1. A computer implemented method for detecting cyber physical system behavior, 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 data from a plurality of sensors associated with the system; constructing a metrization of the data utilizing a data structuring; determining at least one ensemble and at least one summary variable from the metrized data; applying a thermodynamic formalism to the at least one summary variable to classify a plurality of system behaviors; identifying the system behaviors based at least in part on the classified behaviors; obtaining a baseline of the system associated with the classified behaviors; detecting an anomalous condition based on a deviation of the system behaviors from the baseline; and providing an output indicating the identified system behaviors or the anomalous condition.
