Mis-specified model supplementation

A system effective to generate output of a simulation model in a simulation system, the system comprising:

• a memory configured to store a simulation model, wherein the simulation model includes a simulation operator;
• a simulation module configured to be in communication with the memory, the simulation module is configured to:
• generate observed output data based on the simulation operator;
• store the observed output data in the memory;
• generate model output data based on a high-fidelity operator;
• store the model output data in the memory;
• a supplementation module configured to be in communication with the memory, the supplementation module is configured to:
• retrieve the observed output data from the memory;
• optimize a generalization error of a distance measure between the observed output data and model output data;
• and
• determine a correction operator based on the optimized generalization error of the distance measure;
• a processor configured to be in communication with the simulation module and the supplementation module, the processor is configured to append the correction operator to the simulation operator to produce a supplemented operator without modifying the simulation operator;
• and
• the simulation module is further configured to generate supplemented output data by application of the simulation model with the supplemented operator on a set of inputs.
