Legrand, Juliette. "Simulation and assessment of multivariate extreme models for environmental data". Electronic Thesis or Diss., université Paris-Saclay, 2022. http://www.theses.fr/2022UPASJ015.
Texto completoAccurate estimation of the occurrence probabilities of extreme environmental events is a major issue for risk assessment. For example, in coastal engineering, the design of structures installed at or near the coasts must be such that they can withstand the most severe events they may encounter in their lifetime. This thesis focuses on the simulation of multivariate extremes, motivated by applications to significant wave height, and on the evaluation of models predicting the occurrences of extreme events.In the first part of the manuscript, we propose and study a stochastic simulator that, given offshore conditions, produces jointly offshore and coastal extreme significant wave heights (Hs). We rely on bivariate Peaks over Threshold and develop a non-parametric simulation scheme of bivariate generalised Pareto distributions. From such joint simulator, we derive a conditional simulation model. Both simulation algorithms are applied to numerical experiments and to extreme Hs near the French Brittanny coast. A further development is addressed regarding the marginal modelling of Hs. To take into account non-stationarities, we adapt the extended generalised Pareto model, letting the marginal parameters vary with the peak period and the peak direction.The second part of this thesis provides a more theoretical development. To evaluate different prediction models for extremes, we study the specific case of binary classifiers, which are the simplest type of forecasting and decision-making situation: an extreme event did or did not occur. Risk functions adapted to binary classifiers of extreme events are developed, answering our second question. Their properties are derived under the framework of multivariate regular variation and hidden regular variation, allowing to handle finer types of asymptotic independence. This framework is applied to extreme river discharges
Baudet, Cédric. "L'évaluation de l'efficacité des systèmes d’information : des situations normales aux situations extrêmes". Thesis, Lyon, 2019. http://www.theses.fr/2019LYSE3038.
Texto completoHow to evaluate the efficiency of an information system (IS)? The efficiency of an IS intended for a normal management situation must be assessed differently from an IS intended for an extreme situation. This is explained by the peripheral role of IS intended for normal situations and, conversely, by the "core" role of IS intended for extreme situations. Proposing this answer required a two-step process, which, in its entirety, underlines the concern of practitioners and researchers regarding the question of evaluating the efficiency of IS.As a first step, a literature review of the IS evaluation was conducted. An interpretative analysis as well as a bibliometric statistical analysis of the scientific literature and practitioners revealed the characteristics of the concept of IS evaluation. These characteristics were analyzed by thematic coding. The result is, on the one hand, to highlight the convergences and divergences between the points of view of researchers and practitioners on the notion of evaluation in IS; on the other hand, to propose maturity levels for evaluating the efficiency of an IS.In a second step, cases of e-government IS were studied. It is through a Design Science (DSR) approach that an artifact was designed and evaluated that operationalizes DeLone and McLean's (1992, 2003, 2016) success model contextualized to Girin's (1990) management situations. This artifact makes it possible to 1) evaluate the efficiency of an e-government IS for either a normal management situation or an extreme situation; 2) measure the maturity of an organization's IS efficiency evaluation process. In addition to answering the research question posed in this thesis, this artifact made it possible to clarify the paradoxical role of IS intended for extreme management situations. In addition, it should reconcile practitioners and researchers on how to evaluate an IS
Hmad, Ouadie. "Evaluation et optimisation des performances de fonctions pour la surveillance de turboréacteurs". Thesis, Troyes, 2013. http://www.theses.fr/2013TROY0029.
Texto completoThis thesis deals with monitoring systems of turbojet engines. The development of such systems requires a performance evaluation and optimization phase prior to their introduction in operation. The work has been focused on this phase, and more specifically on the performance of the detection and the prognostic functions of two systems. Performances metrics related to each of these functions as well as their estimate have been defined. The monitored systems are, on the one hand, the start sequence for the detection function and on the other hand, the oil consumption for the prognostic function. The used data come from flights in operation without degradation, simulations of degradation were necessary for the performance assessment. Optimization of detection performance was obtained by tuning a threshold on the decision statistics taking into account the airlines requirements in terms of good detection rate and false alarm rate. Two approaches have been considered and their performances have been compared for their best configurations. Prognostic performances of over oil consumption, simulated using Gamma processes, have been assessed on the basis of the relevance of maintenance decision induced by the prognostic. This thesis has allowed quantifying and improving the performance of the two considered functions to meet the airlines requirements. Other possible improvements are proposed as prospects to conclude this thesis
Dang, Thanh Ha. "Mesures de discrimination et leurs applications en apprentissage inductif". Phd thesis, Université Pierre et Marie Curie - Paris VI, 2007. http://tel.archives-ouvertes.fr/tel-00184691.
Texto completoDe façon générale, un système construit par apprentissage inductif a pour but de discriminer les individus de différentes classes. Sa qualité dépend de la capacité de discrimination qu'il acquiert au cours de l'apprentissage au travers des données. En particulier, un algorithme de construction d'arbre de décision procède par évaluation successive de la capacité de discrimination des attributs pour construire l'arbre de décision.
Nos travaux concernent l'étude des mesures de discrimination tant classiques que floues, et leurs applications en apprentissage inductif.
D'une part, nous nous intéressons aux mesures de discrimination dans la construction des arbres de décision. Dans un premier temps, ces mesures font l'objet d'une étude selon une approche axiomatique. Nous développons un nouveau modèle pour caractériser les mesures de discriminations floues. Dans un deuxième temps, nous proposons d'utiliser ces mesures dans les différentes étapes de la construction des arbres de décision flous.
D'autre part, nous étudions l'utilisation de ces mesures de discrimination pour d'autres aspects de l'apprentissage. Nous examinons tout d'abord le problème de l'évaluation des classifieurs et proposons une méthode basée sur l'utilisation de la notion de capacité de discrimination. Enfin, nous considérons le problème du traitement des données manquantes et proposons une technique de substitution des valeurs manquantes, qui restitue la capacité de discrimination des attributs.
Ces travaux sont validés sur des données conventionnelles et appliqués à des données réelles dans le cadre de deux applications qui concernent la classification de courriers électroniques et la classification de traces d'interactions homme-machine.
