Paul Dietz says robotic paper creations are a creative – and more inclusive – way to get kids interested in STEM fields

Could a talking paper octopus be the key to igniting kids' curiosity about technology?

University of Toronto engineer Paul Dietz certainly thinks so. With the help of a menagerie of mechanically controlled puppets, he has a plan to help students learn to think creatively across a wide range of fields.

All it takes is some simple circuitry, a few arts and crafts supplies – and a lot of imagination.

A distinguished engineer in residence and director of fabrication in the Faculty of Arts and Science’s computer science department, Dietz is the whimsical mind behind the Animatronics Workshop. The program collaborates with schools to provide opportunities for children to create, design and build their own robotic shows.

Dietz has been partnering with schools where kids create their own animatronic stories – from staging pre-programmed puppet shows to hosting Q-and-As with Shakespeare – departing from the competition-based competitions typical of many youth robotics efforts.

Dietz’s program has been his passion project for a decade and a half, developed on the side while he worked day jobs engineering innovations for companies like Microsoft, Mitsubishi and Disney, as well as his own startups.

Now, at ��˾��ֱ��, Dietz is focusing on bringing accessible and affordable animatronics to classrooms across Canada. The goal, he says, is to teach kids to use technology as a tool for storytelling, dismantling what he sees as a false divide between the arts and sciences.

“One of the first participants in this program was a young girl who was really into writing creative stories and really loved science. And she saw these as two conflicting parts of her world,” says Dietz, who is also a faculty affiliate at the Schwartz Reisman Institute for Technology and Society.

“After what she did in animatronics, it suddenly dawned on her that you can do both. If you do engineering right, it is a creative art.”

Dietz had a similar realization as a teenager in the late 1970s, when a behind-the-scenes tour of Walt Disney Imagineering got him tinkering with an animatronic robot penguin.

This early fusion of technical skills and storytelling sensibilities set Dietz on a path that turned flights of imagination into real-world breakthroughs that shape our engagement with technology.

A prolific inventor and researcher, Dietz is best known for co-creating an early progenitor of the multi-touch display technology that’s ubiquitous in today’s smartphones and tablets. Other innovations include 'Pal Mickey,' an interactive plush toy that guided visitors through Disney theme parks, and parallel reality displays that allow multiple viewers to see individualized content on the same screen.

Dietz says his storied career debunks the common misconception – often reinforced in schools – that creativity is exclusive to artistic pursuits, while science is the domain of strict rationality, where there are prescribed methods of inquiry to arrive at a single correct answer.

As Dietz sees it, weaving a narrative and programming a robot are propelled by the same creative impulse – they just exercise different skills. He believes a well-rounded education should equip students with a diverse arsenal of tools to explore new ideas.

“If you’re an artist, you have to learn the mechanics of sculpting or painting or whatever your medium is,” he says. “We should be looking at engineering and technology as those tools, and the key is … learning how to use them creatively to achieve things that are actually positive for our society.”

The universal appeal of storytelling also serves to make technology accessible and exciting to kids of all ages and genders, Dietz adds.

Bridging the gender divide in STEM has been core to Dietz’s animatronics mission since its inception.

When his daughter was in middle school, Dietz took her to a robotics competition – but she was turned off by the contest, which seemed pointless to her. However, when the two of them worked together on an animatronic raccoon, he saw her passion for creating ignite.

“This light bulb went off in my head: Maybe the problem isn’t that we’re doing tech,” says Dietz. “Maybe kids like my daughter need to see some application that makes sense to them – like telling a story.”

Over the years, Dietz has partnered with several schools to set up animatronics workshops that attracted an even number of boys and girls and ensured every kid participated in all aspects of the projects – from storytelling and character design to robot building and programming.

But as his career took him across the U.S., Dietz found it difficult to sustain and replicate the success of the programs because of the prohibitive costs of full-scale animatronic robots and the significant technical expertise required from teachers.

At ��˾��ֱ��, Dietz is working to bring animatronics to schools of all resources, allowing students to develop creative and computer science skills by harnessing the endless storytelling possibilities of paper.

At the Dr. Eric Jackman Institute of Child Study (JICS) at ��˾��ֱ��’s Ontario Institute for Studies in Education, students from kindergarten through Grade 6 have put Dietz’s paper animatronics kits to the test, bringing characters to life with kinetic, vocal creations.

