Tim Havens Presents Talk at Technological University of Eindhoven

Timothy HavensICC Director Tim Havens (DataS) presented an invited talk, “Explainable Deep Fusion,” at the Technological University of Eindhoven, The Netherlands, on May 7, 2019.

Like a winning trivia team, sensor fusion systems seek to combine cooperative and complementary sources to achieve an optimal inference from pooled evidence. In his talk, Havens introduced data-, feature-, and decision-level fusions and discussed in detail two innovations he has made in his research: non-linear aggregation learning with Choquet integrals and their applications in deep learning and Explainable AI (XAI).

Inspiring the Next Generation of Cyber Stars

We live in a world where pretty much everything and everybody – individuals, companies, governments, critical infrastructure – are increasingly dependent on connected systems, networks and devices. And, as newspaper headlines reveal, those systems may be insecure and vulnerable to hackers.

“Nowadays, everybody is using computers, and more and more things are connected. That provides convenience, flexibility, a lot of great things, but it also opens the doors for hackers,” says Yu Cai, associate professor and program chair for the Computer Network and System Administration program at Michigan Technological University.

“The world has increasingly become a combination of the physical world and the cyber world,” Cai adds. “That’s why cybersecurity is important, because you want to protect yourself. As human beings, we evolved over thousands of years to take care of our security in the physical world. But in the cyber world, many don’t have a very good idea of how to protect themselves.”

Cai is principal investigator on two grant awards, each for about $85K, which are making possible two free, non-residential, week-long GenCyber summer camps on Michigan Tech’s campus. The first camp, for middle school and high school students, is the week of June 17. The second camp, for K-12 STEM teachers, is the week of August 12. Both camps and all learning materials are offered at no cost to camp participants. Each participant will receive a Raspberry Pi minicomputer. Breakfast and lunch are provided. For enrollment information, visit mtu.edu/gencyber.

Funded jointly by the National Security Agency (NSA) and the National Science Foundation (NSF), the goals of the nationwide GenCyber program are to increase interest in cybersecurity careers and diversity in the national cybersecurity workforce, help students understand correct and safe on-line behavior and how they can be good digital citizens, and improve teaching methods for delivery of cybersecurity content in K-12 curricula.

“This is part of our picture to make Michigan Tech a leader in cybersecurity research and education,” Cai says of this summer’s GenCyber camps. “We have other cybersecurity curriculum development grants that focus on college education, now we want to outreach to K through 12.”

In both camp sessions, participants will explore the world of cybersecurity through real-world case studies, hands-on learning activities and games, interactive lectures, career exploration, and field trips. Covered topics include safe online behavior, cyber ethics, fundamental computer and network knowledge, and cybersecurity career options and educational opportunities.

“We’ll also cover common vulnerabilities and weaknesses of computer systems, such as how hackers get into the systems, and how systems can be strengthened to defeat hackers against the hundreds of vulnerabilities,” Cai adds.

Tim Van Wagner, a lecturer at Michigan Tech and a co-PI on the grants, is the lead teacher for the camps. Cai and his other co-PIs—associate professor Guy Hembroff and assistant professor Bo Chen—will also present learning modules and assist with the camps.

K-12 pedagogical expertise in curriculum development was provided by Copper Country Intermediate School District (CCISD) staff members Emily Gochis, Director of the Region 16 MiSTEM Network, and Steve Kass, Educational Technologist.

“Steve and Emily provided a lot of input and suggestions regarding the camp curriculum and advised us in the best practices for teaching high school students,” Cai says, adding that they are also helping to promote the camps in local public schools.

Driving the curriculum are four principles: Learning by Storytelling, Learning by Doing, Learning by Gaming, and Learning by Teaching. Cai and his team will be assessing the effectiveness of these principles using several methods. The resulting research will be shared with the GenCyber program and the public.

The two grants are titled, “Innovative GenCyber Learning Experience for K-12 Teachers Through Storytelling + Teaching + Gaming + Doing” and “Innovative GenCyber Learning Experience for High School Students Through Storytelling + Teaching + Gaming + Doing.”

Tim Havens Is Co-author of Article Published in IEEE Transactions on Fuzzy Systems

Abstract: Information fusion is an essential part of numerous engineering systems and biological functions, e.g., human cognition. Fusion occurs at many levels, ranging from the low-level combination of signals to the high-level aggregation of heterogeneous decision-making processes. While the last decade has witnessed an explosion of research in deep learning, fusion in neural networks has not observed the same revolution. Specifically, most neural fusion approaches are ad hoc, are not understood, are distributed versus localized, and/or explainability is low (if present at all). Herein, we prove that the fuzzy Choquet integral (ChI), a powerful nonlinear aggregation function, can be represented as a multi-layer network, referred to hereafter as ChIMP. We also put forth an improved ChIMP (iChIMP) that leads to a stochastic gradient descent-based optimization in light of the exponential number of ChI inequality constraints. An additional benefit of ChIMP/iChIMP is that it enables eXplainable AI (XAI). Synthetic validation experiments are provided and iChIMP is applied to the fusion of a set of heterogeneous architecture deep models in remote sensing. We show an improvement in model accuracy and our previously established XAI indices shed light on the quality of our data, model, and its decisions.

Power Grid, Powertrain and the Models that Connect Them

Bo ChenGraduate students Chong Cao and Joe Oncken work with researcher Bo Chen (CPS/ME-EM) in the Intelligent Mechatronics and Embedded Systems lab. In the lab, they develop Simulink models for smart city technology — and show how the models shift into real-life testing.

“We develop and validate the controls in our process using a simulation first,” Cao explained, to which Oncken added: “Simulink is just an on-computer simulation software that’s all visual — you put building blocks together — and make an entire model of an electric car, the electrical grid.”

Bo Chen is the Dave House Professor of Mechanical Engineering and Electrical Engineering. Joe Oncken is PhD Graduate Research Assistant in the Department of Mechanical Engineering – Engineering Mechanics; Chong Cao is a PhD Graduate Research Assistant in the Department of Electrical and Computer Engineering.
