Abstract:
|
The relatively new field of OODA has made a lot of progress during the recent SAMSI program. A particularly challenging aspect of this viewpoint, is populations of tree-structured objects. Deep challenges arose, which involve a marriage of ideas from statistics, geometry, and numerical analysis, because the space of trees is strongly non-Euclidean in nature. These challenges, together with some approaches to addressing them, are illustrated using a real data example, where each data point is the tree of blood vessels in one person's brain.
