MAD-GAN: Multivariate Anomaly Detection for Time Series Data with Generative Adversarial Networks
TL;DR: In this article, an unsupervised multivariate anomaly detection method based on Generative Adversarial Networks (GANs), using the Long Short-Term-Memory Recurrent Neural Networks (LSTM-RNN) as the base models (namely, the generator and discriminator) in the GAN framework, was proposed.

On the Surprising Behavior of Distance Metrics in High Dimensional Spaces
TL;DR: This paper examines the behavior of the commonly used L k norm and shows that the problem of meaningfulness in high dimensionality is sensitive to the value of k, which means that the Manhattan distance metric is consistently more preferable than the Euclidean distance metric for high dimensional data mining applications.
