In Stockholm for a series of Nobel Week events, the “godfather of AI” will officially accept his Nobel Prize in Physics at a ceremony on Dec. 10

The University of Toronto’s Geoffrey Hinton took to the stage at the Swedish Academy in Stockholm this weekend – two days before he officially accepts his Nobel Prize in Physics for fundamental work in AI – to deliver a lecture on the inventions and discoveries that led to him being given the prestigious award.

“Today, I’m going to do something very foolish – I’m going to try and describe a complicated technical idea for a general audience, without using any equations,” said Hinton, a ��ֱ�� University Professor emeritus of computer science, prompting laughter from the audience.

The “godfather of AI” then proceeded to outline how decades of his fundamental research, and that of his co-laureate John J. Hopfield of Princeton University, enabled the development of artificial neural networks and machine learning – technologies that underpin today’s AI revolution.

The Nobel lectures are among the highlights of Nobel Week, which runs from Dec. 6-12 in Stockholm and Oslo and includes award ceremonies, banquets, media engagements and commemorations at the Nobel Museum. There is also a series of Nobel Week events taking place at ��ֱ��, including watch parties on all three campuses for the livestream of the Dec. 10 award ceremony.

Sunday’s first Nobel Prize lecture in physics was delivered by Hopfield, who shared how his fascination with the workings of the human brain inspired his development of the Hopfield network – an associative memory that can store and reconstruct patterns in data.

“How mind emerges from brain is, to me, the deepest question posed by our humanity,” Hopfield said.

When it was Hinton’s turn to take the stage, he described how he and Terry Sejnowski – one of Hopfield’s students – came upon a novel use of Hopfield nets: “Instead of using them to store memories, we could use them to construct interpretations of sensory input,” Hinton said.

He then went on to discuss the resulting Boltzmann machine, a type of neural network that is capable of recognizing elements within data.

Yet, despite its promise, the original Boltzmann machine was too slow, Hinton said, and it wasn’t until several years later that he came up with “restricted Boltzmann machines,” which impose limitations on connections between neurons in order to increase system efficiency – a development that would prove pivotal in training deep neural networks (Hinton donated an early Boltzmann chip, about the size of a postage stamp, to the Nobel Prize Museum).

Following the lecture, Hinton was joined on stage by Hopfield, with the pair sharing a vigorous handshake and posing for photos.

Separately, ��ֱ�� convened an expert panel in Stockholm on Monday about the direction of AI research and development.

Moderated by Leah Cowen, ��ֱ��’s vice-president, research and innovation, and strategic initiatives, the panel included: Eyal de Lara, a professor and chair of the department of computer science in ��ֱ��’s Faculty of Arts & Science; David Lie, director of the Schwartz Reisman Institute for Technology and Society and a professor in the Edward S. Rogers Sr. department of electrical and computer engineering in the Faculty of Applied Science & Engineering; Tony Gaffney, president and CEO of the Vector Institute for Artificial Intelligence; and Amy Loutfi, professor of computer science and pro-vice-chancellor for AI at Örebro University in Sweden.

The conversation touched on areas including the promising applications of AI, how responsible deployment of AI can mitigate the technology’s potential pitfalls and implications of AI’s rise on education.

��ֱ�� President Meric Gertler said that the AI breakthroughs fostered by Hinton’s research were made possible by Canada’s longstanding support of basic research.

“Geoff was interested in the novel but unproven concept of artificial neural networks, an area that was sometimes described as the ‘unpromising backwater’ of AI research,” President Gertler said in his remarks introducing the panel, noting that Hinton joined ��ֱ�� in 1987 and was one of the first scholars to receive support from the Canadian Institute for Advanced Research (CIFAR).

“Canada was investing in brilliant people, their ideas and their students – and those investments have paid off many years later.”

Canada was also the first country to launch a national AI roadmap, President Gertler said, in the form of the Pan-Canadian Artificial Intelligence Strategy – which funds three national AI institutes including the Vector Institute for Artificial Intelligence, which is now housed in ��ֱ��’s new Schwartz Reisman Innovation Campus. The state-of-the-art building also hosts the Schwartz Reisman Institute for Technology and Society, which is at the forefront of research and thought leadership on AI safety and responsible development, with Hinton one of its advisory board members.

“In short, Canada has played a key role in launching and driving the AI revolution and we’re a world leader in understanding and promoting safe, human-centred AI,” President Gertler said.

The theme of responsible AI was also brought up during a Q-and-A with Hinton, who revealed that the remarkable information-sharing abilities of large language models played a big role in sparking his now oft-repeated concerns around the current pace of the technology’s development.

