In safety-critical systems, certain safety constraints must be satisfied before an operation can be performed. Such constraints typically depend on the state of the system at the ...
Markov Decision Processes (MDP) have been widely used as a framework for planning under uncertainty. They allow to compute optimal sequences of actions in order to achieve a given...
Abstract. It is common to think of a "learner model" as a global description of a student's understanding of domain content. We propose a notion of learner model whe...
