MoBI Seminar: Individual Differences in Face Recognition Abilities
Mon, Feb 27, 2023 @ 11:00 AM - 12:00 PM

Speaker: Dr. Frédéric Gosselin, Full Professor, Département de Psychologie, Université de Montréal
Talk Title: Individual Differences in Face Recognition Abilities
Abstract: Abilities for face recognition vary greatly even among neurologically typical individuals. At one end of the spectrum, developmental prosopagnosics show great difficulty recognizing faces, despite not having sustained any brain injuries. At the other end of the spectrum, super-recognizers easily recognize faces they have not seen in years, even if these faces have physically changed in a substantial manner. Understanding how perceptual mechanisms are linked with individual abilities can offer important and straightforward insights for improving face processing in both individuals with poor face recognition abilities and people whose jobs require strong face processing ability. We recently characterised the brain computations of participants of various face recognition abilities using high-density electroencephalographic signals and a combination of behavioural tests, artificial neural network models, and machine learning analyses. We found that individual face recognition ability can be decoded from brain activity in an extended temporal interval for face and non-face objects. We show that both visual and semantic brain computations contribute to these individual differences.
Biography: Frédéric Gosselin is a Full Professor in the Département de psychologie at Université de Montréal, and, with Dr. Anne Gallagher, the co-founder and co-director of cerebrum. He is a world-leading expert in high-level vision. He is the co-inventor of the Bubbles technique. He has also developed the popular SHINE toolbox for controlling low-level image properties. In his research, he uses a combination of psychophysical, neuropsychological, brain imaging and computational methods. Recently, his work has focused on individual differences in face recognition abilities. Dr. Gosselin is the founder and CEO of Elephant Scientific Consulting Inc.. His company has been advising multinational corporations such as Unilever, Cirque du Soleil and Netflix for 20 years.

PHD Thesis Proposal (Meryem M'Hamdi)
Mon, Feb 27, 2023 @ 03:30 PM - 05:00 PM
Thomas Lord Department of Computer Science
University Calendar
Presentation Title: Towards More Human-Like Cross-lingual Transfer Learning
Abstract: Since their release, multilingual off-the-shelf representations such as M-BERT and other Transformer-based variants has gained tremendous popularity. Despite exhibiting surprisingly good zero-shot performance, they are often pre-trained and fine-tuned in a data-intensive manner and are less robust against data distribution shifts which is orthogonal to how humans learn. In this thesis proposal, we analyze and propose techniques to advance the capabilities of multilingual language models beyond this data-intensive identically distributed paradigm and more towards human-like cross-lingual transfer learning. We achieve that through human-inspired input requirements by adapting few-shot meta-learning approaches, human-inspired outcomes by understanding what it means to learn continually over a stream of languages, and cognitive human-learning strategies like spaced repetition to consolidate retention of knowledge learned across languages. We apply our techniques to information extraction, natural language understanding, question answering, and semantic search downstream tasks and analyze on typologically diverse benchmarks.

AME Seminar
Mon, Feb 27, 2023 @ 03:30 PM - 04:30 PM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Janet Ellzey, University of Texas at Austin
Talk Title: Humanitarian Engineering: Educating Bold, Responsible, and Innovative Leaders
Abstract: Humanitarian engineering, the application of engineering solutions to low-income or marginalized communities, is a growing field in the US and worldwide. Sometimes called development engineering, researchers and practitioners focus on culturally appropriate solutions for resource-constrained environments such as refugee camps or low-income communities. Engineering schools are increasingly recognizing the importance of training students in humanitarian engineering and are developing programs using different approaches, from student organizations to full degree programs. At the University of Texas at Austin, Dr. Janet Ellzey has built an academic certificate that provides students with several pathways to use their engineering skills to positively impact the world, including a design and build program in which student teams partner with local communities and an innovation program to develop new technologies for the International Federation of Red Cross and Red Crescent Societies. In this talk, Dr. Ellzey will discuss this exciting engineering field, describe the programs at UT-Austin with data on the diversity of students enrolled in the program, and present challenges and opportunities for universities wanting to enter this field.
Biography: Janet Ellzey is a professor of mechanical engineering and the Engineering Foundation Centennial Teaching Fellow in the Cockrell School of Engineering at the University of Texas at Austin. She received her BS and MS degrees in Mechanical Engineering from The University of Texas at Austin and her PhD from the University of California-Berkeley. After more than 30 years of conducting experimental and computational research in the field of combustion, she pivoted her career to focus on expanding unique educational opportunities for undergraduate students. Recognizing the enthusiasm that the current generation of students has for social justice, she launched a program in humanitarian engineering which she now directs. Through creative partnerships with local communities abroad as well as with major international organizations, she has developed a network to educate the next generation of leaders while positively impacting the world.
