Tutorial Slides Freely Available: How to create meaningful and generalizable results


Slides from the GECCO’13 tutorial “How to create meaningful and generalizable results” are freely available on SPOTSeven’s publication page.

Computational Intelligence (CI) methods have gained importance in several real-world domains such as process optimization, system identification, data mining, or statistical quality control. Tools, which determine the applicability of CI methods in these application domains in an objective manner, are lacking. Statistics provide methods for comparing algorithms on certain data sets. In the past, several test suites were presented and considered as state-of-the-art. However, there are several drawbacks of these test suites, namely:

  • problem instances are somehow artificial and have no direct link to real-world settings;
  • since there is a fixed number of test instances, algorithms can be fitted or tuned to this specific and very limited set of test functions. As a consequence, studies (benchmarks) provide insight into how these algorithms perform on this specific set of test instances, but no insight is gained in how they perform in general;
  • statistical tools for comparing several algorithms on different test problem instances are relatively complex and results are not easy to analyze.

In this tutorial, a methodology to overcome these difficulties is presented. It is based on standard ideas from statistics: analysis of variance and its extension to mixed models, see, e.g. [Chia10a]. This tutorial combines essential ideas from two approaches: problem generation and statistical analysis of computer experiments. This framework extends ideas presented in [Bart11g].The generalization of results from multi-objective optimization problems will also be addressed.
