Outlier detection, also known as anomaly detection, has been a persistent and active research area for decades due to its wide range of applications in various fields. Many well-established methods have difficulty fitting the distribution of high-dimensional and complex data, making it difficult to detect outliers that have a low degree of deviation. To address this problem, we combine the distribution fitting capability of generative adversarial nets (GANs) with the specificity of the outlier detection problem and propose a GAN-based unsupervised outlier detection (GUOD) method. In a real dataset mixed with normal objects and outliers, the generator reconstruction error of the object is used as its own outlier factor. The top-n objects with the largest reconstruction errors are considered outliers. Extensive ex
