We consider a Markov decision process subject to model uncertainty in a Bayesian framework, where we assume that the state process is observed but its law is unknown to the observer. In addition, while the state process and the controls are observed at timet, the actual cost that may depend on the unknown parameter is not known at timet. The controller optimizes the total cost by using a family of special risk measures, called risk filters, that are appropriately defined to take into account the model uncertainty of the controlled system. These key features lead to non-standard and non-trivial risk-averse control problems, for which we derive the Bellman principle of optimality. We illustrate the general theory on two practical examples: clinical trials and optimal investment.
