OBGAN: Minority oversampling near borderline with generative adversarial networks

作者:

Highlights:

• OBGAN: A novel minority oversampling method with GAN for class imbalance problems.

• OBGAN generates data from minority region, but near the borderline.

• A novel GAN architecture with two discriminators and a loss function is proposed.

• Experimental results showed the proposed OBGAN outperformed benchmark methods.

• Hyperparameters were analyzed to be not too sensitive to achieve good performances.
