Abstract: Interactive information visualization tools provide researchers
with remarkable capabilities to support discovery. By combining powerful data
mining methods with user-controlled interfaces, users are beginning to benefit
from these potent telescopes for high-dimensional data. 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 databases.
This talk will start by reviewing the growing commercial success stories such as www.spotfire.com, 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, medical, and genomic data (www.cs.umd.edu/hcil/timesearcher).
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. Finally, these strategies of unifying statistics with visualization are applied to network data and electronic health records (www.cs.umd.edu/hcil/lifelines2). Demonstrations will be shown.
