X-Pack has a machine learning module, which is for learning from patterns within data. Machine learning is a vast field that includes supervised learning, unsupervised learning, reinforcement learning, and other specialized areas such as deep learning. The machine learning module within X-Pack is limited to anomaly detection in time series data, which falls under the unsupervised learning branch of machine learning.

We will look at some X-Pack components in Chapter 8, Elastic X-Pack.