“That’s when I came to realize that the fact that they’re so much better at sharing probably means that digital intelligence is just a better form of intelligence than us – and that’s what got me so worried,” he said.

Asked what responsible AI regulation looks like, Hinton said there must first be a consensus around solving the problem from a scientific standpoint – not unlike the scientific consensus that has emerged around climate change.

“Like the early days of climate change, the first thing to do is figure out what’s causing it and get scientific agreement on how you can fix it. Then, the second thing to do is get the politicians to do something about it … but here, we haven’t finished the first thing yet.”

Known as the "godfather of AI," Hinton was one of five people honoured with the US$3-million prize awarded by Vietnam's VinFuture Foundation

Geoffrey Hinton, University Professor emeritus of computer science at the University of Toronto and winner of the 2024 Nobel Prize in Physics, has added another prestigious award to his collection: the 2024 VinFuture Grand Prize.

The US$3-million prize, awarded by the not-for-profit VinFuture Foundation in Vietnam, recognizes seminal scientific advancements that are improving the quality of human life and forging a more equitable and sustainable world.

Hinton, known as the “godfather of AI,” shares the prize with Yoshua Bengio, Jen-Hsun (Jensen) Huang, Yann LeCun and Fei-Fei Li. The five are honoured for their contributions to the development and adoption of deep learning, which is revolutionizing fields ranging from biomedical research and transportation to manufacturing, clean energy and agriculture.

“The University of Toronto couldn’t be more proud of University Professor Emeritus Geoff Hinton,” said Leah Cowen, ��ֱ��’s vice-president, research and innovation, and strategic initiatives. “When Geoff arrived at ��ֱ�� nearly 40 years ago, his research into neural networks – influenced by his ideas about how the brain learns – was considered an AI backwater, if it was considered at all.

“Fast-forward to today, and his seminal work is transforming our world in ways that we’ve only begun to grasp. This award is a testament to the power of curiosity-driven research – and the impact of investing in brilliant, curious researchers.”

The VinFuture Foundation noted that Hinton and Bengio – a professor at the Université de Montréal – were awarded the prize for their research on neural networks and deep learning algorithms. LeCun, the chief AI scientist for Facebook AI Research who was one of Hinton’s post-doctoral students at ��ֱ�� in the1980s, was recognized for helping develop convolutional neural networks for computer vision. Huang, the co-founder and CEO of NVIDIA, was recognized for his work on computational architectures for deep learning and accelerated computing, while Li, a professor at Stanford University, was celebrated for contributions to computer vision and large-scale image recognition.

In a video message, Hinton, an adviser at ��ֱ��’s Schwartz Reisman Institute for Technology and Society who is also co-founder and chief scientific adviser at the Vector Institute for Artificial Intelligence in Toronto, said he was honoured to share the award with such an esteemed group of researchers – including his fellow A.M Turing Award-winners Bengio and LeCun.

“The three of us spent our whole lives developing the technology of neural networks,” Hinton said in remarks that noted the collective nature of the achievement.

“I’m very happy to see that the VinFuture Prize recognizes the contributions of Jensen Huang in developing the kind of compute and software required for artificial intelligence, and Fei-Fei Li in providing the big data that was needed to prove that it worked.”

Now in its fourth year, the VinFuture Prize was created with the goal of celebrating scientific and technological innovations that are aligned with the United Nations’ 17 Sustainable Development Goals, which include poverty alleviation, renewable energy, ending hunger and improving health.

Friday’s award ceremony was attended by Vietnam’s Prime Minister Pham Minh Chinh and distinguished leaders, scientists and diplomats from around the world. It was broadcast live on Vietnamese television and streamed online.

“It’s terrific to see this recognition of Geoff’s extraordinary work and its potential to help address some of the world’s greatest challenges,” said Cowen. “Researchers around the globe – including a number of his former students – are using AI to help solve some of the most pressing challenges of our time in areas such as health care, sustainability and climate change.”

The prize comes as Hinton prepares to officially accept his Nobel Prize in Physics in Sweden on Dec. 10. He shared the Nobel with John J. Hopfield of Princeton University for foundational discoveries and inventions that enable machine learning with artificial neural networks.

Hinton, who joined ��ֱ�� in 1987 after working in universities in the U.K. and U.S., has said that he plans to leverage his growing fame to spread awareness of the dangers of unchecked AI development – a warning he first shared after leaving a research position at Google in early 2023.

