title: Random cut forest for detecting anomalies in periodic time series patterns
body: <p>I have time series data that measure volume of an activity by half an hour intervals.
  The activity has weekly periodic patterns e.g. at Monday morning the volume is highest, at weekends the volume is low, etc. 
  I couldn't understand whether RRCF detects periodic patterns and gives a different score to a volume ,that on Monday morning would be considered normal but on Thursday morning it would be abnormal.</p>
  
  <p>Of course any suggestion on any algorithm would be appreciated.</p>
