DESCRIPTION:Prof. Christos Davatzikos\, University of Pennsylvania\, Phila
 delphia\, PA (USA)\nDISTINGUISHED LECTURE IN BIOLOGICAL ENGINEERING(sandwi
 ches served)Abstract:\nThis talk will review work at the Center for Biomed
 ical Image Computing and Analytics of UPenn on machine learning methods de
 veloped and applied to a number of neuroimaging problems. We review past w
 ork that focused on support vector machines to derive individualized diagn
 ostic and predictive indices\, and describe analytical approximation of st
 atistical significance maps that allow us to highlight which imaging featu
 res are important in a classification task. We will also describe a genera
 tive-discriminative formulation for extracting discriminative imaging feat
 ures via sparse non-negative matrix decompositions. We will then review cu
 rrent work on semi-supervised methods\, aiming to capture disease heteroge
 neity via probabilistic mapping of imaging data of normative populations t
 o populations with heterogeneous effects on these imaging features. Finall
 y\, we conclude with unsupervised methods aiming to summarize complex imag
 ing data by a small and interpretable features\, using resting state funct
 ional connectivity as an example. Applications to aging\, Alzheimer’s Di
 sease\, Schizophrenia and brain development are used to demonstrate potent
 ial clinical utility of these methods.Bio:Education:\nB.S. (Electrical Eng
