Engineering and one of the team’s academic advisers.&nbsp;&nbsp;&nbsp;</p> <p>“The team did another excellent job this year.â€&nbsp;&nbsp;</p> <p>The team approached the competition by going back to first principles to ensure they had a reliable and robust system, says&nbsp;<strong>Kelvin Cui</strong>, a 91³Ô¹Ï Engineering alumnus and&nbsp;the team’s principal.&nbsp;&nbsp;</p> <p>He joined aUToronto last fall after five years with the 91³Ô¹Ï Formula Racing team, where he founded the “driverless†division.&nbsp;&nbsp;&nbsp;</p> <p>“We looked at what was going to get us the most points at competition and made sure that we were not overbuilding our system and adding too much complexity,†he says.&nbsp;&nbsp;</p> <p>This meant pushing for additional testing time at UTIAS and achieving more than 900 kilometres of system testing prior to the competition.&nbsp;&nbsp;&nbsp;</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2024-08/AUTODRIVE_24_5334-crop.jpg?itok=xSJviMQl" width="750" height="500" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>The team placed first out of 10 teams from institutions across the United States and Canada (photo courtesy of aUToronto)</em></figcaption> </figure> <p>A partnership with the AutoDrive team from Queen’s University was instrumental to aUToronto’s preparation. The aUToronto team drove Artemis, their autonomous vehicle, to Kingston, Ont. to assess the system at Queen’s testing facility, which features intersections and electronic streetlights.&nbsp;&nbsp;</p> <p>“We added radar to our vehicle as a new sensor, so we needed to be aware of all the sensor failure modes,†says third-year Engineering Science student <strong>Robert Ren</strong>.&nbsp;&nbsp;</p> <p>“A lot of our testing time went into making sure that including radar didn’t break anything else in our system, and that it could handle any sensor failure cases.â€&nbsp;&nbsp;</p> <p>Including radar sensors in the vehicle’s perception system&nbsp;allowed it to measure the motion of objects directly, which is not possible with light detection and ranging (LiDAR) sensors. &nbsp;&nbsp;</p> <p>“Radar can help with adverse weather object detections,†adds Ren.&nbsp;“So, if the vehicle is operating under heavy rain or fog, the LiDAR is going to be limited, but the radio waves from radar can help the vehicle see what objects are in front and what objects are moving. This enables it to make good decisions when driving in uncertain scenarios.â€â€¯&nbsp;&nbsp;</p> <blockquote class="instagram-media" data-instgrm-captioned data-instgrm-permalink="https://www.instagram.com/p/C9ycZUeNM64/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14" style=" background:#FFF;

Then we screamed and cheered, and we could hear cheering from inside the car.â€&nbsp;&nbsp;</p> <p>“Our success is entirely a team effort,†adds Cui. “It was not smooth sailing before the competition. The only reason we won is because everybody put in so much effort to test our vehicle every day.</p> <p>“That’s how we were able to get this reliable system across the line.â€â€¯&nbsp;&nbsp;</p> <div> <div class="field field--name-field-media-oembed-video field--type-string field--label-hidden field__item"><iframe src="/media/oembed?url=https%3A//youtu.be/gG7DG-t2aiQ%3Fsi%3DkYGqZF0-x-6a4MBn&amp;max_width=0&amp;max_height=0&amp;hash=6whKFK-X5NSAGZdfMqSydpcgBMCmEPw2x-2wTgtl2jw" width="200" height="113" class="media-oembed-content" loading="eager" title="AutoDrive Challenge II Year 3 Highlight Video"></iframe> </div> </div> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 07 Aug 2024 17:42:55 +0000 Christopher.Sorensen 308926 at 91³Ô¹Ï researchers enhance object-tracking abilities of self-driving cars /news/u-t-researchers-enhance-object-tracking-abilities-self-driving-cars <span class="field field--name-title field--type-string field--label-hidden">91³Ô¹Ï researchers enhance object-tracking abilities of self-driving cars</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2024-05/PXL_20230608_181335793-crop.jpg?h=7575563c&amp;itok=mDJZAkzx 370w, /sites/default/files/styles/news_banner_740/public/2024-05/PXL_20230608_181335793-crop.jpg?h=7575563c&amp;itok=VS33Oojz 740w, /sites/default/files/styles/news_banner_1110/public/2024-05/PXL_20230608_181335793-crop.jpg?h=7575563c&amp;itok=lwAIt_Pp 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2024-05/PXL_20230608_181335793-crop.jpg?h=7575563c&amp;itok=mDJZAkzx" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>rahul.kalvapalle</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2024-05-29T10:59:42-04:00" title="Wednesday, May 29, 2024 - 10:59" class="datetime">Wed, 05/29/2024 - 10:59</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>Sandro Papais, a PhD student, is the co-author of a new paper that introduces a graph-based optimization method to improve object tracking for self-driving cars&nbsp;(photo courtesy of aUToronto)</em></p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/taxonomy/term/6738" hreflang="en">Safa Jinje</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/artificial-intelligence" hreflang="en">Artificial Intelligence</a></div> <div class="field__item"><a href="/news/tags/faculty-applied-science-engineering" hreflang="en">Faculty of Applied Science &amp;

