title: Machine learning Algorithms used by Elastic x-pack plugin
body: <p>Elastic X-pack plugin predicts the dynamic baseline for our data and according to that specifies the anomalies out of the box.</p>
  
  <p>All these stuff are getting done behind the scene. My question is this how xpack learns from previous data and dynamically change the baseline. Does that use a specific algorithm?</p>
  
  <p>Is there any document for this?</p>
