- W3203504005 abstract "This paper presents an approach to further improve the data reduction abilities of the traditional C4.5 algorithm by integrating the information gain ratio and forward stepwise regression algorithms. Motivated by the fact that the traditional C4.5 algorithm utilizes a full set of antecedent attributes without taking into consideration irrelevant attributes which is a precursor to spurious predictive model estimates. This study aims to overcome this drawback by developing and evaluating the performance of an importance-based attribute selection algorithm called the C4.5-Forward Stepwise (C4.5-FS) for improving the data reduction abilities of the traditional C4.5 classifiers. Five datasets with dimensionality ranging from 6 to 10,000 attributes were employed to evaluate the model performance. The goodness of fit for the modified and traditional C4.5 classifier was done using k-fold cross-validation based on a confusion matrix. Experimental results revealed that the C4.5-FS algorithm trained on fewer antecedent attributes improved the data reduction capabilities of the traditional C4.5 algorithm trained on a full set of antecedent attributes by achieving higher accuracy." @default.
