Description: "Mining multidimensional Data through Visualisation"


                        Abstract



The premise of using visualisation to mine multidimensional 
data is that the user can search for any features they deem 
interesting. 'Interesting' can change from domain to 
domain, user to user or time to time. Multidimensional data 
is hard to visualise because humans are not adept at 
working in more than three dimensions. In this talk I 
present a compositional approach to the problem. Data is 
decomposed into a set of simpler data modules, those 
modules are individually visualised and the visualisation 
modules are composed to form a larger, more complex 
visualisation instance. However, the composed visualisation 
is not always an accurate depiction of the original data 
(this will be discussed).

I'll show how visualisation can be used for data mining. 
Then I'll present the model and apply it to a visualisation 
tool I've developed which uses VE technology. Finally I'll 
talk about whether VEs help for such applications.

This talk is about my PhD thesis. I'll cover it's main 
points and show some examples. Your feedback is appreciated.
