Clustering in Visual Exploration of Large Scale
Data
The goal of this research is the development of
novel and effective techniques for the
exploratory visualization of data of high
dimensionality and heterogeneous data types.
XmdvTool, a public-domain exploratory
visualization system, has been extended to
enable multiresolution processing of data sets
with nominal fields and hundreds of dimensions.
New representations of relationships between
dimensions facilitates this process.
The approach consists of developing techniques
and tools to effectively order, space, and
cluster dimensions and values within nominal
variables, to visualize the resulting information
in a multiresolution fashion, to interact with
the information spaces in an intuitive fashion,
and to access the data at a rate to support the
exploration process.
The research will enable analysts to study and
explore data sets of a much larger scale and
diversity than currently possible with existing
technology. A wide range of disciplines will be
affected, including the sciences, engineering,
and commerce.
