August 28, 2020

UNIVERSITY PARK, Pa. — The College of Information Sciences and Technology was well-represented at the 2020 ACM Knowledge Discovery in Databases (KDD) Conference, held virtually Aug. 23-27.

The conference accepted 11 papers including Penn State researchers, 10 of which involve experts from the College of IST.

“Mining information from big data using data mining and machine learning is revolutionizing technology and society,” said Prasenjit Mitra, associate dean for research at the College of Information Sciences and Technology. “The variety of applications that College of IST researchers address, ranging from homeless youth, social media applications such as Snapchat, electronic health records to computer security, shows that our work impacts all aspects of our lives involving technology and beyond.”

Mitra added, “In the last five years, only about 18% of the papers submitted to this competitive premiere data mining conference on average were accepted, and having 10 papers accepted from Penn State with nine of them from researchers in the College of IST demonstrates that the University and the college are among the premier research organizations in the world in this area.”
