  1. HDDVis: An Interactive Tool for High DimensionalData Visualization by Mingyue Tan April 21st, 2004

  2. Domain & Task • To visualize High Dimensional LABELED Data • Labeled Data ? - a collection of elements that are drawn from disjointed clusters

  3. Challenges • Two demands - to convey the overall structure - to reflect the inter-cluster and intra-cluster relationships • Current implementations - no interaction - not very accessible

  4. Solution-infovis techniques • Dimensionality Reduction with linear transformations - selection & highlighting • Parallel Coordinates & scatter plots - brush & link • Query data values

  5. 64-dimensional Handwritten digits (0, 4, & 6) 1140 (=380 x3) samples

  6. 320- dimensional Handwritten digits 390 samples (39 for each digit)

  7. Strong Points multiple graphical representations many interactions extensibility Weakness Points in brush & link not shown in main window Interactively add & remove points - on graph - in value table Evaluation & Future Work
