Most techniques for attribute selection in decision trees are biased towards attributes with many values, and several ad hoc solutions to this problem have appeared in the machine learning literature. Statistical tests for the existence of an association with a prespecified significance level provide a wellfounded basis for addressing the problem. However, many statistical tests are computed fr...

While methods for comparing two learning algorithms on a single data set have been scrutinized for quite some time already, the issue of statistical tests for comparisons of more algorithms on multiple data sets, which is even more essential to typical machine learning studies, has been all but ignored. This article reviews the current practice and then theoretically and empirically examines se...

This article teaches the multivariate analysis of variance (MANOVA) method for repeated measures analysis to researchers who are already familiar with regular analysis of variance (ANOVA) methods. Repeated measures designs are traditionally analyzed with mixed-model ANOVAS. However, sphericity violations markedly affect the true Type I error rates and power for the mixed-model tests. However, t...

Work on comparing a set of linguistic test scores for MT output to a set of the same tests’ scores for naturally-occurring target language text (Jones and Rusk 2000) broke new ground in automating MT Evaluation. However, the tests used were selected on an ad hoc basis. In this paper, we report on work to extend our understanding, through refinement and validation, of suitable linguistic tests i...

Most techniques for attribute selection in decision trees are biased towards attributes with many values, and several ad hoc solutions to this problem have appeared in the machine learning literature. Statistical tests for the existence of an association with a prespeciied signiicance level provide a well-founded basis for addressing the problem. However, many statistical tests are computed fro...

the intelligent transportation system (its) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. this system consists of many fixed and mobile nodes (vehicles, trains, vessels, air planes), wireless and wired telecommunication technologies to exchange information between mobile nodes or betwee...
