Domain task
Domain & Task

  • To visualize High Dimensional LABELED Data

  • Labeled Data ?

    - a collection of elements that are drawn from disjointed clusters


Challenges
Challenges

  • Two demands

    - to convey the overall structure

    - to reflect the inter-cluster and intra-cluster relationships

  • Current implementations

    - no interaction

    - not very accessible


Solution infovis techniques
Solution-infovis techniques

  • Dimensionality Reduction with linear transformations

    - selection & highlighting

  • Parallel Coordinates & scatter plots

    - brush & link

  • Query data values




Evaluation future work

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
