UMD Machine Learning Experts Present Multiple Papers and Workshops at ICML 2022

University of Maryland researchers focused on machine learning are well represented this week at the 39th International Conference on Machine Learning (ICML 2022) being held from July 17–23 in Baltimore.

The UMD researchers—a mix of faculty, postdocs and students—are presenting 18 papers and are featured in 18 workshops. Their research covers a wide range of topics such as measuring the robustness of neural networks, improving the accuracy of classifying images in uncommon settings, and leveraging human assistance to help AI agents cope with unfamiliar situations.

Many of the participating UMD faculty—Tom Goldstein, Aravind Srinivasan, Furong Huang, John Dickerson, Soheil Feizi, Pratap Tokekar and Dinesh Manocha—are part of the University of Maryland Center for Machine Learning.

These same faculty—as well as Hal Daumé III and Rama Chellappa—all have appointments in the University of Maryland Institute for Advanced Computer Studies (UMIACS), which provides substantial administrative and technical support for the machine learning center.

“We’re proud to see our machine learning experts, particularly our talented graduate students, represented so well at a major conference,” says Mihai Pop, professor of computer science and the director of UMIACS. “The work they are doing is important—impacting transportation, the financial sector, privacy and security, and much more—and will continue to evolve rapidly as new technologies and new scientific knowledge come into play.”
