"Let Pictures Talk"
- Part 1: Interactive Visualization for Dynamic Modelling of Gene Expression Time Series
-
Modelling temporal relations from time-course gene expression data has
beenproven valuable in genomic disease diagnosis and genomic drug design.
Because suitable software packages are lacking, we developed VisGene, a
visual data mining system that facilitates the modelling of temporal
gene regulatory networks based on gene expression time series. VisGene
emphasises particularly the modelling of temporal relations. Since gene
expression data are essentially high-dimensional, short Multivariate
Time Series (MTS), the system reduces the dimensionality of the MTS before
constructing a gene regulatory network using Dynamic Bayesian Network
modelling methods. VisGene integrates the data mining algorithms in each
stage of data analysis with effective visualization techniques to allow
the investigation of the temporal relations between variables from
different perspectives.
- Part 2: Visualization with Euler Diagrams
- Euler diagrams provide attractive visualization of overlapping information, because they represent intersection and enclosure of sets in an easily understandable way. They can be used in a wide range of application areas, such as visualizing statistical data, ontologies and the results of database search queries. However, practical use of Euler diagrams has been held back by difficulties in generating diagrams automatically. Until recently algorithms could generate diagrams only for a limited subset of abstract descriptions. In our project we developed general algorithms that, given any abstract description, can generate usable Euler diagrams. We proposed a number of additional layout improvement techniques. Furthermore, we developed algorithms for drawing Euler diagrams that meet additional constraints: for example, all contours are drawn as circles, or an algorithm for adding new contours to an existing Euler diagram without changing the original layout.