The laboratory school has hosted a series of pilot projects where kids fashioned characters out of construction paper, recorded voices and wired motorized movements to animate creations ranging from a chomping, sharp-toothed maw to a bouncing kitten.

Nick Song, a special education and technology teacher at JICS, says he sees enormous educational potential for paper animatronics to engage students in hands-on, interactive learning that simultaneously develops technology skills and fosters creative expression.

“The kids love doing things with technology because it gives them a really cool feedback loop where they can try something and see it work immediately,” says Song. “All of this is very motivating for kids, seeing something pick up their voice and start moving, and you almost feel like it’s coming to life.”

Building on the pilots at JICS, Dietz is aiming to scale up the program to schools across the country in hopes of nurturing the next generation of out-of-the-box innovators.

“It’s very different from the technical work that I’ve generally done … but it feels very right,” says Dietz. “I think we’re doing something important for Canada.”

The new tools could help robotic systems of autonomous vehicles better track the position and motion of vehicles, pedestrians and cyclists

Researchers at the University of Toronto Institute for Aerospace Studies (UTIAS) have introduced a pair of high-tech tools that could improve the safety and reliability of autonomous vehicles by enhancing the reasoning ability of their robotic systems.

The innovations address multi-object tracking, a process used by robotic systems to track the position and motion of objects – including vehicles, pedestrians and cyclists – to plan the path of self-driving cars in densely populated areas.

Tracking information is collected from computer vision sensors (2D camera images and 3D LIDAR scans) and filtered at each time stamp, 10 times a second, to predict the future movement of moving objects.

“Once processed, it allows the robot to develop some reasoning about its environment. For example, there is a human crossing the street at the intersection, or a cyclist changing lanes up ahead,” says Sandro Papais, a PhD student in UTIAS in the Faculty of Applied Science & Engineering. "At each time stamp, the robot’s software tries to link the current detections with objects it saw in the past, but it can only go back so far in time.”

In a new paper presented at the 2024 International Conference on Robotics and Automation in Yokohama, Japan, Papais and co-authors Robert Ren, a third-year engineering science student, and Professor Steven Waslander, director of UTIAS’s Toronto Robotics and AI Laboratory, introduce Sliding Window Tracker (SWTrack) – a graph-based optimization method that uses additional temporal information to prevent missed objects.

The tool is designed to improve the performance of tracking methods, particularly when objects are occluded from the robot’s point of view.

“SWTrack widens how far into the past a robot considers when planning,” says Papais. “So instead of being limited by what it just saw one frame ago and what is happening now, it can look over the past five seconds and then try to reason through all the different things it has seen.” 

The team tested, trained and validated their algorithm on field data obtained through nuScenes, a public, large-scale dataset for autonomous driving vehicles that have operated on roads in cities around the world. The data includes human annotations that the team used to benchmark the performance of SWTrack.

They found that each time they extended the temporal window, to a maximum of five seconds, the tracking performance got better. But past five seconds, the algorithm’s performance was slowed by computation time.

“Most tracking algorithms would have a tough time reasoning over some of these temporal gaps. But in our case, we were able to validate that we can track over these longer periods of time and maintain more consistent tracking for dynamic objects around us,” says Papais.

Papais says he’s looking forward to building on the idea of improving robot memory and extending it to other areas of robotics infrastructure. “This is just the beginning,” he says. “We’re working on the tracking problem, but also other robot problems, where we can incorporate more temporal information to enhance perception and robotic reasoning.”

Another paper, co-authored by master’s student Chang Won (John) Lee and Waslander, introduces UncertaintyTrack, a collection of extensions for 2D tracking-by-detection methods that leverages probabilistic object detection.

“Probabilistic object detection quantifies the uncertainty estimates of object detection,” explains Lee. “The key thing here is that for safety-critical tasks, you want to be able to know when the predicted detections are likely to cause errors in downstream tasks such as multi-object tracking. These errors can occur because of low-lighting conditions or heavy object occlusion.

“Uncertainty estimates give us an idea of when the model is in doubt, that is, when it is highly likely to give errors in predictions. But there’s this gap because probabilistic object detectors aren’t currently used in multi-tracking object tracking.” 

