Description

Per chat with @jcsg, I briefly tried the `LocalOutlierFactor` model. Posting early, will spend some more time for a detailed analysis of both the model and the results.

Per https://stackoverflow.com/a/36869611/3453958

> The NearestNeighbors class is unsupervised and can not be used for classification but only for nearest neighbor searches.
