Claim One:
1. A computer implemented method for temporal ranking in invariant networks comprising the steps of: considering an invariant network and a set of broken invariants in the invariant network; assuming, for each time point inside a window W, that each metric with broken invariants is affected by a fault at that time point; computing an expected pattern for each invariant of a metric with assumed fault, said pattern indicative of time points at which an invariant will be broken given that its associated metric was affected by a fault at time t; comparing the expected pattern with the pattern observed over the time window W; and determining a temporal score based on a match from the prior comparing, said determining comprises, based on observations up to a current time T, selecting an interval of length w, [T−w, T], such that an anomaly at any tε[T−w, T] can cause a broken invariant at T and using an ARX model setting w=arg max(n, m+k).