For example, there is a human&nbsp;crossing the street at the intersection, or a cyclist changing lanes up ahead,†says&nbsp;<strong>Sandro Papais</strong>, a PhD student in UTIAS in the Faculty of Applied Science &amp; 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.â€&nbsp;</p> <p><a href="https://arxiv.org/pdf/2402.17892">In a new paper</a> presented at the 2024 International Conference on Robotics and Automation in Yokohama, Japan, Papais and co-authors <strong>Robert Ren</strong>, a third-year engineering science student, and Professor <strong>Steven Waslander</strong>, director of UTIAS’s <a href="https://www.trailab.utias.utoronto.ca/">Toronto Robotics and AI Laboratory</a>, introduce Sliding Window Tracker (SWTrack) – a graph-based optimization method that uses additional temporal information to prevent missed objects.</p> <p>The tool is designed to improve the performance of tracking methods, particularly when objects are occluded from the robot’s point of view.&nbsp;</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2024-05/Objects%20and%20Labels.jpg?itok=mTZFj1NL" width="750" height="426" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>A visualization of a nuScenes dataset used by the researchers.

The data includes human annotations that the team used to benchmark the performance of SWTrack.&nbsp;&nbsp;</p> <p>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.&nbsp;&nbsp;&nbsp;</p> <p>“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.&nbsp;</p> <p>Papais says he’s looking forward to building on the idea of improving robot memory and extending it to other areas of robotics infrastructure.&nbsp;“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.â€&nbsp;&nbsp;</p> <p>Another paper, <a href="https://arxiv.org/pdf/2402.12303">co-authored by master’s student <strong>Chang Won (John) Lee</strong> and Waslander</a>, introduces UncertaintyTrack, a collection of extensions for 2D tracking-by-detection methods that leverages probabilistic object detection.&nbsp;&nbsp;&nbsp;</p> <p>“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&nbsp;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.&nbsp;&nbsp;</p> <p>“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.â€â€¯&nbsp;&nbsp;</p> <p>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.&nbsp;&nbsp;“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.</p> <p>Waslander says the advancements outlined in the two papers build on work that his lab has been focusing on for a number of years.</p> <p>“[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.</p> <p>“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.â€&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 29 May 2024 14:59:42 +0000 rahul.kalvapalle 307958 at Three takeaways from Waabi CEO Raquel Urtasun’s entrepreneurial journey /news/three-takeaways-waabi-ceo-raquel-urtasun-s-entrepreneurial-journey <span class="field field--name-title field--type-string field--label-hidden">Three takeaways from Waabi CEO Raquel Urtasun’s entrepreneurial journey</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-03-09-True-Blue-Impact-Day_Polina-Teif-28-crop.jpg?h=afdc3185&amp;itok=5LPTXbW1 370w, /sites/default/files/styles/news_banner_740/public/2023-03-09-True-Blue-Impact-Day_Polina-Teif-28-crop.jpg?h=afdc3185&amp;itok=3nMWOmtL 740w, /sites/default/files/styles/news_banner_1110/public/2023-03-09-True-Blue-Impact-Day_Polina-Teif-28-crop.jpg?h=afdc3185&amp;itok=MgIFi7Bw 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-03-09-True-Blue-Impact-Day_Polina-Teif-28-crop.jpg?h=afdc3185&amp;itok=5LPTXbW1" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>mattimar</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-03-15T12:00:54-04:00" title="Wednesday, March 15, 2023 - 12:00" class="datetime">Wed, 03/15/2023 - 12:00</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Raquel Urtasun, a professor of computer