The adult human brain parenchyma contains a relatively large population of progenitor cells that can generate oligodendrocytes. Defects in these adult oligodendrocyte progenitor cells (OPCs) or in(More)
Feature Extraction, also known as Multidimensional Scaling, is a basic primitive associated with indexing, clustering, nearest neighbor searching and visualization. We consider the problem of feature extraction when the data-points are complex and the distance evaluation function is very expensive to evaluate. Examples of expensive distance evaluations(More)
The availability of large and diverse datasets has lead to many exciting opportunities for the development of tools for knowledge discovery. Artificial Intelligence algorithms have a long history of being used to analyze large and complex datasets. Recent studies have suggested that the commonly used diagnostic measure, the Body Mass Index, may not be the(More)