Lee worked on the paper as part of his undergraduate thesis in engineering science. Now a master’s student in Waslander’s lab, he is researching visual anomaly detection for the Canadarm3, Canada’s contribution to the U.S.-led Gateway lunar outpost. “In my current research, we are aiming to come up with a deep-learning-based method that detects objects floating in space that pose a potential risk to the robotic arm,” Lee says.

Waslander says the advancements outlined in the two papers build on work that his lab has been focusing on for a number of years.

“[The Toronto Robotics and AI Laboratory] has been working on assessing perception uncertainty and expanding temporal reasoning for robotics for multiple years now, as they are the key roadblocks to deploying robots in the open world more broadly,” Waslander says.

“We desperately need AI methods that can understand the persistence of objects over time, and ones that are aware of their own limitations and will stop and reason when something new or unexpected appears in their path. This is what our research aims to do.”

The Self-Driving Laboratory for Human Organ Mimicry is one of six self-driving labs launched by the Acceleration Consortium to drive research across a range of fields

The University of Toronto is home to a new “self-driving lab” that will allow researchers to better understand health and disease – and to more rapidly test the efficacy and toxicity of new drugs and materials.

Based at the Donnelly Centre for Cellular and Biomolecular Research, the Self-Driving Laboratory for Human Organ Mimicry is the latest self-driving lab to spring from a historic $200-million grant from the Canada First Research Excellence Fund to the Acceleration Consortium – a global effort to speed the discovery of materials and molecules that is one of several ��˾��ֱ�� institutional strategic initiatives.

The new lab will be led by Milica Radisic, Canada Research Chair in Organ-on-a-Chip Engineering and professor of biomedical engineering in the Faculty of Applied Science & Engineering, and Vuk Stambolic, senior scientist at the Princess Margaret Cancer Centre, University Health Network, and a professor of medical biophysics in the Temerty Faculty of Medicine.

“The lab will innovate new complex cellular models of human tissues, such as from the heart, liver, kidney and brain, through stem-cell-derived organoids and organ-on-a-chip technologies,” said Radisic. “In partnership with the Princess Margaret Cancer Centre, the lab will also enable automation of patient-derived tumour organoid cultures to accelerate the discovery of new cancer treatments.”

The Self-Driving Laboratory for Human Organ Mimicry is one of six self-driving labs launched by the Acceleration Consortium at ��˾��ֱ�� to drive research across a range of fields, including materials, drug formulation, drug discovery and sustainable energy.

How does a self-driving lab work? Once set up, it runs with robots and artificial intelligence performing as much as 90 per cent of the work. That, in turn, speeds up the process of discovery by freeing researchers from the tedious process of trial and error so they can focus on higher-level analysis.

“The Self-Driving Lab for Human Organ Mimicry will enable other self-driving labs to develop new materials and drugs by rapidly determining their efficacy, as well as their potential toxic effects and other impacts on human tissues,” said Stambolic. “While animal testing is typically the go-to method to assess the safety of new molecules made for humans, this lab will replace trials involving animals with organoids and organs-on-chips. This will allow us to advance to human clinical trials much more quickly.”

“The goal of our self-driving labs is to use AI to move the discovery process forward at the necessary pace to tackle global issues,” said Alán Aspuru-Guzik, director of the Acceleration Consortium and professor of chemistry and computer science in the Faculty of Arts & Science. “The Human Organ Mimicry SDL, as well as other self-driving labs launched through the Acceleration Consortium, will establish ��˾��ֱ�� and our extended research community as a global leader in AI for science.”

Donnelly Centre Director Stephane Angers says the centre is an ideal environment for the new lab, citing the the international hub for cross-disciplinary health and medical research’s reputation as a hotspot for technological innovation – one that offers resources to the wider research community.

“The Donnelly Centre is a thriving research community because it was founded on the principle of interdisciplinary collaboration,” said Angers, a professor of biochemistry and pharmaceutical sciences. “Our research strengths in computational biology, functional genomics and stem cell biology will catalyze the development and success of the Self-Driving Lab for Human Organ Mimicry.”

The launch of the new lab will also expand the Donnelly Centre’s team of experts with the hiring of five new staff who will work to make the self-driving lab fully automated. The lab is expected to be operational by the end of the year

“The Donnelly Centre is one of the foremost research institutes in the world, with outstanding strength in genomics, model organisms, organoids, computational biology and many other areas,” said Justin Nodwell, vice-dean of research and health science education at the Temerty Faculty of Medicine.

