Motivated by the interest in relational reinforcement learning, we introduce a novel representation formalism, called logical Markov decision programs (LOMDPs), that integrates Markov Decision Processes with Logic Programs. Using LOMDPs one can compactly and declaratively represent complex relational Markov decision processes. Within this framework we then develop a theory of reinforcement lear...

In their Unifying Theories of Programming, Hoare & He use the alphabetised relational calculus to give denotational semantics to a wide variety of constructs taken from different programming paradigms. We give a tutorial introduction to the semantics of CSP processes. We start with a summarised introduction of the alphabetised relational calculus and the theory of designs, which are preconditio...

Much of humankind's remarkable mental aptitude can be attributed to analogical ability – the ability to perceive and use relational similarity. In this chapter, we present an overview of analogy and describe its component processes, including structural alignment and inference projection, evaluation, schema abstraction and re-representation. We discuss how these component processes lead to lear...

To contribute to the growing literature on comparative urban research, this article speaks theoretical and methodological challenges that underlie recent calls for relational approaches city-making. The analysis we develop highlights multiscalar transformations of relations power across time space, which reconstitute life within changing historical conjunctures. offers a working vocabulary appr...

The practice of labeling seems to allow children to make difficult relational similarity matches. Two experiments explore the cognitive processes of comparison and replacement that have been implicated in the beneficial effects of linguistic labeling. Since linguistic labels may be implicated in a number of these processes, our experiments used traditional non-linguistic labels (post-its) to pr...
