WOOSTER, Ohio — Sofia Visa, associate professor of computer science at The College of Wooster, will present "Thinking Like a Computer Scientist: Fuzzy Logic, Image-Based Search, and Big Tomatoes" at the second Faculty at Large lecture of the spring semester on Tuesday, March 24. The lecture, which is free and open to the public, begins at 11 a.m. in Lean Lecture Room of Wishart Hall (303 E. University St.).

Visa will take a lighthearted but informative look at the use of computing in three problem areas. The first involves her research on fuzzy-based classifiers that perform well on imbalanced data sets. This has application in such areas as detection of rare diseases and fraudulent credit card transactions. The second area uses a clustering-based segmentation algorithm on images. This has application in content-based image retrieval from large data sets of images. The third area presents Visa's most recent research in bioinformatics – classification of tomato fruits into nine shape categories using contour morphometric points.

Visa was born in Romania and earned her B.S. degree in mathematics and computer science from L. Blaga University in Sibiu, Romania, and her M.S. and Ph.D. in computer science from the Electrical & Computer Engineering and Computer Science Department (ECECS) at the University of Cincinnati. Her research interests focus on machine learning, including issues related to data classification, learning from imbalanced data sets, applications of learning algorithms in real-world problems, and bioinformatics. She has published more than 40 papers, and is a reviewer for several journals and conferences.
