Running experiments.py recreates the plots used in the final 8-page version of the paper. Further calls explained therein produce further illuminating plots, which did not make it into the final 8-page version of the paper. Some of these require data from Prof. Steve Hoi in ./OARIMA_code_data/ which are distributed by an independent, permissive license.

To reuse the algorithms introduce by ourselves, see onlinelds.py for an implementation.
