Claim 14:
15. The non-transitory computer-readable medium of claim 1, wherein before projecting the observation vector, the computer-readable instructions further cause the computing device to:
compute a demixed training matrix using Q=S′WT, where Q indicates the demixed training matrix, S′ indicates the projected plurality of training observation vectors, W indicates the defined demixing matrix, and T indicates a transpose;
compute a mean value of the demixed training matrix;
compute a standard deviation value of the demixed training matrix; and
compute the predefined anomaly threshold value using Tanomaly=μ+pσ, where Tanomaly indicates the predefined anomaly threshold value, μ indicates the computed mean value, p indicates a predefined number of standard deviations, and σ indicates the computed standard deviation value.
