Informatics Research Seminar: Reduction of Re-Admissions to Hospitals Based on Actionable Knowledge Discovery and Personalization

September 13, 2017 @ 4:00 pm - 5:00 pm UTC+0

Speaker: Zbigniew W. Ras, PhD, DSc
Presented from UNC-C

Broadcast Link: Seminar

The Informatics Research Seminar Series is sponsored by Duke University and a collaboration with UNC-Chapel Hill, NCCU, UNC-Charlotte, and ECU. This series explores key areas in Health Informatics and include research results, overview of programs of research, basic, applied, and evaluative projects, as well as research from varied epistemological stances.

The concept of procedure paths as a sequence of procedures that a given patient undertakes to reach a desired treatment will be introduced. By clustering patients into subgroups that exhibit similar properties, the predictability of their procedure paths is improved, which is evaluated by calculating the entropy to measure the level of predictability of following procedures. The clustering approach is used essentially as a way to personalize patients according to their properties. The results presented are based on Florida HCUP datasets.

Zbigniew Ras, PhD, DSc is a professor of computer science at the University of North Carolina, Charlotte. He holds a professorship position in the Institute of Computer Science at Warsaw University of Technology as well as at the Polish-Japanese Academy of Information Technology, both in Poland. His PhD degree is from University of Warsaw and his DSc Degree from the Polish Academy of Sciences. In 2012, he was awarded a National Professorship Title by the President of Poland. Dr. Ras’ areas of specialization includes Knowledge Discovery and Data Mining, Recommender Systems, Music Information Retrieval, Flexible Query Answering, and Health Informatics. He is Editor-in-Chief of the Journal of Intelligent Information Systems (Springer), Editor-in Chief of the International Journal of Social Network Mining (IJSNM), and he served as the Deputy Editor-in-Chief of Fundamenta Informaticae Journal (IOS Press), till 2010.
