Preliminary list of abstracts

Note: We are using the fantastic MathJax JavaScript library to typeset the mathematics on this web page. You can right-click on a formula to zoom in or to select the rendering engine you like (all under 'Settings'). Under Firefox the default renderer turns out to be MathML (which is quick), but you might prefer the HTML-CSS renderer for more faithful LaTeX rendering.

Some approaches to dimension reduction for optimization.
Keywords: POD; GTM; krig
Tue, 15:45--16:30
  • Keane, Andy J. (School of Engineering Sciences, University of Southampton, United Kingdom)

This talk illustrates how Proper Orthogonal Decomposition (POD), Generative Topographic mapping (GTM) and Krigging can be used during design optimization to reduce the dimensionality of the problem being tackled. Although these methods do not completely solve all issues in this area they are powerful tools for use alongside more traditional approaches such as screening and principal componnent analysis. Exmaples from airframe and aeroengine design are used to illustrated the proposed approaches.
