Operation method and operation device of failure detection and classification model

An operation device of a failure detection and classification (FDC) model, comprising:

• a data acquisition unit, configured to continuously obtain a plurality of raw traces;
• a management unit, configured to determine whether the raw traces have started to be changed from a first waveform to a second waveform and determine whether at least N pieces in the race traces have been changed to the second waveform;
• a window cutting unit, configured to automatically segment the raw traces which have been changed to the second waveform to obtain a plurality of windows, if at least N pieces in the raw traces have been changed to the second waveform, wherein the management unit further automatically sets an algorithm for each of the windows;
• an indicator calculation unit, configured to obtain an indicator of each of the windows through each of the algorithms;
• the FDC model;
• and
• a training unit, configured to retrain the FDC model based on the indicators.
