Algorithm to detect data novelties

All Answers (3 Answers In All)

By Govind Answered 6 years ago

Am not sure about z score but you can use isolation forest algorithm to detect novelties.
 

By Joshna Answered 6 years ago

You can use isolation forest to detect outliers. Isolation forest’s principle is that outliers are far from the rest of the observations. 
To build a tree, the algorithm picks a feature(randomly) from the feature space and random split value ranging between minimums and maximums.
