Claim 6:
7. The system of claim 1, wherein the fault detection system is further configured to:
(a) divide a current system matrix into a first new matrix and a second new matrix;
(b) train a first system matrix using the first new matrix;
(c) train a second system matrix using the second new matrix;
(d) determine a first estimated data set by applying the MSET using the first system matrix to a respective portion of the on-line data;
(e) determine whether abnormal operating conditions exist within the respective portion of the on-line data by comparing the first estimated data set to the respective portion of the on-line data;
(f) responsive to determining that abnormal operating conditions exist within the respective portion of the on-line data:
determine whether a size of the first system matrix satisfies a size threshold, and
responsive to determining that the size of the first system matrix does not satisfy the size threshold, designate the first system matrix as the current system matrix;

(g) responsive to determining that normal operating conditions exist within the respective portion of the on-line data:
determine whether a size of the second system matrix satisfies the size threshold, and
responsive to determining that the size of the second system matrix does not satisfy the size threshold, designate the second system matrix as the current system matrix; and

(h) iteratively perform steps (a)-(h) until the size of the first system matrix or the size of the second system matrix satisfies the size threshold.