science and founder and CEO of self-driving startup Waabi, delivers a talk during the Desjardins Speakers Series at 91³Ô¹Ï's Entrepreneurship Week (photo by Polina Teif)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/mariam-matti" hreflang="en">Mariam Matti</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/entrepreneurship-week" hreflang="en">Entrepreneurship Week</a></div> <div class="field__item"><a href="/news/tags/u-t-entrepreneurship" hreflang="en">91³Ô¹Ï Entrepreneurship</a></div> <div class="field__item"><a href="/news/tags/artificial-intelligence" hreflang="en">Artificial Intelligence</a></div> <div class="field__item"><a href="/news/tags/centre-engineering-innovation-entrepreneurship" hreflang="en">Centre for Engineering Innovation &amp; Entrepreneurship</a></div> <div class="field__item"><a href="/news/tags/computer-science" hreflang="en">Computer Science</a></div> <div class="field__item"><a href="/news/tags/faculty-arts-science" hreflang="en">Faculty of Arts &amp; Science</a></div> <div class="field__item"><a href="/news/tags/raquel-urtasun" hreflang="en">Raquel Urtasun</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/self-driving-cars" hreflang="en">Self-Driving Cars</a></div> <div class="field__item"><a href="/news/tags/startups" hreflang="en">Startups</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><b>Raquel Urtasun </b>may be a world-leading expert in machine learning and computer vision – but that doesn’t mean she likes to talk about her abilities.</p> <p>In fact, the CEO of self-driving vehicle company Waabi says she had to overcome her humble nature when trying to convince big-name investors<b> </b>she had the winning formula to transform the self-driving industry<b>.</b></p> <p>“You need to say [to venture capitalists] – why you, why this team and why this technology in a way that’s very convincing,†says Urtasun.</p> <p>The approach worked.

She adds that she knew from the beginning she wanted to work with investors from the technology and AI sector – including fellow 91³Ô¹Ï AI luminaries <b>Geoffrey Hinton</b> and <b>Sanja Fidler</b> – because they would better understand Waabi’s mission.</p> <p>“I think it’s important to have people you can rely on and that have each other’s back,†she says.</p> <p>The investments from Uber, Khosla Ventures, BDC Capital and others have allowed the company to develop Waabi World, an advanced simulator to test its autonomous vehicles, and Waabi Driver, its first generation of self-driving trucks.</p> <h4>Ignore the competition</h4> <p>“My philosophy is to write a strategy and focus on that,†Urtasun says, adding that it’s important to tune out naysayers.</p> <p>Case in point: When she first founded the company two years ago, she says she heard people say that she was getting into the self-driving sector “too late.â€</p> <p>“What I heard a lot was ‘everybody’s in this path, what are you doing?’ What I hear today is ‘how did you perfectly time this?’†she says. “And nothing changed, right?

It is a key component of the sensor suite – which also includes traditional radar and visual cameras similar to those found in smartphones – that enables a self-driving vehicle to build up a 3D representation of its surroundings.</p> <p><img alt src="/sites/default/files/aUTorontoinAnnArbor-crop.jpg" style="width: 750px; height: 500px;"></p> <p><em>Members of the aUToronto team with their winning perception cart at MCity in Ann Arbor, Mich&nbsp;(photo courtesy of&nbsp;aUToronto)</em></p> <p>In addition to being declared the overall winner, the 91³Ô¹Ï Engineering team received top marks in a wide range of categories, including the concept design event, the traffic light challenge and mobility innovation.</p> <p>One of the most dramatic parts of the competition was the dynamic object detection challenge, during which the cart had to detect and avoid a mannequin of a deer.</p> <p>“In the final testing session, the team realized their segmentation code was failing due to a change to the deer mannequin being used,†says Waslander.</p> <p>“Having planned for just such an event, they immediately switched to high gear. They took and labelled over 2,000 images of the new deer, then spent the whole night training and tweaking a brand-new detector. It worked brilliantly in competition the next day, securing first place.â€</p> <p>Qian says he is very proud of all that the team has accomplished.</p> <p>“This year with so many newer members, training became very important,†he says. “We also lost some precious development time due to challenges associated with COVID-19.

