Borderline-SMOTE: a new over-sampling method in imbalanced data sets learning
TL;DR: Two new minority over-sampling methods are presented, borderline- SMOTE1 and borderline-SMOTE2, in which only the minority examples near the borderline are over- Sampling, which achieve better TP rate and F-value than SMOTE and random over-Sampling methods.

Chong Wang,Wenyuan Wang +1 more
TL;DR: This paper explores the kernel-based similarity measure by using term clustering and an affinity matrix of terms is constructed via the co-occurrence of the terms in both unsupervised and supervised ways.
