RCC-Dual-GAN: An Efficient Approach for Outlier Detection with Few Identified Anomalies

no code implementations7 Mar 2020 Zhe Li, Chunhua Sun, Chunli Liu, Xiayu Chen, Meng Wang, Yezheng Liu

To address these issues, we focus on semi-supervised outlier detection with few identified anomalies, in the hope of using limited labels to achieve high detection accuracy.
