 DEMORESIDUALS classification of motor condition using residuals and grnn

 - Load vibration (accelerometers) and current data from induction motor
 - Generate complex sequence from vibration data (orbit)
 - Generate complex sequence from current data (Park's vector)
 - Feature extraction using frequency band analysis at some frequencies
 - Train SOM model on normal conditions
 - Compute residuals of this model for all conditions
 - Train GRNN classifier using residuals as inputs and known class labels
 - Test GRNN classifier on test data (gradual variation of condition)
 - Evaluate the classifier (using ROC curve etc.)

 Note: 
    this demo requires the data file "dataicann.mat" not distributed with
    the toolbox. It should be available for download in the UnioviSOM 
    web page.
