Claim One:
1. A computer implemented method for anomaly detection, the method comprising: utilizing one or more processors and associated memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for: receiving operational and dynamics data from a plurality of sensors associated with a plurality of devices; filtering the data, wherein said filtering the data comprises data smoothing and eliminating outlying data, the data smoothing comprising: Fourier transforming the dynamics data; extracting an amplitude and frequency for a plurality of pressure oscillation spectral bins over a time period; and calculating a backward running average; establishing a set of baseline dynamics data including calculating a reference mean for each dynamic based on identifying historical data values a. relating to a sliding time window, or b. corresponding to a database query establishing reference data requirements and tolerances; identifying previous points in time that satisfy said data requirements and tolerances; and averaging the value of dynamics data related to said identified points in time; eliminating data dependencies; generating an expected level of data variation; identifying an anomaly based on a deviation of the device data from the baseline data normalized by the expected level of data variation; optionally correlating the anomaly with potential causes; and providing an output indicating the anomaly.
