Generative adversarial networks are a class of generative algorithms that
have been widely used to produce state-of-the-art samples. In this paper, we
investigate GAN to perform anomaly detection on time series dataset. In order
to achieve this goal, a bibliography is made focusing on theoretical properties
of GAN and GAN used for anomaly detection. A Wasserstein GAN has been chosen to
learn the representation of normal data distribution and a stacked encoder with
the generator performs the anomaly detection. W-GAN with encoder seems to
produce state of the art anomaly detection scores on MNIST dataset and we
investigate its usage on multi-variate time series.
