Intelligent Systems Lab

ISL research is focused on learning high quality models from data. A focus is building models that generalize to unseen sources. Deep learning with adaptations for smaller datasets, especially medical image sets, is explored. Unlabeled data is modeled with clustering algorithms. Mixtures of labeled an unlabeled data are addressed with semi-supervised learning approaches. Of particular interest is big data for which Deep Neural Networks are often useful. Ensembles of different (and the same) types of models are considered, imbalanced data is continually addressed. Imprecision in intelligent systems is also a research topic. Some recent work focuses on learning prognostic models from medical images and clinical data, learning models of activity in very large information networks and clustering data in a network environment. An overall goal is to be able to group large sets of unlabeled data in useful ways, uncovering small, but important groups where they exist. Another goal is to be able to make accurate predictions from potentially large (at least partially) labeled data sets.
