The decision plane of support vector machine (SVM) is decided by a few support vectors (SVs) in the training set. If there exist overlapping regions among different classes, SVs mainly locate in the overlap regions. A number of approaches have been proposed to find the samples in overlapping regions to condense the training set. However, the performance of these approaches would degrade if there is...
Data pre-processing and cleansing play a vital role in data mining for ensuring good quality of data. Data cleansing tasks include imputation of missing values, and identification and correction of incorrect/noisy data. In this paper, we present a novel approach called Co-appearance based Analysis for Incorrect Records and Attribute-values Detection (CAIRAD). For a data set having incorrect/noisy...
