Presentation Transcript

  1. Never forget your primary wealth, your and your family’s health, it will be your hope and your family’s hope for ever.

  2. Exploring High-D Spaces with Multiform Matrices and Small Multiples by Alan MacEachren etc. • Presenter: • Xu Liu • Ming Luo

  3. Outline • Contribution • Main ideas • Demos • Critiques

  4. Contribution • GeoVISTA development environment • A general framework, ready for combination of any information visualization forms • Dynamically visualize information with user interaction • Explore high dimension by univariate and bivariate relations between attributes • Find most significant relations between attributes

  5. Multiform Bivariate small Multiple

  6. Multiform Bivariate small Multiple O O O

  7. Multiform Bivariate Matrix

  8. Multiform Bivariate Small Multiple and Matrix • Multiple and matrix are designed as generic JavaBean components, providing a Java interface through which any bivariate representation form (instantiated as a JavaBean) can communicate. • Visualization is updated dynamically with the user’s interaction

  9. Find most significant relations between attributes • Maximum conditional entropy between each pair of attributes • Generate an ordering of attributes, which keeps a hierarchical clustering • Select subspace interactively or automatically

  10. Generate an ordering of attributes • A node is an attribute • An edge is the maximum conditional entropy between two attributes

  11. Generate an ordering of attributes • A node is an attribute • An edge is the maximum conditional entropy between two attributes

  12. Select subspace

  13. Critiques • Grid-based space-filling display • It can not show more information than a simple scatterplot (maybe worse) • Color legend needs training • Rare visualization tools for more than 2 variables

  14. Demo • Basic Usage • Conditioning • Bi-variable: you see it’s hard to select colors • PCP: a good alternation for multi variable scatter plot • Bad example: who can tell me what’s going on here?

  15. THANKS! • You may find the demo at • http://unc.dl.sourceforge.net/sourceforge/geovistastudio/studiodemo1.zip • Enjoy!
