Research on Classification Method of High-Dimensional Class-Imbalanced Data Sets Based on SVM

2017

In recent years, the problem of classification for high dimensional and class-imbalanced data is found in many fields like bioinformatics and so on. High dimensional problem result in bad classification results because of some combinations …

VCOS: A Novel Synergistic Oversampling Algorithm in Binary Imbalance Classification

2019 · IEEE Access

Learning from class-imbalanced data is a challenging problem as standard classification algorithms are designed to handle balanced class distributions. Scholars solve this problem by modifying classifiers or and generating artificial data by oversampling. The former …
