Research

Data mining from biomedical data is a general interest of Dr. Hall and his colleagues. Dr. Hall's work has included predicting the secondary structure of proteins, drug discovery, and designation of `'interesting'' areas in magnetic resonance images of the brain. He and his co-workers have participated in the Fourth and Fifth Community-wide Experiments on the Critical Assessment of Techniques for Protein Structure Prediction, known as CASP-4 and CASP-5. Dr. Hall's more specific research interests include intelligent symbolic systems (including development of an effective automated method to determine patient eligibility for clinical trials), machine learning, pattern recognition, and integration of artificial intelligence into medical image processing. He and his co-workers are working on a multiyear, multi-institution project to bring automatic segmentation of tissues in brain images into the clinic, with automatic tracking of brain tumors a specific goal. Exploitation of imprecision with the use of fuzzy logic in pattern recognition, artificial intelligence, and learning is a research theme. Parallel learning systems are another area of interest. Methods of scaling fuzzy clustering algorithms to large amounts of data for exploratory analysis and to facilitate distributed learning is an emphasis. Dr. Hall and his co-workers have developed distributed boosting methods and several distributed approaches to machine learning. They also have developed dynamic neural networks, modified approaches to building accurate decision trees, and placed a particular emphasis on developing effective methodswith ensembles of classifiers. An ensemble might include a support factor machine, a decision tree, a neural network, and a rule learner.
