Theoretical, Computational and Experimental Regularity on Interdisciplinary, Large Data Sets

(CSE 598D, 2-5pm W, Leonhard 101, #schedule = 946924)

This is a course on computational methods for real world digital data, that is across scale, modality and application domains. We aim at automatic pattern discovery, comparison and learning. The content is based on a unique combination of group theory, statistical learning theory, and human/animal perception,  with an emphasis on discovering visually appealing patterns automatically and hands-on trainings on large data sets.

A related course taught last fall: COMPUTATIONAL REGULARITY

Course content will also be drawn from a successful US NSF and NSFC supported summer school on Vision, Learning and Pattern Recognition (VLPR 2012) with a theme of “Computer Vision in Biomedical Image Applications”

This course will not be offered again before 2015.
