Supermodeling:  Consensus by Synchronization of Alternative Models

Computational models of an ongoing objective process, as in weather
forecasting, must continually assimilate new observational data as they 
run.
Both ``truth" and ``model" are chaotic systems that thus synchronize 
through
a limited exchange of information in one direction - a phenomenon that can
be characterized as machine perception. A recent suggestion has been to
envision the fusion of different models analogously, as 3-way 
synchronization
of the different models with reality. This phenomenon may be useful for
improving climate projection by combining a few different models that 
differ
in regard to the magnitude of global warming and regional predictions.
Several machine learning approaches have been proposed to train the
connections linking corresponding variables in the different models.
Stochastic approaches can avoid non-global local optima, but it seems 
likely
that an intelligent "expert system" approach would improve the supermodel.
