In this paper, we address the problem of computing interpretable solutions to reinforcement learning (RL) problems. To this end, we propose a search algorithm over a space of simple losed-form formulas that are used to rank actions. We formalize the search for a high-performance policy as a multi-armed bandit problem where each arm corresponds to a candidate policy canonically represented by its shortest formula-based representation. Experiments, conducted on standard benchmarks, show that this approach manages to determine both efficient and interpretable solutions. [less ▲]

This paper introduces a novel algorithm for approximate policy search in continuous-state, discrete-action Markov decision processes (MDPs). Previous policy search approaches have typically used ad-hoc parameterizations developed for specific MDPs. In contrast, the novel algorithm employs a flexible policy parameterization, suitable for solving general discrete-action MDPs. The algorithm looks for the best closed-loop policy that can be represented using a given number of basis functions, where a discrete action is assigned to each basis function. The locations and shapes of the basis functions are optimized, together with the action assignments. This allows a large class of policies to be represented. The optimization is carried out with the cross-entropy method and evaluates the policies by their empirical return from a representative set of initial states. We report simulation experiments in which the algorithm reliably obtains good policies with only a small number of basis functions, albeit at sizable computational costs. [less ▲]

What variables influence the electoral behaviour of citizens voting in home country elections from abroad? Despite the growing interest of migration scholars for the topic of external voting, this question remains largely unanswered. Basing ourselves on the existing political science literature on electoral behaviour and on the migration literature on immigrants’ participation in host country politics, we isolate different hypotheses that explain emigrants’ preferences in home country politics. We then build four models of voters based on these hypotheses: the social group voter, the ideological voter, the interest-driven voter, and the transnational voter. In the second part of the paper, we verify the validity of these models using the results of a survey carried out with Bolivian emigrants who took part in the 2009 Bolivian presidential election from abroad. Overall, this article identifies the drivers of immigrant transnational political participation and contributes to current debates on social remittances. [less ▲]

The school is an agent of socialisation in which coexists a plurality of collective memories. The curriculum ensures the transmission of official memory. However, alternative collective memories might also be discussed by students and teachers. This leads to a competition of memories. More specifically, this observation may be made regarding the transmission of the Holocaust in Belgium. This emotional historical fact, classically taught according to the official curriculum, is nevertheless sometimes questioned. This is for example the case for non-Belgian students, who consider other possible memories and want to discuss about these. In order to analyze this possible competition between collective memories, we explored the speeches of young from multiple national origins in relation to the topic of the Holocaust. Two focus groups, differing on the basis of the national origin of the participants, were conducted with young students aged form sixteen to eighteen. The discourse analysis aimed at showing (1) if there is a competition between different collective memories, and (2) to what extent political arguments are mobilized by the students. [less ▲]
