Claim 12:
13. 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 norm vector by computing a Euclidean distance value from each row of the computed demixed training matrix;
sort the computed norm vector in order of increasing value;
compute a percentile value for each row of the sorted norm vector; and
select the predefined anomaly threshold value as the Euclidean distance value associated with a row of the sorted norm vector having a computed percentile value greater than or equal to a predefined percentile value.
