AI's future discussed at roundtable Rena Malai Tue, 06/13/2023 - 15:36

Just what is AI? 

This was one of the first questions posed by Missy Cummings, director of ��ӽ紫ý’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.

Washington Post quotes Missy Cummings on Tesla's Autopilot Rena Malai Mon, 06/12/2023 - 13:11

A Washington Post article titled '17 fatalities, 736 crashes: The shocking toll of Tesla's Autopilot' quotes Missy Cummings, director of ��ӽ紫ý's Autonomy and Robotics Center, on the troubling surge in Tesla crashes.

"Tesla is having more severe — and fatal — crashes than people in a normal data set,” she said in response to the figures analyzed by The Post.

One likely cause, she said, is the expanded rollout over the past year and a half of Full Self-Driving, which brings driver-assistance to city and residential streets.

“The fact that … anybody and everybody can have it. … Is it reasonable to expect that might be leading to increased accident rates? Sure, absolutely.”

She says in the article the number of fatalities compared to overall crashes was also a concern.

Twice a year, university teams compete in the Lighter Than Air (LTA) Defend the Republic competition. In April, ��ӽ紫ý 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.

��ӽ紫ý is hosting a competition of lighter than air (LTA) robotic agents—“blimps,” colloquially—squaring off in the heights of EagleBank Arena on Friday, April 28, from noon to 2 p.m.

The “Defend the Republic” competition features teams from six universities competing in a series of events where aerial robots attempt to move balls through hoops suspended from the ceiling, while other robots try to thwart them. The purpose of the game and the research behind it is to develop the ability of LTAs to respond quickly in various situations where such a vehicle, with its ability to stay aloft for much longer than traditional aerial devices, is ideal – disaster recovery, reconnaissance, delivering aid, and more.

At the Friday session, as many as 50 robots will be simultaneously in the air, with students and faculty available to answer questions about their robots and research.

Faculty members Cameron Nowzari, Ningshi Yao, and Daigo Shishika serve as principal investigators and lead the group.

Missy Cummings, one of the country’s first female fighter pilots and director of Mason’s Center for Robotics, Autonomous Systems, and Translational AI, calls herself a tech futurist, charged with making tech work better and safer. In a conversation with Mason President Gregory Washington, Cummings is unflinching in her critique of AI’s strengths, weaknesses, and shortcomings, as well as that of humans. There is a lot to like about AI, Cummings says, but she calls out bad tech where she sees it, including in the vision systems of self-driving cars and Tesla’s Autopilot.

New College of Engineering and Computing professor Missy Cummings seeks to address challenges in artificial intelligence

New College of Engineering and Computing professor Missy Cummings seeks to address challenges in artificial intelligence Tama Moni Tue, 01/03/2023 - 14:27

As one of the U.S. Navy’s first female fighter pilots and an engineer, Mary “Missy” Cummings is accustomed to breaking barriers and solving problems. So, when the opportunity to develop a new interdisciplinary program in artificial intelligence (AI) at ��ӽ紫ý’s College of Engineering and Computing emerged, she didn’t hesitate.

Cummings wants to increase the public and workforce's understanding of AI and its limits.

For example, self-driving cars have proven to be much more difficult to launch safely than originally believed. Before coming to Mason, Cummings served as the senior safety advisor to the National Highway Traffic Safety Administration. She said that experience sparked her interest in a new program in the design and deployment of AI.

“I believe we have a national security crisis across the Department of Transportation, the Department of Defense, and many other government agencies,” Cummings said. “We have a genuine technical illiteracy problem. It's not that people can't understand AI. It's that people are just not being educated in how AI is constructed or in its limitations.”

Cummings encountered tech illiteracy problems earlier in her career while serving on the Defense Innovation Board.

“I saw the problem then, and now that I've been in the Department of Transportation, it's doubly reinforced my concern about people's limited understanding of AI,” she said.

Cummings wants industry and government employees to know how to ask the right questions about performance weaknesses and understand where to invest tax dollars.

She said she’s concerned the U.S. doesn’t have an effective workforce when it comes to understanding, managing, acquiring, evaluating, and testing AI. She wants people to learn about the right way for humans and AI to work together as well as to learn what is truly attainable and what is merely hype.

“I think traditional academia has a hard time accepting new areas, like a degree program in the design and deployment of AI. Older schools with more ingrained traditions struggle to embrace newer thinking,” she said. “I don't think Mason is like that. Dean Ken Ball and others at the College of Engineering and Computing as well as Mason’s president Gregory Washington have embraced these ideas.”

“Missy’s knowledge and experience surrounding AI are going to be a phenomenal asset to Mason,” Ball said. “Her ability to make connections between computer science, electrical, and mechanical engineering fields and leverage the strengths of each to improve our understanding of AI will be a game changer. We are thrilled she has decided to work with us.”

Cummings is proposing a new degree program in AI that will target engineering students as well as those in policy, law, and public health. “To navigate the world of AI students also need softer skills in policy, and maybe even ethics,” Cummings said.

"I find that Mason is far more flexible and more open to new ideas than older more entrenched schools. At Mason, people are willing to come together from the different colleges and schools to solve real complex sociotechnical problems," she said. "There's not one societal problem we have today that belongs to a sole discipline."

Her faculty appointment spans three departments—Computer Science, Mechanical Engineering, and Electrical and Computer Engineering. She will also be the First American Bank Endowed Chair and Director of the Center for Robotics, Autonomous Systems, and Translational AI. Cummings' scholarly work will include opportunities to work with Fuse at Mason Square faculty and partners. Fuse will launch in 2024.
