MarginMatch: Improving Semi-Supervised Learning with Pseudo-Margins

Rezumat: „In this talk, I will present MarginMatch, a new SSL approach that combines consistency regularization and pseudo-labeling, and its main novelty arises from the use of unlabeled data training dynamics to measure pseudo-label data quality. Instead of using only the model’s confidence on an unlabeled example at an arbitrary iteration to decide if the example should be masked or not, MarginMatch also analyzes the behavior of the model on the pseudo-labeled examples as the training progresses, to ensure low quality predictions are masked out. MarginMatch brings substantial improvements on four vision benchmarks in low data regimes and on two large-scale datasets, emphasizing the importance of enforcing high-quality pseudo-labels.” 

Bio Speaker: Cornelia Caragea is a Professor of Computer Science and the Director of the Information Retrieval Research Laboratory at the University of Illinois Chicago (UIC). She received her Ph.D. in Computer Science from Iowa State University and her B.S. in Computer Science and Mathematics from the University of Bucharest. Her research interests are in natural language processing, artificial intelligence, deep learning, machine learning, and information retrieval. Caragea’s work has been recognized with several National Science Foundation (NSF) research awards, including the prestigious NSF CAREER award. She has published many research papers in top venues such as ACL, EMNLP, NAACL, ICML, AAAI, and IJCAI and was a program committee member for many such conferences. She reviewed for many journals including Nature, ACM TIST, JAIR, and TACL, served on many NSF review panels, and organized several workshops on scholarly big data. In 2020-21, she received the College of Engineering (COE) Research Award, which is awarded to faculty in the College of Engineering at UIC for excellent research contributions. Caragea was included on an Elsevier list of the top 2% of scientists in their fields for her single-year impact in 2020.