The 2024 co-winner of the Nobel Prize in Physics - known to many as the "godfather of AI" - was honoured at an event attended by a who's who of the Toronto research community

There were standing ovations, peals of laughter and even a few tears as the University of Toronto welcomed Geoffrey Hinton back to campus after he won the 2024 Nobel Prize in Physics.

A University Professor Emeritus of computer science, Hinton traded the “cheap hotel room in California,” where he received the life-changing news, for an emotional reception in the Schwartz Reisman Innovation Campus’s airy event hall.

The Oct. 10 event drew ��ֱ�� leaders, supporters, dignitaries and other luminaries. They included Deputy Prime Minister Chrystia Freeland, University Professor Emeritus John Polanyi, who won the Nobel Prize in Chemistry in 1986, and Massey College Principal James Orbinski, who accepted the Nobel Peace Prize on behalf of Doctors Without Borders in 1999.

Several of Hinton’s many collaborators and proteges also attended the event – not to mention students who were simply eager to catch a glimpse of the “godfather of AI.”

Though sleep deprived, Hinton regaled the audience with fond recollections of his early years as an AI researcher, snapshots of his trademark dry humour and warm expressions of gratitude for mentors, collaborators and, of course, his many students.

“I’ve been blessed to have brilliant graduate students and post-docs,” Hinton said.

“I had a principle when selecting graduate students: ‘If they’re not smarter than me, what’s the point?’ And I’ve had quite a number of graduate students who were smarter than me.

“They did things I wouldn’t have been able to do, so I’d like to thank them.”

He said two figures in particular played a huge role in the work that led to his Nobel Prize, which he shared with Princeton University’s John J. Hopfield. The first was Terry Sejnowsky, a computational neuroscientist and former student of Hopfield’s, who worked with Hinton on Boltzmann machines – a period Hinton described as “the most happy research time of my life.”

He also praised the contributions of the late David Rumelhart, a psychologist at Stanford University, who worked with him to develop backpropagation algorithms, a key breakthrough.

“[He] should have won the Nobel Prize,” Hinton said. “But unfortunately, Dave got a horrible brain disease and he died quite young.” (The Nobel organization doesn’t award the honour posthumously).

Chris Maddison joined Hinton’s research group as an undergraduate and was one of the last students he supervised. Now an assistant professor in ��ֱ��’s departments of computer science and statistical sciences in the Faculty of Arts & Science, Maddison lauded Hinton as “a steadfast mentor and supporter who saw strength in me that I didn’t see” and said one of his greatest attributes was his sheer enthusiasm.

“No matter what’s going on, you can find him in the lab on Sundays at 8 p.m. playing with his MATLAB scripts like a child playing with Legos,” Maddison said. “He never lost that child-like sense of wonder that buoyed him and the group.”

��ֱ�� President Meric Gertler, who was in Indonesia on university business when the prize was announced, hailed Hinton in a video message as “one of the great minds of the 21st century” and someone who “literally created new ways of thinking about thinking and learning.”

He noted that Hinton’s AI leadership extends to the pressing question of responsible and safe development of the technology.

“With his Nobel win, he’s now perfectly positioned to amplify this concern on a world stage.” President Gertler said.

Leah Cowen, ��ֱ��’s vice-president, research and innovation, and strategic initiatives, reminded the accomplished audience that Hinton’s historic achievement – both the Nobel Prize and the AI revolution he helped spark – was the result of years toiling in an “unpromising backwater” of AI research.

“It is tempting to think that it happened almost overnight, but it didn’t,” Cowen said.

Hinton took time to reflect on periods of personal struggle and tragedy – and thank those who helped him in his hour of need.

When his wife had an incurable form of cancer, he recalled how ��ֱ�� President Emeritus David Naylor, a physician, medical researcher and former dean of the Temerty Faculty of Medicine, carried out research on a possible alternative treatment that was being explored – incorporating input from top medical experts – and presented him with a report of his findings.

“He’s a tremendous human being,” Hinton said of Naylor, who was in the audience.

Hinton also recalled how, when his first wife became ill in 1993 – also with cancer – his post-doctoral trainee Peter Dayan, now a director at the Max Planck Institute for Biological Cybernetics, stepped in to advise Hinton’s graduate students, giving him time to care for his ailing spouse.

“At times like this, you remember the people who helped you most when things were very difficult,” Hinton said.

He later pointed out that Dayan went on to supervise one of this year’s winners of the Nobel Prize in Chemistry, Demis Hassabis, joking that this made Dayan “the meat in a Nobel sandwich.”

For Minister Freeland, Hinton’s award showcased the value of ideas and of fundamental research. She said Hinton’s Nobel Prize sent waves of pride across Canada, which she said was “lucky as a country” that Hinton arrived on its shores back in 1987.

