Distance based Outlier BasIs using Neighbors (DOBIN).

DOBIN is a pre-processing algorithm that constructs a set of basis
vectors tailored for outlier detection as described by _[1]. DOBIN
has a simple mathematical foundation and can be used as a dimension
reduction tool for outlier detection tasks.

Currently (only) implemented in R.

for outlier detection using DOBIN." Journal of Computational and Graphical
Statistics 30.1 (2021): 204-219.

[ENH] Dobin basis transformation (#3373)
c2ad310 
Implementation of Issue #3371

Distance based Outlier BasIs using Neighbors (DOBIN) is a new approach to select a set of basis vectors tailored for outlier detection. The transformation outputs are the new coordinate system (such that outliers are best retained in lower the dimensional feature space).
