The
Thrill
of
Discovery:
Information
Visualization
for
High-Dimensional
Spaces
Abstract: Interactive
information
visualization
provide
researchers
with
remarkable
tools
for
discovery.
By
combining
powerful
data
mining
methods
with
user-controlled
interfaces,
users
are
beginning
to
benefit
from
these
potent
telescopes
for
high-dimensional
spaces.
They
can
begin
with
an
overview,
zoom
in
on
area
of
interest,
filter
out
unwanted
items,
and
the
click
for
details-on-demand.
With
careful
design
and
efficient
algorithms,
the
dynamic
queries
approach
to
data
exploration
can
provide
100 msec
updates
even
for
million-record
databases.
This talk will start by reviewing the growing commercial success stories such as www.spotfire.come, www.smartmoney.com/marketmap and www.hivegroup.com. Then it will cover recent research progress for visual exploration of large time series data applied to financial, eBay auction, and genomic data (www.cs.umd.edu/hcil/timesearch).
Our next step was to combine these key ideas to produce the Hierarchical Clustering Explorer 3.0 that now includes the rank-by-feature framework (www.cs.umd.edu/hcil/hce). By judiciously choosing from appropriate ranking criteria for low-dimensional axis-parallel projections, users can locate desired features of higher dimensional spaces. Demonstration will be shown.
