TECHNIQUES FOR MODELING BEHAVIORS OF SYSTEMS VIA TRANSFORMATIONS OF AUTHORITATIVE MODELS
First Claim
1. A computer-implemented method for generating a model for a behavior of a system, the method comprising:
- generating a first sample data that includes a first authoritative value that is obtained from an authoritative model based on a first combination of system parameters and a first measured value that represents the behavior of the system at the first combination of system parameters;
training an untrained mapping model based on the first sample data to generate a partially trained mapping model;
training the partially trained mapping model based on at least one other sample data to generate a trained mapping model, wherein the trained mapping model maps values obtained from the authoritative model to values that represent the behavior of the system at different combinations of system parameters; and
generating the model for the behavior of the system based on the trained mapping model and the authoritative model, wherein the model estimates the behavior of the system for different combinations of system parameters.

Abstract
In one embodiment, a model generator generates a new model for a behavior of a system based on an existing, authoritative model. First, a mapping generator generates a mapping model that maps authoritative values obtained via the authoritative model to measured values that represent the behavior of the system. Subsequently, the model generator creates the new model based on the authoritative model and the mapping model. In this fashion, the mapping model indirectly transforms the authoritative model to the new model based on the measured values. Advantageously, the authoritative model enables the model generator to increase a rate of accuracy improvement experienced while developing the new model compared to a rate of accuracy improvement that would be experienced were the new model to be generated based on conventional modeling techniques. In particular, for a given sampling budget, the model generator improves the accuracy of the new model.
