Just what is AI? 

This was one of the first questions posed by Missy Cummings, director of George Mason University’s Autonomy and Robotics Center, at the Future of AI roundtable in June. 

“At the end of the day, AI can be a tool to help you in your job, but you need to understand both its strengths and weaknesses,” Cummings said. “That’s why Mason will be offering a certificate and master’s degree focused on responsible AI, so that people across industry and government can learn how to manage the risks while promoting the benefits of AI.”

The invite-only roundtable, hosted by the College of Engineering and Computing, explored the issues, challenges, and solutions to think about as AI technologies rapidly evolve and change almost as soon as they are introduced. 

Missy Cummings leads the Future of AI roundtable at Mason Square.

Cummings led the roundtable and highlighted AI areas like ChatGPT and autonomous driving systems that lack human reasoning skills. When human behavior, environment, and AI blind spots intersect, the resulting uncertainty contributes to fundamental limitations. 

“As humans, we do a great job of successfully filling in the blanks when there is imperfect information,” said Cummings. “If I quickly flash a picture of a stop sign, your brain automatically recognizes what it is, even if it’s not a clear image. But it’s arguable whether the vision system on a self -driving car can do the same.” 

She added that automation can fall apart at a critical threshold, such as when a car is supposed to stop at a stop sign that’s visible to the human eye, but maybe overlooked by an AI vision system. 

“As humans, we have much more experience driving cars,” she said. “Self-driving cars are still a new technology and while simulation testing can help identify problems, real-world testing for such non-deterministic systems that never reason the same way twice is critical.”

One of her favorite uses of ChatGPT is for her students to use it for grammar and spell checking when they write papers, but that’s the extent.  

“ChatGPT cannot reason under uncertainty. It does not think. It does not know. It can approximate human knowledge, but there is no actual thinking or knowledge,” said Cummings. “ChatGPT goes after the most probable image, or the most probable grouping of words.” 

In general, large language models like ChatGPT will use what the average person is saying on the internet. This means it could pick up extremist views, if it is currently something trending or popular online.    

It can also be a concern when it comes to diversity, she said. 

“If a company uses ChatGPT to write their mission statement, in another five years, everyone’s mission statement will be the same,” Cummings said. “Creative thoughts and authenticity are lost. It’s important to understand how far we push these models, and what the long-term ramifications could be.”

Roundtable attendees from local universities and tech companies left with a greater understanding of how AI can impact everyday life, in more ways than one.

Twice a year, university teams compete in the Lighter Than Air (LTA) Defend the Republic competition. In April, George Mason University hosted the competition in EagleBank Arena and won. The winning Mason team, Patriot Pilots, led by principal investigators Cameron Nowzari, Ningshi Yao, and Daigo Shishika, all from the College of Engineering and Computing, competed against six universities and about 50 LTA robotic agents, aka blimps.

“Even after three years, I’m still in awe of what happens at this competition,” said Nowzari, who has led the competition for the past three years, will be moving on from the annual competition and leaving things in the hands of Yao and Shishika. “My hope is that this competition will continue, and more schools will get involved.”

The competition is a mix of technology and creativity, and something students seem to have a lot of fun with, according to Yao.

“The strength of our winning team was in the ability to think creatively through building and design,” said Yao.

Without the severity that can sometimes accompany other types of flying agents, blimps are a lighter, gentler kind of airborne machine that appeals to many people.

“Their soft body and low operational speed make them more tangible and accessible than drones or planes,” said Shishika. “At the same time, they bring unique and exciting research challenges that our students with diverse background tackle together.”

The team will schedule a kickoff meeting during the summer, to plan for the next competition in November. The team welcomes students from all majors.

“We’re always actively recruiting for the team,” Nowzari said. “All that you need to bring is your passion and creativity.”

For information on how to join, email dshishik@gmu.edu or nyao4@gmu.edu. People can also visit blimp-robotics.org to learn how to build their own LTA blimp and encourage younger students to do the same.

Mason ECE graduate student gets SMART

Mason ECE graduate student gets SMART Rena Malai Tue, 07/05/2022 - 13:00

Getting a Science, Mathematics, and Research for Transformation (SMART) scholarship isn’t easy, but it’s a gainful step toward building a career of growth, enrichment, and opportunities within the U.S. government.

Sabrina Stenberg sees the SMART scholarship as a way to maximize her graduate studies at George Mason while remaining employed as a chemical engineer with the Department of Defense (DoD). Through the scholarship, Stenberg can focus on her master of science in electrical engineering at Mason full-time.

Stenberg says the scholarship is funded by DoD with the aim of attracting and retaining people into STEM careers at the government level.

“I am really happy to win this scholarship,” says Stenberg. “This way I can finish in three more semesters and make the most of the experience, connecting with other students and my professors.”

Stenberg, a Northern Virginia native, says the scholarship is not a one stop source of money. Rather, it requires commitment and accountability so anyone thinking of applying should be prepared.

“People should be mindful that this scholarship does have conditions,” says Stenberg. “You will be expected to commit to your program of study, keep up your grades, and agree to fulfill the one-to-one scholarship for service time commitment with DoD for every year of funded study. Any withdrawals can result in penalties, like paying back your tuition.”

She feels the conditions are worth it, as it will open up the doors to plenty of great job opportunities.

“In my current job, I became more interested in electronics and I decided to combine that interest by studying control and robotics,” says Stenberg. “It’s a valuable area to learn about as there are a lot of autonomous systems within the military.”

Although Stenberg was already employed by DoD, anyone interested in SMART does not have to be employed before applying. Potential applicants do need to be at least 18 years old, a U.S. citizen, have a high GPA, and be able to accept employment with DoD after graduating.

The SMART program, part of the DoD science, technology, engineering, and mathematics portfolio provides STEM students with the tools needed to pursue higher education and begin a rewarding career with the DoD. Scholarship winners can receive full tuition as well as a stipend and full-time employment after graduation.
