A principled approach to interactive hierarchical non-linear visualization of high-dimensional data
Hierarchical visualization systems are desirable because a single twodimensional visualization plot may not be sufficient to capture all of the interesting aspects of complex high-dimensional data sets. We extend an existing ...
Using directional curvatures to visualize folding patterns of the GTM projection manifolds
In data visualization, characterizing local geometric properties of non-linear projection manifolds provides the user with valuable additional information that can influence further steps in the data analysis. We take ...