But, according to the 91³Ô¹Ï’s <b>Steven Waslander</b>, there’s one scenario that hasn’t yet received nearly as much attention as it deserves: winter.&nbsp;</p> <p>“Winter conditions aggravate the remaining challenges in autonomous driving,†says Waslander, an associate professor at the 91³Ô¹Ï Institute for Aerospace Studies in the Faculty of Applied Science &amp; Engineering.</p> <p>“Reduced visibility limits perception performance, and slippery road surfaces are a big challenge for vehicle control.â€</p> <p>To drive safely in all conditions, including winter, Waslander says autonomous vehicles need to fully observe their surroundings despite limits to their sensor range to get advanced warning of challenging situations and to react quickly to changing conditions.</p> <p>Along with fellow 91³Ô¹Ï Engineering researchers and members of the&nbsp;<a href="https://robotics.utoronto.ca/">91³Ô¹Ï Robotics Institute</a> – including&nbsp;<a href="https://news.engineering.utoronto.ca/tag/tim-barfoot/"><b><span style="text-decoration-line:none">Timothy Barfoot</span></b></a>,&nbsp;<a href="https://news.engineering.utoronto.ca/tag/jonathan-kelly/"><b><span style="text-decoration-line:none">Jonathan Kelly</span></b></a>&nbsp;and&nbsp;<a href="https://news.engineering.utoronto.ca/tag/angela-schoellig/"><b><span style="text-decoration-line:none">Angela Schoellig</span></b></a>&nbsp;– Waslander is leading a new partnership that will address these challenges by bringing together the best minds from academia and industry. The project, called WinTOR: Autonomous Driving in Adverse Conditions, is a new collaboration that aims to transform Toronto into a global hub for research and development related to autonomous driving in winter. Corporate partners include leading companies in the autonomous vehicles sector such as General Motors Canada, LG Electronics, Applanix and Algolux.</p> <p>It's one of six projects from 91³Ô¹Ï to receive <a href="https://news.ontario.ca/en/release/1000443/ontario-invests-in-research-and-innovation">support from the Ontario Research Fund</a>.

We’re committed to developing these initiatives to a scale that can attract support from government, philanthropic or industry sources – and WinTOR is a terrific example.â€</p> <p>&nbsp;</p> <div class="media_embed" height="422px" width="750px"><iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen frameborder="0" height="422px" src="https://www.youtube.com/embed/HXOPBwKZFaQ" title="YouTube video player" width="750px"></iframe></div> <p>&nbsp;</p> <p>The WinTOR team already has a track record of success. Last year, Waslander and his collaborators published the&nbsp;<a href="https://news.engineering.utoronto.ca/can-self-driving-cars-handle-a-canadian-winter-were-about-to-find-out/">Canadian Adverse Driving Conditions (CADC)</a>&nbsp;dataset. Created using the&nbsp;<a href="https://uwaterloo.ca/centre-automotive-research/watcar-autonomoose/about-autonomoose">Autonomoose</a>,&nbsp;a self-driving vehicle designed by Waslander and his team, the open-source data record real winter driving conditions on roads in southwestern Ontario.</p> <p>The valuable dataset is already being used by researchers from around the world to train new AI software. It joins a long list of research accomplishments from the project’s research team, whose combined expertise covers the full extent of autonomous driving perception and planning domains, including object detection and tracking, robust state estimation and calibration, localization and mapping, prediction and planning and safety-critical learning control.</p> <p><a href="https://news.engineering.utoronto.ca/tag/autonomous-vehicles/"><i>Read more about autonomous vehicle research at 91³Ô¹Ï Engineering</i></a></p> <p>All four professors are advisers to the&nbsp;<a href="https://www.autodrive.utoronto.ca/">aUToronto</a>&nbsp;team, a group of undergraduate and graduate students who have designed and built a self-driving electric vehicle called Zeus. The 91³Ô¹Ï Engineering team has&nbsp;<a href="https://news.engineering.utoronto.ca/autodrive-challenge-u-of-t-engineering-places-first-for-the-fourth-straight-year/">placed first in the international AutoDrive Challenge</a>&nbsp;in each of the four annual competitions to date.