Research Summary

Optimization theory is rich mathematically while being very effective computationally in solving problems from diverse fields. My recent work has emphasized mathematical programming approaches to machine learning and data mining. I have used such approaches for training neural networks, feature selection, parsimonious approximation, clustering and massive data discrimination via support vector machines. My mathematical programming interests include error bounds for linear, nonlinear programs and variational inequalities, ill-posed optimization problems, optimization problems with equilibrium constraints as well as parallel distributed optimization algorithms and smoothing techniques. Another important aspect of my research is the use of mathematical programming techniques in diagnosing breast cancer. This has resulted in an accurate computerized diagnostic system which is in current use at University of Wisconsin Hospital.
