The Thrill of Discovery: Information Visualization for High-Dimensional Spaces


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 areas of interest, filter out
unwanted items, and then click for details-on-demand. With careful
design and efficient algorithms, the dynamic queries approach to data
exploration can provide 100msec updates even for million-record

This talk will start by reviewing the growing commercial success
stories such as, and Then it will cover recent research progress for
visual exploration of large time series data applied to financial,
Ebay auction, and genomic data ( ).

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 ( By judiciously
choosing from appropriate ranking criteria for low-dimensional
axis-parallel projections, users can locate desired features of higher
dimensional spaces. Demonstrations will be shown.
