Abstract:

The desire to understand the underlying geometry of multivariate
(multidimensional) problems has motivated several visualization methods to
augment our limited 3-Dimensional perception. After a short overview,
Parallel Coordinates are introduced and rigorously developed obtaining a
one-to-one mapping between subsets of N-space and subsets of 2-space. This
leads to constructions algorithms in N-space involving intersections,
proximity, interior point construction, "Line and Plane Topologies" useful
in approximations and Computer Vision, as well as Collision Avoidance
Algorithms for Air Traffic Control. It is a VISUAL Multidimensional
Coordinate system. Applications to Visual and Automatic Data Mining are
illustrated with real multivariate datasets (some with hundreds of
variables) together with a Decision Support system capable of doing
Feasibility, Trade-Off and Sensitivity Analyses in complex multivariate
processes.

Biography:

Alfred Inselberg received a Ph.D. in Applied Mathematics and Physics
(1965) from the University of Illinois (C-U campus) and was subsequently
employed at the IBM Scientific Centers and Research in the USA. Al also
held academic positions at the University of Illinois, UCLA, USC, Technion
and Ben-Gurion University in Israel. In 1996 he was elected Senior Fellow
at the San Diego Supercomputing Center. He invented and developed the
multidimensional visualization methodology known as "Parallel Coordinates"
authoring numerous technical papers; receiving several patents and awards.
As of 1995 he is a Professor at the School of Mathematical Sciences of Tel
Aviv University. His textbook on "Parallel Coordinates" is being released
by Springer in 2008.
