1. A method for adapting an empirical model used in monitoring a system, comprising the steps of:

  • receiving actual values of monitored parameters characterizing the system;

    generating from the empirical model estimates of the parameter values in response to receiving actual values;

    calculating a global similarity score for a comparison of a set of estimated parameter values and a related set of actual parameter values; and

    adapting the empirical model to account for at least some received actual values based on the global similarity score.
