An NSET method and apparatus for modeling and monitoring the status of a system is disclosed. The NSET employs a nonlinear similarity operator in place of linear matrix multiplication, to estimate a set of sensor data based on learned reference data, responsive to receiving a set of actual sensor data. Regularization is used in the generation of the estimate. The estimated data values and the actual sensor data are differenced to produce residuals, which are statistically tested with a SPRT to detect anomalies. Cluster centers may be used to represent learned reference data. The detection of anomalies can be used advantageously for sensor calibration verification.