</p> <p>The new partnership is supported by more than $12 million in funding from a variety of sources. In addition to the Ontario Research Fund, that includes funding from the Natural Sciences and Engineering Research Council of Canada, as well as direct and in-kind donations from the project partners. More than 20 individuals will work as part of the team, including graduate and undergraduate students, professors and engineers.</p> <p>“We are excited to understand how we can apply the collaborative research under this program to real-world scenarios,†says Louis Nastro, director, land and autonomous vehicle strategy at Applanix. “It gives us an opportunity to attract highly talented individuals with the experience needed to join our team, and helps Canada establish itself as a leading provider of advancement in autonomy.â€</p> <p>“Algolux’s mission is to solve the issue of computer vision robustness in harsh driving conditions, a fundamental problem not effectively addressed by current approaches,†says Felix Heide,&nbsp;co-founder and chief technology officer of Algolux. “As a Canadian company, we are thrilled to bring our expertise to this project and continue to advance the state-of-the-art in perception technologies.â€</p> <p>“We are excited and proud to be a partner of this initiative,†says <b>Kevin Ferreira</b>, director of the LG Electronics Toronto AI Lab. “It is challenging to drive social impact with game changing technology in a fast-moving industry such as autonomous driving.</p> <p>Partnerships and collaborations, such as this initiative, are an effective strategy to make contributions to the research community, and to deliver impactful applications that improve safety while driving.â€</p> <p>The WinTOR project is divided into three broad themes:</p> <ul type="disc"> <li>Sensor filtering for object detection<b>:&nbsp;</b>New ways of analyzing the data from sensors such as visual cameras, radar and lidar will help to separate the signals that represent real objects from the noise caused by falling or blowing snow. Strategies will include both pre-processing techniques and improved artificial intelligence algorithms trained to be aware of the limits of their own performance.</li> <li>Sensor fusion, localization and tracking: While today’s self-driving cars can reliably determine where they are in relation to their surroundings, the techniques they use begin to break down under adverse driving conditions. The team will leverage new algorithmic strategies in vision and lidar registration, as well as new sensing options, such as ground-penetrating and automotive radar, to make localization algorithms more resilient in adverse conditions.</li> <li>Prediction, planning and control: self-driving cars of the future will need to change the way they drive in response to winter hazards. For example, they might take a slightly different path to avoid a snowdrift or slow down when driving over a section of road that their sensors have perceived as particularly slippery. They will learn the implications of adverse weather on the vehicles around them and be able to assess the increased uncertainty of outcomes, enabling them to plan actions that can be executed reliably in winter conditions.</li> </ul> <p>As ambitious as the current plan is, the team is just getting started. They are leveraging their network – including the 91³Ô¹Ï&nbsp;<a href="https://robotics.utoronto.ca/">Robotics Institute</a>, one of more than a dozen&nbsp;<a href="https://isi.utoronto.ca/initiatives/initiatives/">institutional strategic initiatives</a>&nbsp;at the university – to grow their team.</p> <p>“We continue to seek additional faculty, partners and funding to grow the effort,†says Waslander. “We have many more ideas to work on, from multi-hypothesis prediction and interaction planning to attentive perception and explainable, efficient AI for autonomous driving.â€&nbsp;<a id="list" name="list"></a></p> <hr> <p><b>Here is the full list of 91³Ô¹Ï researchers who are leading projects that received Ontario Research Fund support:</b></p> <ul> <li><b>Konstantinos N.