“Geoff shows that you can be a really brilliant intellectual and also a really great human being who cares about his community and his country,” Freeland said. “I am constantly struck by how Geoff thinks about the bigger implications of his ideas and how Geoff thinks about really wanting to make Canada and the world a better place.”

Brendan Frey, professor in the Faculty of Applied Science & Engineering and CEO of AI-powered therapeutics startup Deep Genomics, said he was one of many who earned his PhD under Hinton’s supervision.

“I think of Geoff as the father of a community that includes myself, other graduate students and all the people who didn’t believe but then came to believe – and he inspired all of us,” said Frey, who shared a hug with his former supervisor following the event.

“I’m really happy for him.”

"We should be building AI systems that promote human flourishing – that allow human beings to live with dignity and purpose, and to be valued contributors to society”

What does safe artificial intelligence look like? Could AI go rogue and pose an existential threat to humanity? How have media portrayals of AI influenced people’s perceptions of the technology’s benefits and risks?

These were among the pressing questions tackled by four experts at the University of Toronto and its partner institutions – in disciplines ranging from computer science to philosophy – during a recent panel discussion on AI safety.

Sheila McIlraith, professor in ��ֱ��’s department of computer science at the Faculty of Arts & Science and Canada CIFAR AI Chair at the Vector Institute, said the notion of AI safety evokes different things to different people.

“Computer scientists often think about safety critical systems – the types of systems that we’ve built to send astronauts to the moon or control our nuclear power plants – but AI safety is actually quite different,” said McIlraith, an associate director at the ��ֱ��’s Schwartz Reisman Institute for Technology and Society (SRI).

“For me personally, I have a higher bar, and I really think we should be building AI systems that promote human flourishing – that allow human beings to live with dignity and purpose, and to be valued contributors to society.”

The event, hosted by SRI in partnership with the Vector Institute, the Institute for the History & Philosophy of Science & Technology, the Centre for Ethics and Victoria College, invited McIlraith and her fellow panelists to discuss how AI technologies can be aligned with human values in an increasingly automated world.

They also discussed how risks surrounding the technology can be mitigated in different sectors.

Moderator, Karina Vold, assistant professor in the Institute for the History & Philosophy of Science & Technology in the Faculty of Arts & Science, noted that because AI systems operate “in a world filled with uncertainty and volatility, the challenge of building safe and reliable AI is not easy and mitigation strategies vary widely.”

She proceeded to ask the panel to share their thoughts on the portrayal of AI in popular culture.

“The media devotes more attention to different aspects of AI – the social, philosophical, maybe even psychological,” said Sedef Kocak, director of AI professional development at the Vector Institute.

“These narratives are important to help show the potential fears, as well as the positive potential of the technology.”

The discussion touched on several topics related to AI safety (photo by Duane Cole)

Roger Grosse, associate professor in ��ֱ��’s department of computer science in the Faculty of Arts & Science and a founding member of the Vector Institute, said that safety concerns around AI are not merely rooted in science and pop culture, but also in philosophy.

“Many people think that the public’s concerns regarding AI risks come from sci-fi, but I think the early reasoning regarding AI risks actually has its roots in philosophy,” said Grosse, who also holds Schwartz Reisman Chair in Technology and Society.

“If we’re trying to reason about AI systems that don’t yet exist, we don’t have the empirical information, and don’t yet know what their design would be, what we can do is come up with various thought experiments. For example, what if we designed an AI that has some specific role, and all of the actions that it takes are in service of the role?

“For the last decade, a lot of the reasons for being concerned about the long-term existential risks really came from this careful philosophical reasoning.”

The discussion also touched on the dangers of AI models misaligning themselves, how to guard against bias in the training of large language models, and how to ensure that AI models with potentially catastrophic capabilities are safeguarded.

“This [safeguarding] is an area where new research ideas and principles will be required to make the case,” said Grosse. “Developers saying, ‘Trust us’ is not sufficient. It’s not a good foundation for policy.”

Despite addressing topics surrounding potential harms and risks of AI, the panelists also shared their optimism about how AI can be wielded for the greater good – with Grosse noting AI offers the promise of making knowledge more widely accessible, and Kocak focusing on the myriad benefits for industries.

Roger Grosse and David Duvenaud named Schwartz Reisman Chairs in Technology and Society, while David Lie becomes the institute’s new director

A leading expert in cybersecurity and two renowned AI safety researchers are set to take on leading roles at the University of Toronto’s Schwartz Reisman Institute for Technology and Society.

