Abstract

This paper discusses three methods to test the significance of classification efficiency (i.e. the fraction of correctly classified patterns of a test set), which can be applied to multiple class problems: the exact probability test, the Monte-Carlo test and the x2 test. First, a short theoretical description of the three methods is given. The methods have been applied to different classification problems. A comparison is made in terms of the following criteria: required assumptions, power and time behaviour. To conclude, the paper describes a set of criteria for the selection of the appropriate classification efficiency testing method.
