We consider the problem of anomaly sequence detection under the general setting of unknown anomaly and anomaly-free models.  In particular, the anomaly time series is a stationary random process with unknown underlying probablitiy model.  The anomaly-free time series is also stationary but epsilon-distance away from all anomaly processes.  We present an approach that ties some of the classical problems in statistics, signal processing, and modern machine learning: innovations sequence, uniformity test, and generative adversary networks (GAN).
