In detail, pairwise two-tailed t-tests indicate that there are seven data sets (cleveland, diabetes, ionosphere, liver sonar, waveform21, and waveform40) where NeC4.5 with µ = 0% is significantly more accurate than C4.5, while there is no significant difference on the

In detail, it obtains the best performance on seven data sets, i.e. annealing, credit, liver pima, soybean, wine and zoo. RemoveOnly obtains the best performance on three data sets, i.e. glass, hayes-roth and wine. It is surprising that Depuration obtains

Additionally, a sixth dataset, the colon CAD dataset, relates to colorectal cancer diagnosis using virtual colonoscopy derived from computer tomographic images. We will refer to this dataset as the colon CAD dataset. The

experimental results confirm this hypothesis: in cases where the leave-one-out crossvalidated classification accuracy of the NB classifier is poor in the absolute sense (as with the Liver Disorders data set), or in the relative sense with respect to the default classification accuracy (as with the Postoperative Patient data set), the class labeled colored images are somewhat blurred.

PEBLS and HOODG algorithms are not able to handle unknown values: thus, they are only used in the four datasets without unknown values (diabetes, heart, liver and lymphography). For each database and algorithm, a classification model is induced using the specified training set: when run with fixed default

On the cleveland, liver iris and glass (except k = 1) datasets, the weights learned by the individual accuracies always performed significantly better than the others.

to examine the performance of boosting Cox's proportional hazards model, I turn to a clinical trial for testing the drug DPCA for the treatment of primary biliary cirrhosis of the liver (PBC). This dataset has been the subject of several modern data analyses (Fleming and Harrington 1991). I tested this method by comparing the out-of-sample predictive performance of the linear Cox model to the Cox

From the results presented in Table 3 we can conclude that appropriate values of c for the liver disorder data set are c 2 [0, 2]. Dierences in the number of clusters when c 2 [0, 2] arise because of small clusters which contain less than 5 % of all instances. Thus using results of numerical experiments on these
