Center node: "fixing bias in reconstruction based anomaly detection with lipschitz discriminators"
  Abstract: Anomaly detection is a problem of great interest in medicine, finance, and other fields where error and fraud need to be detected and corrected. Existing deep learning methods for anomaly detection almost universally rely on autoencoder reconstruction error. Here we show that this approach exhibits intrinsic biases, which can lead to undesirable results. We show that reconstruction-based methods are sensitive to outliers and are biased towards reconstructing any outliers in the training data, and outliers within the convex hull of the data. For these reasons, we introduce a new discriminator-based unsupervised Lipschitz anomaly discriminator (LAD), which does not suffer as much from these biases. We train a Wasserstein discriminator, similar to the ones used in GANs, to detect the difference between the training data and corruptions of the training data. We show that this procedure successfully detects unseen anomalies with guarantees on those that have a certain Wasserstein distance from the data or corrupted training set. These corrections allow us to surpass state of the art anomaly detection methods on MNIST and perform comparably on CIFAR10.