David Lie, who is known for his seminal work that led to modern trusted execution processor architectures, has been named the new director of the Schwartz Reisman Institute (SRI), which aims to explore and address the ethical and societal implications of artificial intelligence and other emerging technologies.

His four-year appointment, which takes effect July 1, coincides with two renowned experts in AI safety – Roger Grosse and David Duvenaud – being named Schwartz Reisman Chairs in Technology and Society for five-year terms.

“I think one of the top priorities is ensuring that SRI and ��ֱ�� are the primary places in Canada – and perhaps in the world – for AI safety discussion and research,” says Lie, a professor in the Faculty of Applied Science & Engineering’s Edward S. Rogers Sr. department of electrical and computer engineering.

“My vision is to make us one of the leaders. Canada has already contributed greatly to machine learning and AI through the contributions of previous scholars like [University Professor Emeritus] Geoffrey Hinton, and I think we have a very strong role to play in this important technology going forward.”

The appointments come as inaugural director and chair Gillian Hadfield prepares to conclude her term as chair this month (she stepped down as director at the end of last year). The institute, created following a historic gift in 2019 from business leaders Gerald Schwartz and Heather Reisman, brings together experts from disciplines across ��ֱ��’s three campuses to steer AI development to prioritize safety and human welfare.

“We are thrilled to welcome David Lie, Roger Grosse and David Duvenaud to their new roles at the Schwartz Reisman Institute,” says Melanie Woodin, dean of the Faculty of Arts & Science. “Their expertise and leadership will be instrumental in fostering the interdisciplinary collaboration needed for the University of Toronto to remain at the forefront of technological innovation that benefits humanity.”

Lie, who has served as a research lead at SRI and holds cross-appointments in the department of computer science and the Faculty of Law, says his decades of research on making computer systems more secure and trustworthy – including contributions to computer architecture, formal verification, techniques using operating systems and networking – have equipped him to tackle the complex issues posed by AI, which will require researchers to anticipate and adapt to the unexpected.

“As AI become more powerful, they may do things – or are already doing things – that we didn’t anticipate or expect,” says Lie. “Bringing cybersecurity skills, thinking and tools into the AI safety discussion will be absolutely critical to solving the problem.”

Lie emphasizes that interdisciplinary collaboration is key to addressing potential AI disruption, noting that it has been pivotal in his own research and other roles.

His current research focuses on securing mobile platforms, cloud computing security and bridging the divide between technology and policy. He is also an associate director at the Data Sciences Institute, a ��ֱ�� institutional strategic initiative, a faculty affiliate at the Vector Institute for Artificial Intelligence and a senior fellow at Massey College.

“It’s really one of the things that I love about a place like ��ֱ��, because it's big and you have experts in every imaginable field to collaborate with,” he says. “I feel very strongly that we can always accomplish way more together than we can individually. That's true for people, but that's also true for disciplines.”

As incoming Schwartz Reisman Chairs in Technology and Society, Grosse and Duvenaud have vital roles to play in driving SRI’s research agenda and sharing its findings with the world, says Lie.

“One of the main ways universities contribute to society is through research, but we also contribute through discourse; we contribute by translating knowledge and providing that to policymakers, decision-makers and stakeholders,” he says. “I see SRI playing an important part in these roles.”

Both Grosse and Duvenaud are associate professors of computer science in the Faculty of Arts & Science, faculty affiliates at SRI, founding members of the Vector Institute and Canada CIFAR AI chairs – and both are working at San Francisco-based Anthropic, a research company focused on AI safety and alignment.

Grosse, whose research applies our understanding of deep learning to the safety and alignment of AI systems, says academia has an essential role to play in guiding AI development by looking beyond short-term incentives to ask how these technologies can be safely and ethically integrated for the long-term benefit of humanity.

“I'm very excited to be able to understand and mitigate catastrophic risks from AI, to be part of an interdisciplinary community that's especially well positioned to make progress in these issues, and I really appreciate the leadership that donors are showing and supporting this work,” he says.

“I think academia is great for being able to ask the more fundamental questions, to carry out maybe more forward-looking research that might not be directly on a company's critical path, but will contribute to safety efforts at many different organizations.”

Duvenaud’s research, meanwhile, focuses on probabilistic deep learning, artificial general intelligence governance and dangerous capabilities evaluation.

He envisions SRI as a “centre of gravity” where academics, industry members, government leaders and other stakeholders can engage with each other and shape the future of AI technologies.

