The majority of the data is real-world from a variety of sources such as AWS It is comprised of both real-worldĪnd artifical timeseries data containing labeled anomalous periods of
The NAB corpus of 58 timeseries data files is designed to provide data for Please see the wiki section on contributingįor discussion on posting algorithms to the scoreboard. † Algorithm was an entry to the 2016 NAB Competition.

**** We have included the results for RCF using an AWS proprietary implementation even though the algorithm code is not open source, the algorithm description is public and the code we used to run NAB on RCF is open source. The spread of scores for each profile are 7.95 to 16.83 for Standard, -1.56 to 2.14 for Reward Low FP, and 11.34 to 23.68 for Reward Low FN. *** Scores reflect the mean across a range of random seeds. Implementation details are in the detector's code. ** The original algorithm was modified for anomaly detection. * From NuPIC version 1.0 ( available on PyPI) the range in scores represents runs using different random seeds. the perfect detector), and a baseline of 0.0 is determined by the "null" detector (which makes no detections). The NAB scores are normalized such that the maximum possible is 100.0 (i.e. Unsupervised real-timeĪnomaly detection for streaming data. We encourage you to publish your results on running NAB, and share them withĪhmad, S., Lavin, A., Purdy, S., & Agha, Z.
