Abstract
Systems and methods are disclosed herein for detecting an anomaly in a discrete signal, where a long-term trend of the discrete signal is identified. Samples in the signal correspond to a number of data packets arriving at a location in a network within a time interval. The long-term trend is subtracted from the discrete signal to obtain a detrended signal. A cyclic pattern is identified in the detrended signal and is subtracted from the detrended signal to obtain a residual signal. Anomaly detection is performed on the residual signal.
