Overview

This is part of Machine Learning-Driven Anomaly Detection

What you will learn

It can also be described as multi-variate time series data. This kind of data has temporal as well as spatial correlation between the different variables.  They are the most complex among the 4 categories of data. Most of the good solutions are based on deep learning.

We will review a  set of deep learning papers highlighting their salient points for anomaly detection solution. Most of the solution is based on a combination of a recurrent network (RNN) and an autoencoder network (AE). RNN handles temporal correlation and AE handles spatial correlation.
