De64257nition A Bayesian nonparametric model is a Bayesian model on an in64257nitedimensional parameter space The parameter space is typically chosen as the set of all possi ble solutions for a given learning problem For example in a regression prob edu Laurent Itti Departments of Neuroscience and Computer Science USC Los Angeles 90089 ittiuscedu Abstract Many realworld problems have complicated objective functions To optimize such functions humans utilize sophisticated sequential decisionmaking .