“I’m delighted to hear about the addition of the Acceleration Consortium’s artificial intelligence-powered self-driving lab to the centre’s existing technical base. It will facilitate new lines of research by some of the best minds in the country.”

Hospital for Sick Children

Researchers at The Hospital for Sick Children (SickKids) and the University of Toronto Robotics Institute – an institutional strategic initiative – have teamed up to develop a new treatment option for patients diagnosed with glioblastoma (GBM).

Glioblastoma is the most common and aggressive form of brain cancer – the average life expectancy after a diagnosis is around 15 months.

Yu Sun, a professor in ��˾��ֱ��'s department of mechanical and industrial engineering in the Faculty of Applied Science and Engineering, and Xi Huang, a senior scientist at SickKids and an associate professor in the department of molecular genetics at the Temerty Faculty of Medicine, hope to change this dire statistic with the help of magnetically guided robotic nano-scalpels that can precisely target cancer cells and kill them. Findings from their research were recently shared in a new study published in Science Advances.

For decades, scientists have searched for ways to treat GBM, including conventional surgery, radiation, chemotherapy and targeted therapy. GBM cells quickly reproduce and invade nearby brain tissue and are notoriously difficult to eradicate by conventional surgery. These cells also develop resistance to chemotherapy or targeted therapy. As a result, patients usually relapse after undergoing currently available treatment protocols.

Sun and Huang believe that a mechanical nano-surgical approach targeting tumour cells could provide a new and effective treatment option.

Sun, who is joint appointed to the department of electrical and computer engineering as well as the department of computer science in the Faculty of Arts and Science and is director of the ��˾��ֱ�� Robotics Institute, has spent more than 20 years developing micro- and nano-robotic systems – including infertility treatment systems that can select sperm with high DNA integrity and inject it into a human egg. Huang, whose lab at SickKids specializes in developmental and stem-cell biology, investigates the physical properties and mechano-electrical-chemical signaling of brain cancer to develop new therapeutic strategies.

Together, they designed a precision control system that applies a rotating magnetic field to mobilize magnetic carbon nanotubes (mCNTs) filled with iron oxide particles and demonstrated that mCNT swarms could be activated inside a single cell to function as nano-scalpels.

They showed that mechanical stimulations provided by mobilized mCNTs inside GBM cells disrupt cancer cells’ internal structures leading to cell death. Importantly, the team demonstrated that the nano-surgical treatment reduced tumour size and extended the survival of mice bearing chemotherapy-resistant GBM.

With evidence from multiple preclinical models confirming the effectiveness of their approach, the researchers are next optimizing the material compositions of mCNTs, the control strategy and the treatment protocol.

Xian Wang – a former post-doctoral researcher in Huang’s lab and a recent graduate of Sun’s lab, where he began this work building magnetic nano-tweezers – is the first author of the paper. His work developing the nano-tweezers is what laid the research foundations for the nano-scalpels used in the current study. He recently joined Queen’s University as an assistant professor.

“In addition to physically disrupting cellular structures, mechanically mobilized mCNTs can also modulate specific biomedical pathways,” Wang says. “Based on this, we are now developing a combination therapy to tackle untreatable brain tumours.”

While there is still more research to conduct before human trials are initiated, this innovation in mechanical nano-surgery is giving patients, families and the medical community hope that new treatment options are on the horizon for an otherwise untreatable disease.

The research was supported by the Natural Sciences and Engineering Research Council of Canada and the Canadian Institutes of Health Research, among others.

A team of researchers at the University of Toronto has found a way to enhance the visual perception of robotic systems by coupling two different types of neural networks.

The innovation could help autonomous vehicles navigate busy streets or enable medical robots to work effectively in crowded hospital hallways.

“What tends to happen in our field is that when systems don’t perform as expected, the designers make the networks bigger – they add more parameters,” says Jonathan Kelly, an assistant professor at the University of Toronto Institute for Aerospace Studies in the Faculty of Applied Science & Engineering.

“What we’ve done instead is to carefully study how the pieces should fit together. Specifically, we investigated how two pieces of the motion estimation problem – accurate perception of depth and motion – can be joined together in a robust way.”

Researchers in Kelly’s Space and Terrestrial Autonomous Robotic Systems lab aim to build reliable systems that can help humans accomplish a variety of tasks. For example, they’ve designed an electric wheelchair that can automate some common tasks such as navigating through doorways.

