Ensemble methods use large numbers of simpler AI units to solve complex problems. A common example is the random forest which combines the results of large numbers of decision trees, but other kinds of algorithms can be used for the simpler units. The combination method may be a simple vote, or may involve more complex weighting of the results of individual units.
