  • Publication number: 20240086711
    Abstract: Systems and methods are provided for validating an autoencoder for a printing system. In one embodiment, a system stores values associated with individual features at a printing system and further stores times indicating when the values were determined at the printing system. The system also operates an autoencoder to perform time-compression upon the values and the times. Validating the autoencoder includes: determining predictive powers of the individual features prior to time-compression via partial F tests, determining predictive powers of the individual features after time-compression via partial F tests, and determining differences between the predictive powers of the individual features before time-compression and the predictive powers of the individual features after time-compression. Depending upon differences in the predictive powers, a report is generated indicating validity or invalidity of the autoencoder.
