timeeval-GutenTAG 1.4.2

A good Timeseries Anomaly Generator.

A good Timeseries Anomaly Generator.

GutenTAG is an extensible tool to generate time series datasets with and without anomalies. A GutenTAG time series consists of a single (univariate) or multiple (multivariate) channels containing a base oscillation with different anomalies at different positions and of different kinds.

tl;dr

1. Install GutenTAG from PyPI:

   pip install timeeval-gutenTAG
   

   GutenTAG supports Python 3.7, 3.8, 3.9, 3.10, and 3.11; all other requirements are installed with the pip-call above.

2. Create a generation configuration file example-config.yaml with the instructions to generate a single time series with two anomalies: A pattern anomaly in the middle and an amplitude anomaly at the end of the series. You can use the following content:

   timeseries:
   - name: demo
     length: 1000
     base-oscillations:
     - kind: sine
       frequency: 4.0
       amplitude: 1.0
       variance: 0.05
     anomalies:
     - position: middle
       length: 50
       kinds:
       - kind: pattern
         sinusoid_k: 10.0
     - position: end
       length: 10
       kinds:
       - kind: amplitude
         amplitude_factor: 1.5
   

3. Execute GutenTAG with a seed and let it plot the time series:

   gutenTAG --config-yaml example-config.yaml --seed 11 --no-save --plot
   

   You should see the following time series:
