Galichet, Nicolas. "Contributions to Multi-Armed Bandits : Risk-Awareness and Sub-Sampling for Linear Contextual Bandits." Thesis, Paris 11, 2015. http://www.theses.fr/2015PA112242/document.
Повний текст джерелаThis thesis focuses on sequential decision making in unknown environment, and more particularly on the Multi-Armed Bandit (MAB) setting, defined by Lai and Robbins in the 50s. During the last decade, many theoretical and algorithmic studies have been aimed at cthe exploration vs exploitation tradeoff at the core of MABs, where Exploitation is biased toward the best options visited so far while Exploration is biased toward options rarely visited, to enforce the discovery of the the true best choices. MAB applications range from medicine (the elicitation of the best prescriptions) to e-commerce (recommendations, advertisements) and optimal policies (e.g., in the energy domain). The contributions presented in this dissertation tackle the exploration vs exploitation dilemma under two angles. The first contribution is centered on risk avoidance. Exploration in unknown environments often has adverse effects: for instance exploratory trajectories of a robot can entail physical damages for the robot or its environment. We thus define the exploration vs exploitation vs safety (EES) tradeoff, and propose three new algorithms addressing the EES dilemma. Firstly and under strong assumptions, the MIN algorithm provides a robust behavior with guarantees of logarithmic regret, matching the state of the art with a high robustness w.r.t. hyper-parameter setting (as opposed to, e.g. UCB (Auer 2002)). Secondly, the MARAB algorithm aims at optimizing the cumulative 'Conditional Value at Risk' (CVar) rewards, originated from the economics domain, with excellent empirical performances compared to (Sani et al. 2012), though without any theoretical guarantees. Finally, the MARABOUT algorithm modifies the CVar estimation and yields both theoretical guarantees and a good empirical behavior. The second contribution concerns the contextual bandit setting, where additional informations are provided to support the decision making, such as the user details in the ontent recommendation domain, or the patient history in the medical domain. The study focuses on how to make a choice between two arms with different numbers of samples. Traditionally, a confidence region is derived for each arm based on the associated samples, and the 'Optimism in front of the unknown' principle implements the choice of the arm with maximal upper confidence bound. An alternative, pioneered by (Baransi et al. 2014), and called BESA, proceeds instead by subsampling without replacement the larger sample set. In this framework, we designed a contextual bandit algorithm based on sub-sampling without replacement, relaxing the (unrealistic) assumption that all arm reward distributions rely on the same parameter. The CL-BESA algorithm yields both theoretical guarantees of logarithmic regret and good empirical behavior

Повний текст джерелаCette thèse examine d’une part, l’impact des droits de propriété foncière sur la performance des petits producteurs agricoles et d’autre part, le rôle de l’aversion au risque dans la diversification des cultures au niveau des exploitations agricoles. Elle est subdivisée en quatre chapitres. Le premier chapitre fait la revue critique des méthodes et résultats des études empiriques qui analysent l’impact des droits de propriété foncière sur la performance des petits producteurs agricoles des pays en développement. Il montre que les résultats des études empiriques antérieures sont contrastés quant aux effets réels du droit de propriété. L’hétérogénéité des résultats est liée à la fois aux techniques d’évaluation utilisées et au contexte local de gestion du système foncier. Toutefois, les résultats convergent vers une endogénéité entre le droit de propriété et la performance des producteurs dans les contextes où la gestion coutumière du foncier est prédominante. Le deuxième chapitre analyse l’impact des droits de propriété foncière sur l’adoption des innovations agro-environnementales. Il utilise la méthode d’appariement par score de propension pour sélectionner les observations ayant les mêmes caractéristiques observables pour tenir compte du biais de sélection sur les variables observables. Il se base ensuite sur le modèle d’effet de traitement endogène multinomial développé par Deb et Trivedi (2006) pour tenir compte de l’endogénéité entre le droit de propriété et l’adoption d’innovation agro-environnementale. Le chapitre utilise des données détaillées au niveau des parcelles collectées au Bénin sur un échantillon de 2 800 petits producteurs et 4 233 parcelles. Il montre que les