○ 초록: Automated computer vision systems have been applied in many domains including security, law enforcement, and personal devices, but recent reports indicate that these systems may produce biased results, discriminating against people in certain demographic groups. Identification and diagnosis of such model bias, however, are challenging tasks because modern computer vision systems rely complex, black-box models whose behaviors are hard to decode. In this talk, I will first introduce our new dataset, FairFace, which can be used to measure the biases of computer vision models for face attribute classification. The dataset contains 108,501 images which are balanced race in contrast to existing public face image datasets, which are dominated by White faces. I will also discuss our new framework which allows us to measure counterfactual fairness in computer vision models. By using a generative model for face attribute manipulation, our method can synthesize new facial images varying in the dimensions of gender and race, while keeping other information intact. Such images can then be used to measure the sensitivity of a computer vision model to gender or race related cues. Using this new dataset and method, I will demonstrate the biases of several public datasets and commercial services commonly used by researchers. 
○ 연사 소개: Jungseock Joo is an assistant professor in Communication at University of California, Los Angeles and a visiting researcher in Amazon Alexa AI. His research primarily focuses understanding multimodal human communication with computer vision and machine learning. His research employs various types of large scale multimodal media data such as TV news orline social media and examines how multimodal cues in these domains relate to public opinions and real world events. He has received more than $2M in extramural funding from the National Science Foundation, Hellman Foundation, Samsung, and other awards. His research has appeared in prestigious venues in both computer science and social sciences including PNAS, CVPR, ICCV, ACMMM, APSR, JoP, IJoC, and many others. He received Ph.D. in Computer Science from UCLA, M.S. in Computer Science from Columbia University, and B.S.E. in Computer Science and Engineering from Seoul National University. He was a research scientist at Facebook Applied Machine Learning & AI Research prior to joining UCLA in 2016.
