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


Hddvis an interactive tool for high dimensional data visualization

64-dimensional Handwritten digits (0, 4, & 6)

1140 (=380 x3) samples


Hddvis an interactive tool for high dimensional data visualization

  • 320- dimensional Handwritten digits

    390 samples (39 for each digit)


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