petits producteurs adoptent plus intensément les innovations agro-environnementales sur les parcelles dont ils sont propriétaires en comparaison aux parcelles prêtées, louées ou en métayage. Le troisième chapitre utilise le modèle de sélection de Greene (2010) pour les fonctions stochastiques de frontière appliquée à une fonction de distance en output et en combinaison avec la méthode d’appariement pour analyser l’impact de la sécurité foncière sur l’efficacité technique des petits producteurs agricoles. Il utilise également la méthode non paramétrique DEA (méthode d’enveloppement des données) pour analyser l’effet de la sécurité foncière sur la productivité agricole et décomposer cet effet en écart d’efficacité technique et en écart technologique entre les propriétaires terriens et les non-propriétaires. En se basant sur les données d’enquête au Bénin, il montre que les non-propriétaires ont en moyenne un niveau d’efficacité technique plus élevé et sont plus productifs que les propriétaires terriens. Par contre, les propriétaires affichent un net avantage technologique. Le quatrième chapitre porte sur l’effet de l’aversion au risque sur la diversification des cultures chez les petits producteurs agricoles au Burkina Faso. Une expérience terrain sous forme de loterie a été conduite pour mesurer l’aversion au risque des producteurs. Trois indices de diversité spatiale adaptés de la littérature en économie de l’environnement ont été utilisés pour mesurer la diversification des cultures au niveau des exploitations agricoles. Les résultats montrent que l’aversion au risque a un effet négatif et significatif sur la diversification des cultures. Les producteurs averses au risque se concentrent plus sur la production des cultures traditionnelles moins risquées et à faible valeur marchande.
This thesis examines the impact of land property rights on the performance of smallholder farmers and the role of risk aversion in crop diversification at the farm level. The dissertation is structured in four chapters. The first chapter provides a literature review of the methods and results of empirical studies that analyze the impact of land property rights on the performance of smallholder farmers in developing countries. It shows that the results of previous empirical studies are mixed about the real effects of property rights. The heterogeneity of the results is related both to the evaluation techniques used and to the local context of the tenure system’s management. However, the results converge towards an endogeneity between the property rights and the performance of smallholder farmers in contexts where customary land management is predominant. The second chapter analyzes the impact of land tenure differences on the adoption of agri-environmental innovations. It uses the propensity score matching method to select observations with the same observable characteristics to account for selection bias stemming from observed variables. In addition, possible self-selection arising from unobserved variables is addressed using a multinomial endogenous treatment effect model developed by Deb and Trivedi (2006). The chapter uses detailed cross-sectional plot-level dataset collected in Benin and covering a sample of 2,800 smallholder farmers and 4,233 plots. The results indicate that the intensity of the adoption of agri-environmental practices is consistently higher on owned plots than borrowed, rented or sharecropped plots. The third chapter uses the sample selection model introduced by Greene (2010) in stochastic frontier functions applied to a distance function in output and in combination with the matching method to analyze the impact of land security on technical efficiency of smallholder farmers in Benin. It also uses the non-parametric DEA (Data Envelopment Analysis) to analyze the effect of land tenure on agricultural productivity and to decompose this effect into a technical efficiency gap and technological differential between landowners and non-owners. The results show that non-owners are on average more productive than landowners because of their greater technical efficiency, while landowners have a technological advantage. The fourth chapter examines the effect of risk aversion on crop diversification among smallholder farmers in Burkina Faso. A field experiment in a form of lottery was conducted to measure producers' risk aversion. To measure crop diversification, we use three indices of spatial diversity in crop species adapted from the ecological economics literature. The results show that risk aversion has a negative and significant effect on crop diversification. Risk-averse producers focus more on the production of traditional, less risky and low market value crops.
