1. A virtual sensor network system comprising:

  • a memory configured to;

    store a virtual sensor model, an output parameter value default rate of change, and an output parameter value threshold rate of change; and

    a processor configured to;

    receive, as input parameter values, physical parameter values of a machine measured from a physical sensor;

    generate output parameter values based on the input parameter values and the virtual sensor model;

    make a comparison between a rate of change of the output parameter values to the output parameter value threshold rate of change; and

    generate a default output parameter value based on the comparison.