“The idea is that by having this institute dedicated to this direction, we’ll be able to do things like host visitors and engage with academics from all sorts of disciplines –such as law, economics, and other parts of civil society – so that, ultimately, when policy discussions come up, we’ll be equipped and credible as people who can help governments navigate these decisions,” says Duvenaud, who is cross appointed to the department of statistical sciences.

Sheila McIlraith, an associate director and research lead at SRI, professor of computer science in the Faculty of Arts & Science, and a Canada CIFAR AI Chair at the Vector Institute, underlines the importance of rallying diverse disciplinary experts from across ��ֱ�� to address the opportunities and challenges that AI will wield in the coming years.

“AI is no longer the sole purview of computer scientists. It is reshaping the way we live, work, and interact with each other, and it will take experts from a broad range of disciplines to help ensure that AI is developed and deployed for the benefit of humanity, and that Canada adapts swiftly to protect our institutions," says McIlraith, who is an expert in AI safety research herself.

“Threats are already upon us; now is the time to act.”

Artificial intelligence presents new opportunities to strengthen democracy even as it threatens to cast a shadow over election integrity and further the spread of misinformation.

In the fifth episode of What Now? AI, University of Toronto hosts Beth Coleman and Rahul Krishnan are joined by experts Harper Reed and Peter Loewen, who is also from ��ֱ��, to explore the impact of AI on the political realm.

Listen to episode five on Apple, Spotify, SoundCloud, iHeartRadio and Amazon. Watch episode five on YouTube.

Loewen, director of ��ֱ��’s Munk School of Global Affairs & Public Policy and a professor in the department of political science in the Faculty of Arts & Science, explains how AI removes the human touch from politics, potentially making the public uneasy.

“We still don't like the fact that it might be a machine that we're talking to,” said Loewen, who is also the associate director of the Schwartz Reisman Institute for Technology and Society.

“But then if you layer on this dimension of not knowing if this is actually the campaign that’s doing it, I think that’s probably orders of magnitude worse because what it does is it takes us from the realm of kind of feeling uneasy about something into feeling like this thing is corrupted.”

Reed, meanwhile, spoke about his experience as the chief technology officer on former U.S. president Barack Obama’s re-election campaign in 2012.

“The technology we built was not about convincing someone at the time that Mitt Romney was a bad person or a good person,” said Reed during a conversation with Coleman about AI and democracy that was filmed live at the Schwartz Reisman Institute for Technology and Society’s annual conference Absolutely Interdisciplinary, a portion of which was used in the podcast episode.

“The tech was more about making sure you got to vote.”

When asked about the biggest threats to AI and democracy, Reed emphasized that he is less worried about the technology itself and more with ensuring it’s beneficial to societal use.

“I’m worried about who has access to it and how they are using it.”

Total enrolment in courses featuring Embedded Ethics Education Initiative modules exceeded 8,000 students this year

Computer science students at the University of Toronto are learning how to incorporate ethical considerations into the design and development of new technologies such as artificial intelligence with the help of a unique undergraduate initiative.

The Embedded Ethics Education Initiative (E3I) aims to provide students with the ability to critically assess the societal impacts of the technologies they will be designing and developing throughout their careers. That includes grappling with issues such as AI safety, data privacy and misinformation.

Program co-creator Sheila McIlraith, a professor in the department of computer science in the Faculty of Arts & Science and an associate director at the Schwartz Reisman Institute for Technology and Society (SRI), says E3I aims to help students “recognize the broader ramifications of the technology they’re developing on diverse stakeholders, and to avoid or mitigate any negative impact.”

First launched in 2020 as a two-year pilot program, the initiative is a collaborative venture between the department of computer science and SRI in association with the department of philosophy. It integrates ethics modules into select undergraduate computer science courses – and has reached thousands of ��ֱ�� students in this academic year alone.

Malaikah Hussain is one of the many ��ֱ�� students who has benefited from the initiative. As a first-year student enrolled in CSC111: Foundations of Computer Science II, she participated in an E3I module that explored how a data structure she learned about in class laid the foundation of a contact tracing system and raised ethical issues concerning data collection.

“The modules underlined how the software design choices we make extend beyond computing efficiency concerns to grave ethical concerns such as privacy,” says Hussain, who is now a third-year computer science specialist.

Hussain adds that the modules propelled her interest in ethics and computing, leading her to pursue upper year courses on the topic. During a subsequent internship, she organized an event about the ethics surrounding e-waste disposal and the company’s technology life cycle.

“The E3I modules have been crucial in shaping my approach to my studies and work, emphasizing the importance of ethics in every aspect of computing,” she says.

