. The legitimate receiver can attempt to overcome this ill-posedness by leveraging secret knowledge of a block structure that is used to encode the transmitter's message. We study the privacy guarantees of this communication protocol in a variety of cases with the goal of understanding how often we need to refresh the shared secret between the transmitter and intended receiver.  Additionally, we propose an algorithm for an eavesdropper to learn the block structure via the method of moments and highlight the privacy benefits of this framework through numerical experiments.

Talk Title: Chernoff Sampling for Active Testing and Extension to Active Regression 

Date: March 7, 2022

Time: 10:00 AM CST

Commonly used machine learning models are often trained on large datasets. As a result, a natural stumbling block in applying them more widely is the human effort required to label or annotate the data. Active learning is a framework that can reduce the number of labelled data needed to achieve a desired performance. In this talk, I will explain the benefit of active learning in two problem settings: active testing and active regression. In active testing, the sequential design of experiments developed by Chernoff in 1959 is widely used and known to be asymptotically optimal. We obtained a novel non-asymptotic bound on the number of labelled data needed for Chernoff’s algorithm. We will then look at an extension of the algorithm for active regression. In addition to obtaining a theoretical performance guarantee, we find that our extension requires fewer labelled data compared to existing methods in both simulated and real-world datasets.

Emory University

Talk Title: Trustworthy Machine Learning with Differential Privacy and Certified Robustness

Date: March 14, 2022

Time: 10:00 AM CST

While deep learning models have achieved great success, they are also vulnerable to potential manipulations, ranging from model inversion attacks that attempt to infer sensitive training data from trained models, to adversarial example attacks that create manipulated data instances to deceive a model. In this talk, I will present our recent work on achieving 1) differential privacy (DP) to ensure privacy of the training data and 2) certified robustness against adversarial examples for deep learning models. First, I will present a practical DP training framework with better empirical and theoretical utility (IJCAI’21) and an extended DP notion for more quantifiable protecting against model inversion attacks (BigData’20). Second, I will present a certified robustness approach via randomized smoothing for quantized neural networks (ICCV ’21). Finally, I will present a framework that kills two birds with one stone and achieves DP and certified robustness via randomized smoothing simultaneously.

Talk Title: Addressing Robustness and Fairness in Federated Learning
Date: March 21, 2022

Time: 10:00 AM CST

Federated Learning (FL) has received extensive attention from the research community because of its capability for privacy-preserving, collaborative learning from heterogeneous data sources. As the server cannot govern the clients’ actions, a nefarious client may attack the global model by sending malicious local gradients. Moreover, some clients, despite benign, may have unreliable data due to their heterogeneous hardware configurations and environments. Such unreliable clients can misguide the training process, resulting in a poorly fit model. Further, the performance disparities across clients in the presence of attacks have largely been unexplored.


This talk will first address the challenge of malicious client detection in federated learning under targeted and untargeted attacks. Additionally, we will introduce unreliable clients leading to another realistic yet challenging problem. As a solution, an innovative sequential approach will be proposed that will identify and mitigate the influence of both attackers and unreliable clients. Finally, we will introduce the problem of performance fairness and a solution to improve it across the clients.

Dr. Daphney-Stavroula Zois | Distinguished Seminar Speaker

University at Albany, State Univ. of New York

Talk Title: Dynamic Instance-wise Feature Selection for Real-Time Machine Learning

Date: April 4, 2022

Time: 10:00 AM CST

Feature selection is an important topic in machine learning, pattern recognition and data mining. Despite being an extensively studied problem, most existing approaches assume that the feature selection is conducted offline, and all the features of instances are provided a priori during testing. Such assumptions may not always hold for real-world applications in which features arrive sequentially or it is expensive to access all features at the same time. For instance, in an online social network, millions of messages are exchanged between users, making it difficult to employ a standard feature selection technique to identify harassment messages in a timely, efficient, and scalable manner. In this talk, I will introduce a novel mathematical framework that sequentially selects the number of features and the order by which they are reviewed for each data instance, before stopping and proceeding with a decision about the data instance. The proposed framework is guaranteed to reach an accurate decision by reviewing the optimum least number of informative features. I will demonstrate the performance of the proposed framework on a variety of benchmark datasets and discuss extensions in regression settings and structured environments.

Dr. Mahnoosh Alizadeh | Distinguished Seminar Speaker

University of California, Santa Barbara

Talk Title: Learning and Optimization Algorithms for Safe Demand Management

in Infrastructure Systems

Date: April 11, 2022

Time: 10:00 AM CST

This talk is motivated by the problem of learning to design dynamic prices/incentives for demand management in safety-critical infrastructure systems such as the power grid. Faced with uncertainty regarding how customers will respond to posted prices, we highlight the need for safety-aware bandit optimization algorithms for designing prices that control the probability of violation of system constraints in spite of uncertainty. Then, in the first part of the talk, we discuss how we can manage safety constraints in admittedly simpler stochastic bandit problems with affine constraints and provide formal regret guarantees. In the second part of the talk, we discuss how our theoretical insights can be generalized for safe and efficient price design in our motivating example of dynamic pricing in power systems.

Mr. Joe Weiss | Seminar Speaker

Industry Expert in Control System Security

Talk Title: “Shields-Up” and Good Cyber Hygiene Don't Apply to Insecure Process Sensors

Date: April 18, 2022

Time: 10:00 CST

Process sensors have no capability for passwords, multi-factor authentication, encryption, keys, signed certificates, etc.  Despite the lack of any cyber security, these devices are the 100% trusted input to OT networks and manual operation. Moreover, process sensors have no cyber forensics. We have a serious problem because the people responsible for the design and operation of equipment do not consider cyber security of interest, and the network security people who consider cyber security important do not consider process sensors or other engineering equipment important. Ironically on March 16, 2022 NIST issued NIST Special Publication 1800-10 Protecting Information and System Integrity in Industrial Control System Environments: Cybersecurity for the Manufacturing Sector. The NIST report states “It is acknowledged that many of the device cybersecurity capabilities may not be available in modern sensors and actuators.” Network cyber threats such as vulnerabilities in Log4j, the Treck TCP/IP Stack, and ransomware make off-line monitoring of process sensors more important than ever. This talk will present an overview of the current state of affairs in this important area.

Dr. Avah Banerjee | Seminar Speaker

Missouri University of Science and Technology

Talk Title: Non-Abelianess and Quantum Computing

Date: April 25, 2022

Time 10:00 CST

Non-Abelianess can be attributed to the hardness of many computational problems.  It also shows up when modeling certain quantum systems.  In some cases, it serves as an obstruction, creating barriers for efficient computational simulations. And yet, for others, non-Abelianess can be utilized, possibly developing more robust quantum computers. In this talk I will highlight three instances: 1) the non-Abelian hidden subgroup and the hidden shift problem and limitations of Fourier sampling, 2) propagation of quantum walks on non-abelian groups and their applications – some of our recent results, and 3) quest for non-Abelian anyons for building topological quantum computers. These topics span several areas including quantum physics, complexity theory, group theory etc. In the talk I will present the key insights at a high level and only a minimal knowledge in the above areas is assumed.