More recently, they’ve focused on techniques that will help robots move out of the carefully controlled environments in which they are commonly used today and into the less predictable world humans are accustomed to navigating.

“Ultimately, we are looking to develop situational awareness for highly dynamic environments where people operate, whether it’s a crowded hospital hallway, a busy public square or a city street full of traffic and pedestrians,” says Kelly.

One challenging problem that robots must solve in all of these spaces is known to the robotics community as “structure from motion.” This is the process by which robots stitch together a set of images taken from a moving camera to build a 3D model of the environment they are in. The process is analogous to the way humans use their eyes to perceive the world around them.

In today’s robotic systems, structure from motion is typically achieved in two steps, each of which uses different information from a set of monocular images. One is depth perception, which tells the robot how far away the objects in its field of vision are. The other, known as egomotion, describes the 3D movement of the robot in relation to its environment.

“Any robot navigating within a space needs to know how far static and dynamic objects are in relation to itself, as well as how its motion changes a scene,” says Kelly. “For example, when a train moves along a track, a passenger looking out a window can observe that objects at a distance appear to move slowly, while objects nearby zoom past.”

The challenge is that in many current systems, depth estimation is separated from motion estimation – there is no explicit sharing of information between the two neural networks. Joining depth and motion estimation together ensures that each is consistent with the other.

“There are constraints on depth that are defined by motion, and there are constraints on motion that are defined by depth,” says Kelly. “If the system doesn’t couple these two neural network components, then the end result is an inaccurate estimate of where everything is in the world and where the robot is in relation.”

In a recent study, two of Kelly’s students – Brandon Wagstaff, a PhD candidate, and former PhD student Valentin Peretroukhin – investigated and improved on existing structure from motion methods.

Their new system makes the egomotion prediction a function of depth, increasing the system’s overall accuracy and reliability. They recently presented their work at the International Conference on Intelligent Robots and Systems (IROS) in Kyoto, Japan.

“Compared with existing learning-based methods, our new system was able to reduce the motion estimation error by approximately 50 per cent,” says Wagstaff.

“This improvement in motion estimation accuracy was demonstrated not only on data similar to that used to train the network, but also on significantly different forms of data, indicating that the proposed method was able to generalize across many different environments.”

Maintaining accuracy when operating within novel environments is challenging for neural networks. The team has since expanded their research beyond visual motion estimation to include inertial sensing – an extra sensor that is akin to the vestibular system in the human ear.

“We are now working on robotic applications that can mimic a human’s eyes and inner ears, which provides information about balance, motion and acceleration,” says Kelly.

“This will enable even more accurate motion estimation to handle situations like dramatic scene changes — such as an environment suddenly getting darker when a car enters a tunnel, or a camera failing when it looks directly into the sun.”

The potential applications for such new approaches are diverse, from improving the handling of self-driving vehicles to enabling aerial drones to fly safely through crowded environments to deliver goods or carry out environmental monitoring.

“We are not building machines that are left in cages,” says Kelly. “We want to design robust robots that can move safely around people and environments.”

Laura Maldonado beams as she describes her first day learning in ��˾��ֱ�� Mississauga’s Undergraduate Robotics Teaching Laboratory.

“It’s a really cool place,” she says, as she takes out her phone to show a video of one of the lab’s robots in action. “We actually play with these robots and get hands-on experience.”

The computer science specialist student was among the first group of undergraduates in the third-year Fundamentals of Robotics class to use the new lab, which officially opened its doors on Sept. 7.

Jessica Burgner-Kahrs, an associate professor in the department of mathematical and computational sciences who spearheaded the lab's creation, said the lab will be used primarily for computer science students who take robotics courses in their third and fourth years.

However, the lab will also be available to the broader ��˾��ֱ�� community – including graduate students in computer science, mechanical engineering and aerospace studies, says Burgner-Kahrs, who is cross-appointed to the department of computer science in the Faculty of Arts & Science and the department mechanical and industrial engineering in the Faculty of Applied Science & Engineering; and is founding director of the Continuum Robotics Laboratory.

She adds that it will also be a resource for the ��˾��ֱ�� Robotics Institute, where she is an associate director.

