that involve more than two classes. Voting methods that consider preference among classes can therefore gain an advantage over methods that do not, such as plurality. 3.4 Noise matters The led datasets in Table 3, for example, shows great sensitivity of the voting methods to noise. The amount of noise in led datasets increases from 0% to 50%. One somewhat surprising outcome of the experiments,

when classifying test examples: classifying using the majority class (VFDTcMC) and classifying using naive Bayes (VFDTcNB) at leaves. The experimental work has been done using the Waveform and LED datasets These are well known artificial datasets. We have used the two versions of the Waveform dataset available at the UCI repository [1]. Both versions are problems with three classes. The first

S. Mathews Ave, Urbana, IL 61801 {,} Abstract This paper presents a theoretical model to predict the minimal achievable error, given a noise ratio #, in the LED data set problem. The motivation for developing this theoretical model is to understand and explain some of the results that different systems achieve when they solve the LED problem. Moreover, given a new

also experienced significant reduction with the error being halved (for DNA this represented an increase in accuracy from 67.9% to 86.8%!). The error reduction is least for the noisy KRK and LED data sets and for the presumably noisy medical diagnosis data sets. Eighty percent of the data sets which scored unimpressive error ratios (above 0.8) were noisy data sets. This finding is further explored

1. The relevant features are very sharply identified. Feature 1 gets maximum credit on account of being relevant for the most informative SVM, in this case decided purely by the input bias. LED Dataset This 10-class dataset, drawn from the UCI repository, consists of 200 training and 500 test examples of 24 binary-valued features each. The first 7 features are relevant, and correspond to LEDs on a

To study the performance we use a paired one-sided t-test on these runs, except for the LED dataset which was run using hold-out with a training set of 2000 instances and a test set of 4000 instances. 5.2 Experimental analysis of weighting methods Table 2 shows the experimental results for each

The LED dataset represents a faulty LED device where a certain button (a variable with eight values indicating which display to set on) should set a led device ON. Some of the devices react incorrectly to this