The program, which initially reached 400 students, has seen significant growth over the last four years. This academic year alone, total enrolment in computer science courses with E3I programming has exceeded 8,000 students. Another 1,500 students participated in E3I programming in courses outside computer science.

In recognition of the program’s impact on the undergraduate student learning experience, McIlraith and her colleagues – Diane Horton and David Liu, a professor and associate professor, teaching stream, respectively, in the department of computer science, and Steven Coyne, an assistant professor who is jointly appointed to the departments of computer science and philosophy – were recently recognized with the 2024 Northrop Frye Award (Team), one of the prestigious ��ֱ�� ֱ�� Association Awards of Excellence.

Horton, who leads the initiative’s assessment efforts, points to the team’s recently published paper showing that after participating in modules in only one or two courses, students are inspired to learn more about ethics and are benefiting in the workplace.

“We have evidence that they are better able to identify ethical issues arising in their work, and that the modules help them navigate those issues,” she says.

Horton adds that the findings build on earlier assessment work showing that after experiencing modules in only one course, students became more interested in ethics and tech, and more confident in their ability to deal with ethical issues they might encounter.

The team says the initiative’s interdisciplinary nature is key to delivering both a curriculum and experience with an authentic voice, giving instructors and students the vocabulary and depth of knowledge to engage on issues such as privacy, well-being and harm.

“As a philosopher and ethicist, I love teaching in a computer science department,” says Coyne. “My colleagues teach me about interesting ethical problems that they’ve found in their class material, and I get to reciprocate by finding distinctions and ideas that illuminate those problems. And we learn a lot from each other – intellectually and pedagogically – when we design a module for that class together.”

E3I is founded upon three key principles: teach students how – not what – to think; encourage ethics-informed design choices as a design principle; and make discussions safe, not personal.

“Engaging with students and making them feel safe, not proselytizing, inviting the students to participate is especially important,” says Liu.

The modules support this type of learning environment by using stakeholders with fictional character profiles that include names, pictures and a backstory.

“Fictional stakeholders help add a layer of distance so students can think through the issues without having to say, ‘This is what I think,’” Horton says. “Stakeholders also increase their awareness of the different kinds of people who might be impacted.”

McIlraith adds that having students advocate for an opinion that is not necessarily their own encourages empathy, while Liu notes that many have a “real hunger” to learn about the ethical considerations of their work.

“An increasing number of students are thinking, ‘I want to be trained as a computer scientist and I want to use my skills after graduation,’ but also ‘I want to do something that I think will make a positive impact on the world,’” he says.

Together, the E3I team works with course instructors to develop educational modules that tightly pair ethical concepts with course-specific technical material. In an applied software design course, for example, students learn about accessible software and disability theory; in a theoretical algorithms course, they learn about algorithmic fairness and distributive justice; and in a game design course, they learn about addiction and consent.

Steve Engels, a computer science professor, teaching stream, says integrating an ethics module about addiction into his fourth-year capstone course on video game design felt like a natural extension of his lecture topic on ludology – in particular, the psychological techniques used to make games compelling – instead of something that felt artificially inserted into the course.

“Project-based courses can sometimes compel students to focus primarily on the final product of the course, but this module provided an opportunity to pause and reflect on what they were doing and why,” Engels says. “It forced them to confront their role in the important and current issue of gaming addiction, so they would be more aware of the ethical implications of their future work and thus be better equipped to handle it.”

By next year, each undergraduate computer science student will encounter E3I modules in at least one or two courses every year throughout their program. The team is also exploring the adoption of the E3I model in other STEM disciplines, from ecology to statistics. Beyond ��ֱ��, the team plans to share their expertise with other Canadian universities that are interested in developing a similar program.

“This initiative is having a huge impact,” McIlraith says. “You see it in the number of students we’re reaching and in our assessment results. But it’s more than that – we’re instigating a culture change.”

The creative industry is poised to be forever changed by artificial intelligence.

Writing tools like ChatGPT and image generators like Midjourney and DALL-E have exploded into the mainstream. Adobe built its own version of generative AI technology for its creative suites and OpenAI announced its text-to-video model, Sora.

What impact will these tools and models have on the creative process? How will they change the role of an artist?

In the fourth episode of What Now? AI, hosts Beth Coleman and Rahul Krishnan dive into these questions with AI researchers Sanja Fidler of the University of Toronto and Nick Frosst, who co-founded the startup Cohere.

Listen to episode four on  Apple, Spotify, SoundCloud, iHeartRadio and Amazon. Watch episode four on YouTube. 