“I’m very thankful and very grateful that we now have this teaching lab for students, and you can tell by the students’ faces how happy they are,” she says. “I think it’s, by far, the most up-to-date teaching lab I’ve seen anywhere in Canada.”

Burgner-Kahrs, who teaches Maldonado’s "Fundamentals of Robotics" class, says the lab includes revolutionary types of robots called “cobots,” or “collaborative robots,” that have multiple movable joints and safety sensors so they can safely interact with humans. She says these kinds of robots have become more prevalent in recent years.

“They are more used for co-operative tasks, where humans and robots work alongside (each other),” explains Burgner-Kahrs, adding that they can be used to automate some tasks or perform more delicate tasks. “Robotics engineering is one of the fastest growing job markets, and all these new jobs will entail being familiar with these collaborative robots. It will put our students at an advantage in the job market.”

Sven Lilge, PhD student and teaching assistant for the robotics fundamentals course, says the lab offers a rare opportunity for undergraduate students to learn how robots work through practical experience. “What’s really unique is we have the ability for all of our students in our class, which is more than 60 students, to work hands-on with a robot,” he says. “It’s really a game-changer.”

Maldonado says the lab is also helping her apply learning from previous math courses – a subject that she admits isn’t her strongest.

“I used to think, ‘Why are we learning linear algebra? Why are we learning calculus? What’s the point of this?’” she says. “Now, I understand that I need to know how the robot moves. I need to understand three dimensions. I can physically see it with the robot.”

Maldonado adds that she feels lucky to be able to use a robotics lab during her undergraduate degree.

“The only way (students before me) really got to work on robotic stuff was if they maybe got research positions, or maybe they tried getting some internships – which was hard if you didn’t have physical experience,” she says. “Now, we get this hands-on experience. I think it’s a privilege.”

The University of Toronto welcomed South Korean President Yoon Suk-yeol to campus last week to discuss artificial intelligence (AI) – its rise, potential applications and opportunities for further collaboration between ��˾��ֱ�� and South Korean partners.

President Yoon hailed Toronto as an AI powerhouse, saying that Canada’s status as a world leader in AI and a centre of the global AI supply chain was the result of the country recognizing the potential economic and social impacts of the technology early on.

He also said the tenacity and persistence of researchers such as University Professor Emeritus Geoffrey Hinton, a pioneer of the AI field of deep learning, served as a “benchmark” for South Korean efforts to advance the technologies of the future, adding that he was delighted to visit ��˾��ֱ��, which he described as “one of the most prestigious universities in North America.”

��˾��ֱ�� President Meric Gertler, for his part, said he was “deeply honoured” to welcome President Yoon, who, he said, “has made it a priority to work closely with South Korea's allies and partners, advancing openness, human rights, democracy and the rule of law, with clear purpose and integrity.”

President Gertler noted that the South Korean delegation’s visit comes at a time when Toronto has emerged as the third-largest tech hub in North America, with the city’s AI and machine learning ecosystem at the heart of this growth.

“Together with the Vector Institute, the Canadian Institute for Advanced Research (CIFAR), MaRS and other partners – all within a walking distance of this room – we have created one of the world’s richest pools of talent,” President Gertler said.

He added that ��˾��ֱ��, its local partners and South Korean organizations stand to learn much from each other when it comes to AI research, development, innovation and education.

“Partnering with Korea’s leading universities, innovative firms and exceptionally talented researchers is an extraordinary opportunity for all parties to benefit as we deepen our collective commitment to excellence and to tackling the world’s most pressing challenges.”

President Yoon’s visit to ��˾��ֱ�� took place during the first day of his two-day visit to Canada, which included a meeting with Prime Minister Justin Trudeau in Ottawa the following day.

It also came less than two weeks after the government of Ontario concluded a trade mission to South Korea and Japan, led by Vic Fedeli, the province’s minister of economic development job creation and trade.

Fedeli, who attended the ��˾��ֱ�� event, said Toronto’s reputation as a global hub in AI was regularly impressed upon him during his time in South Korea.

“At every single stop that we made, we heard people talk about Canada, AI, ��˾��ֱ��, the Vector Institute – they see Canada as a real leader in AI and they’re very eager to learn,” Fedeli said.

