An Investigation on Topic Maps Based Document Classification with Unbalance Classes

Abstract: Classification of imbalanced data has become a widespread problem due to the fact that the most real world datasets are imbalanced. In a classification task, one of the challenges is to learn the feature-space of classification under class-imbalance setting. The majority classes generally have good representation of features in the learned classification function and the minority classes lack this representation; subsequently, the classification for these classes failed more often. In this paper, authors inves… Show more

“…The methods of trying to solve this can be divided into two types. The data-based methods (Baloch and Rafi, 2015;Ofek et al, 2017) make use of over-and undersampling to reduce the imbalance. The algorithmbased methods (Zhou and Liu, 2005;Lin et al, 2017) give extra reward to different classes.…”
