%description
Fast and multi-threaded implementation of isolation forest (Liu, Ting,
Zhou (2008) <doi:10.1109/ICDM.2008.17>), extended isolation forest
(Hariri, Kind, Brunner (2018) <arXiv:1811.02141>), SCiForest (Liu, Ting,
Zhou (2010) <doi:10.1007/978-3-642-15883-4_18>), fair-cut forest (Cortes
(2021) <arXiv:2110:13402>), robust random-cut forest (Guha, Mishra, Roy,
Schrijvers (2016) <http://proceedings.mlr.press/v48/guha16.html>), and
customizable variations of them, for isolation-based outlier detection,
clustered outlier detection, distance or similarity approximation (Cortes
(2019) <arXiv:1910.12362>), isolation kernel calculation (Ting, Zhu, Zhou
(2018) <doi:10.1145/3219819.3219990>), and imputation of missing values
(Cortes (2019) <arXiv:1911.06646>), based on random or guided decision
tree splitting, and providing different metrics for scoring anomalies
based on isolation depth or density (Cortes (2021) <arXiv:2111.11639>).
Provides simple heuristics for fitting the model to categorical columns
and handling missing data, and offers options for varying between random
and guided splits, and for using different splitting criteria.
