Methods and systems for predictive modeling using a committee of models
First Claim
1. A method for controlling a process using a committee of predictive models, the process having a plurality of control settings and at least one probe data representative of state of the process, said method comprising the steps of:
- providing probe data of the at least one probe within a prediction inputs space to each model in the model committee so that each model generates a respective output;
retrieving peers of the at least one probe, wherein the peers are within the prediction inputs space;
determining a local performance of each model by calculating outputs from each model for each peer;
aggregating the model outputs;
generating a predictive output based on said aggregating; and
transmitting the predictive output for viewing by an operator.

Abstract
Methods and systems for predictive modeling are described. In one embodiment, the method is a method for controlling a process using a committee of predictive models. The process has a plurality of control settings and at least one probe data representative of state of the process. The method includes the steps of providing probe data to each model in the model committee so that each model generates a respective output, aggregating the model outputs, and generating a predictive output based on the aggregating.