He noted there was a strong desire in South Korea to see more Korean students come to Canada to further their education in STEM fields, including in AI. “They want a bigger influx of Korean students – and we told them, ‘The door’s open,’ because we really believe this is going to help society. We’ve seen some examples of what AI has done and we’re very eager to continue to see the development of AI.”

Fedeli added that he hoped the high-level meeting would further strengthen the economic relationship between Ontario and South Korea, helping to spark AI advances that give both Ontarian and Korean companies a competitive edge on the global stage.

Held at Simcoe Hall, the meeting included a roundtable discussion titled “AI for the Better Future of Humanity,” that featured AI leaders and luminaries, including Hinton and Lee Jong-ho, the Republic of Korea’s Minister of Science and ICT (information and communication technology).

The talk, moderated by Leah Cowen (pictured below), ��˾��ֱ��’s vice-president, research and innovation, and strategic initiatives, also included contributions from Garth Gibson, president and CEO of the Vector Institute for Artificial Intelligence; Elissa Strome, executive director of Pan-Canadian AI Strategy at CIFAR; and Professor Lisa Austin, chair in law and technology at ��˾��ֱ��’s Faculty of Law and associate director at the Schwartz Reisman Institute for Technology and Society.

Attendees watched demonstrations by ��˾��ֱ�� professors and graduate students from the ��˾��ֱ�� Robotics Institute, as well as presentations by South Korean companies, including Samsung and LG – both of which have expanded their presence and connections with Toronto and ��˾��ֱ�� in recent years – and was also used to announce a new ��˾��ֱ�� exchange program with the South Korean government’s Institute for Information & communication Technology Planning & evaluation (IITP).

On the subject of AI, Hinton said he believes the deep learning revolution is just getting underway and that he expects tremendous growth in the years ahead.

“We now know that if you take a neural net and you just make it bigger and give it more data and more computing power, it’ll work better. So even with no new scientific insights, things are going to improve,” Hinton said during the roundtable discussion. “But we also know there are tens of thousands of brilliant young minds now thinking about how to make these networks better, so there will be many new scientific insights.”

In the long-term, Hinton (pictured at the lecturn above) said he envisions a revolution in AI hardware led by advancements in “neuromorphic hardware” – computers and hardware that model artificial neural networks.

“I think Korea may have a big role to play in this,” Hinton said, noting one of the world’s leading experts in this area is Sebastian Seung, Samsung’s president and head of research – who attended the Simcoe Hall event.

When asked to share his thoughts on how Canada achieved its leadership position in AI, Hinton cited three foundational factors: a tolerant, liberal society that encourages leading researchers to settle here; the federal government’s funding for curiosity-driven basic research; and CIFAR’s funding, in 2004, of the Neural Computation and Adaptive Perception program, which is credited with kickstarting the revolution in deep learning.

Following the discussion, event attendees, including ��˾��ֱ�� students, watched presentations on avenues for AI research and collaboration by representatives of five South Korean companies: LG, Samsung, Naver, KT (formerly Korea Telecom) and SK Telecom.

Alex Mihailidis, ��˾��ֱ��’s associate vice-president, international partnerships, then announced that ��˾��ֱ�� had signed a memorandum of understanding with IITP, based in Seoul, to launch a bi-national education program in AI.

“We expect that in the fall of 2023, we will be accepting 30 students from Korea who will be going through a custom-made program around AI and its applications,” Mihailidis said. “This is a groundbreaking program that we expect will not only flourish here in Toronto but will grow – hopefully across our two great countries and around the world.”

Earlier, Mihailidis and President Gertler led President Yoon and Fedeli through four demonstrations showcasing some of the cutting-edge technologies being developed by ��˾��ֱ�� professors and their graduate students.

The technologies included: a wearable robotic exoskeleton for walking assistance and rehab demonstrated by Mihailidis and post-doctoral researcher Brokoslaw Laschowski; a sensory soft robotic hand for human-robot interaction demonstrated by Professor Xinyu Liu of the department of mechanical and industrial engineering in the Faculty of Applied Science & Engineering, graduate student Zhanfeng Zhou and post-doctoral researcher Peng Pan; a multimodal perception system for autonomous vehicles showcased by Jiachen (Jason) Zhou, a graduate student in robotics and aerospace engineering; and a nanorobot for precision manipulation under electron microscope that was demonstrated by Yu Sun, professor in the department of mechanical and industrial engineering and director of the ��˾��ֱ�� Robotics Institute.