Fidler, the vice president of AI research at NVIDIA and an associate professor of mathematical and computational sciences at ��ֱ�� Mississauga, says that while AI technology is still in its early stage, it has the potential to provide artists with more adaptability and creative control.

“When artists see these methods like text-to-x, text-to-image or text-to-video, I feel that they have pushback because now there is only text that allows you to control the content,” says Fidler, an affiliate faculty member at the Vector Institute, which she co-founded.

“I think artists do want to have this iterative creative control. They have some idea in their head, and they have all these tools that allowed them to go from that idea into the final product. We want to do the same thing with AI as well.”

Frosst, who sings in the band Good Kid, says he doesn’t use large language models to help him write songs – only to help analyze lyrics and themes.

“I’m not really looking to optimize my artistic expression,” says Frosst, who completed his undergraduate degree in computer science and cognitive science at ��ֱ��.

“I don’t really want to write a new Good Kid song and be less involved. I want to be more involved.”

Frosst believes AI will change the way art is created, but not to the point where people aren’t interested in the artists who are making it.

“We want to know who made it, and that’s mostly what’s enjoyable about it.”

While the news headlines about AI often focus on dangers and risks, the potential for life-saving innovation in fields such as health care is huge.

In the third episode of What Now? AI, co-hosts Beth Coleman and Rahul Krishnan of the University of Toronto are joined by experts Christine Allen and Andrew Pinto to discuss AI’s potential to advance drug development and dramatically improve primary care.

Listen to episode three on Apple, Spotify, SoundCloud, iHeartRadio and Amazon. Watch episode three on YouTube.

Allen, a professor in ��ֱ��’s Leslie Dan Faculty of Pharmacy and an expert in drug formulation and development, co-founded Intrepid Labs Inc. with Alán Aspuru-Guzik, a professor in the departments of chemistry and computer science in ��ֱ��’s Faculty of Arts & Science.

One of the first startups to emerge from the Acceleration Consortium at ��ֱ��, Intrepid Labs is accelerating pharmaceutical drug development through the integration of AI, automation and advanced computing.

“It’s this concept of using AI to explore the unexplored,” Allen says.

“What if that formulation could really transform the properties and performance of your drug is one of those unexplored formulations. That will then take that drug through clinical development smoothly and get it to patients faster, which is really the goal.”

Meanwhile, Pinto, a family physician at St. Michael’s Hospital and director of the Upstream Lab, Unity Health Toronto, focuses his research on addressing the social determinants of health by running clinical trials of interventions and using AI tools for surveillance of respiratory illness.

“When we started to do this work around AI in primary care, we wanted to be directed by primary care providers and patients,” says Pinto, an associate professor in the department of family and community medicine in ��ֱ��’s Temerty Faculty of Medicine and at the Dalla Lana School of Public Health.

Reducing health-care inequities is top of mind for Pinto. His lab focuses on implementing AI to prioritize community engagement and bridge socioeconomic gaps to mitigate biases.

“We’re using these tools to look at all of the patients in a population and then focus our attention on the people who need it most.”

As AI becomes more integrated into our lives, how do we make sure it aligns with our values while minimizing risks?

In the second episode of What Now? AI, hosts Beth Coleman and Rahul Krishnan are joined by University of Toronto experts Gillian Hadfield and Roger Grosse as they tackle critical questions surrounding AI safety, regulation and alignment.

Listen to episode two on Apple, Spotify, SoundCloud, iHeartRadio and Amazon. Watch episode two on YouTube.

Grosse, an associate professor of computer science in the Faculty of Arts & Science and a founding member of the Vector Institute, joined the technical staff on the alignment team at Anthropic, an AI safety and research company based in San Francisco, during a sabbatical last year.

He calls working on AI research and systems while investigating safety a “difficult needle to thread.”

“As you move up the ladder of different AI capabilities, new requirements start kicking in – in terms of keeping the models secure from bad actors and being able to make sure they won’t intentionally carry out harmful plans,” says Grosse, a faculty affiliate at the Schwartz Reisman Institute for Technology and Society.

Hadfield, a professor of law and strategic management in the Faculty of Law and the inaugural Schwartz Reisman Chair in Technology and Society, has proposed a national registry for large AI models. She thinks companies should disclose to governments what they’re building, the data being used and the AI model’s capabilities.

“This is a unique moment in human history,” says Hadfield, who holds a CIFAR AI Chair at the Vector Institute for AI and served as a senior policy adviser to OpenAI from 2018 to 2023. “I think this is the first time that you have such a powerful technology that is being developed almost exclusively within private technology companies, so the public and the academic sector don’t have full visibility into how the technology is working.”
