References for machine learning and RCF
To learn more about machine learning and this algorithm, we suggest the following resources:
- 
					The article Robust Random Cut Forest (RRCF): A No Math Explanation provides a lucid explanation without the mathematical equations. 
- 
					The book The Elements of Statistical Learning: Data Mining, Inference, and Prediction, Second Edition (Springer Series in Statistics) provides a thorough foundation on machine learning. 
- 
					Random Cut Forest Based Anomaly Detection On Streams , a scholarly paper that dives deep into the technicalities of both anomaly detection and forecasting, with examples. 
A different approach to RCF appears in other AWS services. If you want to explore how RCF is used in other services, see the following:
