critical to consider values for the strength parameter outside the originally specified range. Table 5.3 shows the classification error rates of two empirical tests, on the Wisconsin breast cancer dataset from the UCI repository (699 patterns), and the Heart disease dataset from Statlog (270 patterns). An ensemble consisting of two networks, each with five hidden nodes, was trained using NC. We use

attributes were binary coded in a 1-out-of-n fashion. Data points with missing attributes were removed. Each attribute was normalized to have zero mean and 1= p d standard deviation. The four data sets were the Wisconsin breast cancer (n = 683, d = 9), the ionosphere (n = 351, d = 34), the Japanese credit screening (n = 653, d = 42), and the tic-tac-toe endgame (n = 958, d = 27) database. 84

well, compared to the previous studies. In another study, Setiono  used his rule extraction from ANNs algorithm [28, 29] to extract useful rules that can predict breast cancer from the Wisconsin dataset. He needed first to train an ANN using BP and achieved an accuracy level on the test data of approximately 94%. After applying his rule extraction technique, the accuracy of the extracted rule set

chosen as the final solution. In some cases the training sets were reduced in size to makeoverfitting more likely (so that complexity regularization with DOOM could have an effect). In three of the datasets (Credit Application, Wisconsin Breast Cancer and Pima Indians Diabetes), AdaBoost gained no advantage from using more than a single classifier. In these datasets, the number of classifiers was
