Classification: CPC F  G | IPC F  G

Claim 13:
14. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform operations comprising:
collecting data from sensors associated with cabin air compressors;
preprocessing the data by separating the data into time slots and applying a fast Fourier transform to the data within each of the time slots to generate training spectrograms;
designing a machine learning model;
training the machine learning model using the training spectrograms;
evaluating the machine learning model;
converting the machine learning model to a reduced machine learning model; and
deploying the reduced machine learning model to a microcontroller associated with a cabin air compressor; and
controlling the cabin air compressor by changing operation of one of: a variable diffuser, an anti-surge valve, an air cycle machine bypass valve (ABV) based on the reduced machine learning model.
