Attribute space extension for decision forests often contribute to improving the ensemble accuracy. In this paper we suggest the use of a recent method for attribute space extension where the newly generated attributes that have high classification capacity are chosen for extension. In literature, it is shown that the inclusion of these new attributes in the attribute space increases the prediction...
In this study we argue that the traditional approach of evaluating the information quality of an anonymized (or otherwise modified) dataset is questionable. We propose a novel and simple approach to evaluate the information quality of a modified dataset, and thereby the quality of techniques that modify data. We carry out experiments on eleven datasets and the empirical results strongly support our...
In this paper we present a novel technique called iDMI that imputes missing values of a data set by combining a decision tree algorithm (DT) and an expectation-maximization (EMI) algorithm. We first divide a data set into horizontal segments through applying a DT algorithm such as C4.5, and then apply an EMI algorithm on each segment in order to impute the missing values belong to the segment. If...
