New project focuses on rare categories

Associate Professor Jingrui He has been awarded a three-year, $500,000 grant from the National Science Foundation (NSF) to develop explainable techniques to detect and track rare categories. For her project, "RareXplain: A Computational Framework for Explainable Rare Category Analysis," she will focus on real-world problems where underrepresented, rare (abnormal) examples play critical roles, such as defective silicon wafers resulting from a new semiconductor manufacturing process and rare but severe complications (e.g., kidney failure) among diabetes patients.

"This problem of explainable rare category analysis was motivated by my collaboration with IBM Research and Mayo Clinic Arizona," said He. "In both semiconductor manufacturing and healthcare, the targets of interest are rare but of great importance. Existing models in this area are mostly black box in nature, making them difficult to be comprehended by domain experts with limited knowledge in AI."

According to He, the new project will bridge the gap between the imminent need to analyze complex rare categories and the inability of state-of-the-art techniques to address this problem in an effective, efficient, and explainable way.

He's general research theme is to design, build, and test a suite of automated and semi-automated methods to explore, understand, characterize, and predict real-world data by means of statistical machine learning. She received her PhD in machine learning from Carnegie Mellon University.

iSchool students present their research at Urbana City Council meeting

At the Urbana City Council meeting on May 9, students in the Community Data (IS 594) course presented their research on how communities are reducing gun violence. According to their instructor Chamee Yang, postdoctoral research associate with the iSchool, Community Data Clinic, and Just Infrastructures Initiative, the new course was designed as an experiential learning opportunity with a community engagement component, where students could gain research experience with real-world implications. Throughout the Spring 2022 semester, students worked in groups to explore community-driven approaches to prevent gun violence.

2021 Downs Intellectual Freedom Awards given to #FReadom Fighters and ALA Office for Intellectual Freedom staff

For libraries and librarians, 2021 was an especially challenging year in terms of the increase in attempts at censorship. According to the American Library Association (ALA) Office for Intellectual Freedom, the number of challenges to library materials more than tripled from 2020 to 2021. In addition, current estimates show that 82 to 97 percent of challenges go unreported, suggesting that the total number of challenges are significantly greater.

New project to improve health of patients with kidney failure

There are approximately 600,000 individuals in the U.S. who are undergoing hemodialysis (HD) therapy for kidney failure. In hemodialysis, a machine filters wastes, salts, and fluid from the blood when an individual's kidneys are no longer healthy enough to do this work adequately. While lifestyle changes such as getting more exercise and making better nutritional choices would benefit HD patients, they are not popular with patients—leading to poor health outcomes. A new project, led by Assistant Professor Jessie Chin, aims to boost HD patients' commitment to exercise through a long-term motivational interviewing conversational agent (LotMintBot).
