Anomaly Detection. Time Series AR Training

This workflow trains an auto-regressive model to predict signal values. Only time series values from normal functioning conditions are used to train the model.

- Read 313 spectral amplitudes time series produced by the Pre-processing/Time Alignment & Visualization workflow - define training set with only normal data (till August 2007) - For each frequency bin, for each sensor, for each motor part: - train auto-regressive model on training set (Lag = 10) - write PMML model (313 models) Anomaly Detection: Time Series AR TrainingThis workflow trains an auto-regressive model to predict signal values. Only time series valuesfrom normal functioning conditions are used to train the model.
