ldbod - Local Density-Based Outlier Detection
Flexible procedures to compute local density-based outlier
scores for ranking outliers. Both exact and approximate nearest
neighbor search can be implemented, while also accommodating
multiple neighborhood sizes and four different local
density-based methods. It allows for referencing a random
subsample of the input data or a user specified reference data
set to compute outlier scores against, so both unsupervised and
semi-supervised outlier detection can be implemented.
